- Description: The callings songs of five species from three genera of South African pygmy bladder cicadas are analyzed. The call of each species has a distinct temporal pattern and frequency spectrum. The songs are of significantly lower frequency than would be predicted based on body mass or body length. Comparison of bladder cicada calls from Australia and South Africa show similar lower than predicted frequencies in species of independent evolutionary origin. The inflated abdomen found in these cicadas appears to be a convergent adaptation to permit more efficient song production at lower carrier frequencies that increase the distance the songs will travel.

- Description: publisher version , The polar regions are more critically affected by climate change than any other region on our planet.1,2 On the Antarctic continent and in its surrounding oceans, the effects of climate change are likely to be dramatic,3 and include largescale catastrophic ice melt, loss of habitat and biodiversity, and global sea level rise. The ‘Southern Ocean’ refers to the region where Atlantic, Indian and Pacific Ocean waters come together to encircle Antarctica. These waters connect the different ocean basins by linking the shallow and deep limbs of the global ocean current system (‘overturning circulation’) and play a critical role in storing and distributing heat and carbon dioxide (CO2 ). The Southern Ocean thus regulates not only the climate of the Antarctic, but of the entire earth system.1,4 By extension, the capacity of the global ocean to ameliorate earth’s changing climate is strongly controlled by the Southern Ocean. Marine phytoplankton (microscopic plants inhabiting the sunlit upper ocean) convert CO2 (an inorganic form of carbon) dissolved in surface waters into organic carbon through photosynthesis. This organic carbon fuels upper trophic levels such as fish, mammals and birds, and a portion sinks into the deep ocean where it remains stored for hundreds to thousands of years. This mechanism, which lowers the atmospheric concentration of CO2 , is termed the ‘biological pump’.5 The efficiency of the global ocean’s biological pump is currently limited by the Southern Ocean, where the macronutrients (nitrate and phosphate) required for photosynthesis are never fully consumed in surface waters. In theory, increased consumption of these nutrients could drive higher organic carbon removal to the deep ocean, enhancing the oceanic uptake of atmospheric CO2 . Indeed, more complete consumption of Southern Ocean nutrients is a leading hypothesis for the decrease in atmospheric CO2 that characterised the ice ages.6 Despite the global importance of the Southern Ocean, knowledge of the controls on and interactions among the physical, chemical and biological processes operating in Antarctic ecosystems is limited, largely because of a scarcity of in-situ observational data, compounded by the challenge of integrating siloed scientific fields. Given predictions that diverse aspects of Southern Ocean physics and carbon biogeochemistry are likely to change in the coming decades, a transdisciplinary approach to studying Antarctic systems is critical.

- Description: Over the years, human trafficking has become one of the fastest growing crimes in the world. According to a report of the United Nations Office on Drugs and Crime, Women and Children account for 75 percent of trafficked victims. Between 2007 and 2010, children accounted for 20 percent of the trafficked victims which is approximately 1343 children per year. Sadly, these statistics continue to rise annually. It is from this premise that no one can doubt the rationale behind the 2015 Immigration Regulations that affect children travelling in and out of South Africa. However, in terms of section 28 (2) of the Constitution of the Republic of South Africa, it is a prerequisite that in any matter affecting a child, the best interest of the child be of paramount importance. This mini dissertation seeks to establish whether these Immigration Regulations which initially came into effect in May 2014, are in the best interest of child travellers. This has been done by looking at the old system which regulated the movement of children; its loopholes and shortcomings, thereby establishing whether Regulation 6 (12) is a panacea or in fact the hallmark of a series of problems that have a detrimental effect on the well-being as well as the rights of the child. The research methodology is mainly based on a study of existing literature. This largely includes internet sources, national legislation, regional and international instruments as well as case law. The South African Immigration Act 2002 is the primary reference with regards to regulatory information. However, lessons are drawn from legislation from other jurisdictions, notably Zimbabwean Immigration laws as well as those of Namibia. This is because South Africa shares a border with Zimbabwe and it also has a historical connection with Namibia and has good relations with both States. The mini dissertation analyses the impact of the 2015 Immigration Regulations not only on children but on other sectors as well. Lastly, the latter makes recommendations on how to improve these Regulations without affecting the best interest of child travellers.

- Description: The intention of this treatise is to reflect on the concept, as well as on the theory, of conflict resolution and to investigate whether the mechanisms of true conflict resolution are afforded within the structures and instruments provided for by the South African Labour Relations Act (66 of 1995). The Act aims to give effect to one of its primary purpose of advancing labour peace by attempting to promote the effective resolution of labour disputes through a very sophisticated system of dispute resolution. What is of great significance is that The Commission for Conciliation, Mediation and Arbitration (CCMA) has been experiencing an increasingly high rate of disputes referred to it since its inception in 1996. In my review I established that the dispute resolution system is a construction of rules and statutes which concentrates on rights, rather than on conflict management. However, rights only imperfectly reflect basic human needs, which continue to dominate human behaviour mechanisms that indeed facilitate processes and guidelines of resolving labour disputes, but fail to acknowledge and make provision for the resolution of a latent or manifest conflict. The instruments afforded by the Labour Relations Act (66 of 1995) fail to explore and entertain the needs most relevant and significant to the perception of social conflicts such as security, identity, personal development and recognition as suggested by conflict theorists and scholars. It also fails to acknowledge that parties to a dispute undergo psychological changes that could flow over to community changes and group dynamics as the parties become polarised and become more contentious as the conflict escalates. My review gave more substance to my original assumption that the current South African labour dispute resolution system does not harmonize itself with its own objective of promoting true labour peace.

- Description: publisher version , South Africa celebrated 20 years of democracy in 2014. In 1994, life satisfaction among all South Africans peaked following the first open non-racial elections. Since that time, only some 45–55 % of the total population, on average, state that they are satisfied. Drawing on Alex Michalos’ classic Multiple Discrepancy Theory (MDT), this chapter explores the needs, expectations, aspirations and perceptions of progress among black South Africans, who were promised a better life under democracy by the new government they voted for in 1994. Findings suggest that expectations raised by the new government in the early years of democracy, coupled with a strong sense of entitlement to state services and welfare in later years, are among the strongest drivers of life satisfaction 20 years into democracy. South Africa’s democracy project is still a work in progress and black South Africans continue to hope for a better life in the future.

- Description: Although much research has been conducted on sustainable tourism and the education thereof internationally, a limited number of studies have focussed on education of sustainable tourism in South African secondary schools. A literature overview identified various approaches to the education of sustainability on the international front. Despite South Africa’s reliance on the tourism industry, the concept of sustainability has received little focus in classrooms where this pertinent issue should be receiving attention in order to ensure that future sustainability is ensured in the South African tourism industry. From the literature overview it was possible to identify topics pertaining to sustainability in the Tourism Curriculum and Assessment Policy Statement implemented in the Further Education and Training Phase (FET) in South African secondary schools. These assisted in the development of the research tool for this study. The New Ecological Paradigm (NEP), an instrument used to establish the level of environmental concerns of groups of people, also provided guidance in the development of the research tool. The primary objective of this study is to investigate the perceptions of Tourism educators in secondary schools towards sustainability. A framework to investigate this was developed and three hypotheses formulated. To give effect to this, an empirical investigation was conducted. Tourism educators who were successful in their application to mark 2014 National Senior Certificate Tourism examinations were included in the sample of this study. The result of the descriptive statistics performed on the data showed that the level of education of the respondents was the main contributing demographic that impacted on their perceptions of sustainable tourism. It is, however, of concern to note that a very low percentage of the respondents (6.2%) have received formal training in Tourism. This situation should be cause for concern for Tourism education in the Eastern Cape. Two of the three hypotheses were accepted. The researcher believes that specialised subject relevant training is required to empower educators to teach sustainable tourism in the South African secondary school classrooms in order to ensure future sustainability in the tourism industry of South Africa.

- Description: Being a part of various contemporary South African societies, we often find ourselves having to negotiate multiple dimensions of ourselves in our everyday lives amongst other culturally diverse people. These complex networks of identity, which define who we are, extend beyond the insular self into our daily interactions with others. This active methodology of existence requires social individuals to be able to embody a constant mobile identity, which when employed is not guaranteed to be socially successful. How then, do we cope with potential social failure and reflect on ourselves or our communal identities? For the submission of my Masters of Fine Art, I present the interactive exhibition, Space Station: a mini-golf art experience and the accompanying thesis,Space Station: Negotiating Identities in the Contemporary Performance Artscape. The exhibition manifests as a nine hole miniature golf course temporarily installed along a distance of unused train track in Grahamstown. The audience members’ or “players’” experiences of the exhibition draw attention to the subtle performances of everyday life as well as the ways in which identity is re-constructed through transitory mapped networking practices.The thesis interacts with the performed artwork, as not only a supporting text, but is activated, ‘performing’ in collaboration with the artwork’s temporary lived and present experiential journey. The thesis creates three fictional metaphoric characters: the pilgrim, the everyday migrant and the astral-bodied tourist who all negotiate contemporary urban space in order to explore ways in which mobile identity is socially practiced, developed and maintained.I argue that the Space Station audience member blurs between these characters, in the processes of ‘performing’ the game, by becoming the ‘player’. The research works alongside contemporary social environments to guide the audience and reader through positive self and socially reflective experiential processes to inspire rethinking around the interaction of habitual daily living.

- Description: Expansion of woody vegetation results in the transformation of a grass-dominated ecosystem to a tree-dominated ecosystem causing land degradation in most semi-arid areas. The imbalance in the natural ecosystem between herbaceous plants and woody vegetation poses a threat to the natural environment. Such changes alter the flow, availability and quality of nutrient resources in the biogeochemical cycle. Most of the dominating woody plants are often unpalatable to domestic livestock. Therefore, the objective is to assess the spatial extent of woody vegetation over time. Knowledge of the spatial and temporal characteristics of woody vegetation dynamics will enable the development of management plans. These characteristics can be derived using remote sensing techniques which have become efficient in such studies. This study aimed to characterize woody vegetation dynamics along the route between Alice and King Williams’s town in Eastern Cape Province South Africa using Landsat data. This aim was achieved by focussing on three specific objectives. The first objective was to compare the performance of multispectral data and Normalized Difference Vegetation Index (NDVI) data of Landsat imagery in mapping woody vegetation cover. The second objective was to investigate the effect of the spatial resolution of remotely-sensed data on discrimination of woody vegetation from other land cover types. The third objective characterised woody vegetation dynamics between 1986 and 2013/2014 using the results from the first objective. The study used Landsat imagery acquired in November or February of 1986, 1994/1995, 2002/2003 and 2013/2014. Due to lack of data which covered the study area two separate dates (November and February) where used for the study resulting in naming the study area western and eastern parts. Unsupervised classification was performed on the multispectral, NDVI and pan-sharpened images to generate four generic land cover classes, namely water, bare land, grassland and woodland. Accuracy assessments of the classified images was done using error matrix. The results showed that the classification based on NDVI images yielded a better overall accuracy than the classification based on multispectral images for the western (83 percent and 75 percent, respectively) and eastern (82 percent and 76 percent, respectively) parts of the study area. Similarly, pan-sharpening resulted in better overall classification accuracy than multispectral, but comparable to the classification of the NDVI images for both the western (82 percent) and eastern (83 percent) parts of the study area. Remote sensing is an effective tool in assessing changes in the physical environment. Landsat imagery is suitable in assessing land cover dynamics given the long-term and free availability of the image. In addition, the large spatial coverage it provides, enables Landsat data to be used on studies that have wide spatial coverage. Classification for the purpose of time-series analysis was then performed on the NDVI images of each date (1986, 1994/1995, 2002/2003 and 2013/2014). Both woody vegetation and grassland experienced changes from 1986 to 2013/2014 with grassland occupying (75 percent) compared to woodland (17 percent) in 1986. In the year 2013/14 grassland occupied 32 percent and woodland occupied 51 percent of the study area. The increase in woody vegetation in the study area can be attributed to livestock rearing and migration of people from the rural to urban areas post-Apartheid. The study output will aid in the development of a database on land cover distribution of the area between King William’s town and Alice town, providing useful information to decision-making and further studies on woody vegetation.

- Description: An in-depth study of the electronic structure of a 1,4-diazabicyclo[2.2.2]octane (DABCO) induced molecular self-assembled xanthene-bridged and amide-bonded porphyrin dimer is reported. Density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations are used to identify trends in the optical spectroscopic properties. B3LYP geometry optimization predicts the formation of an almost perfectly eclipsed structure with respect to the two porphyrin rings with the analogous pyrrole nitrogens separated by 7.7–8.1 Å. The observed distinctive derivative-shaped band morphology of the pseudo-Faraday-A11 terms in the MCD spectra has been used to identify the main electronic Q and B-bands and to validate the TD-DFT calculations. The absence of a discernible splitting of the redox steps or a quenching of the fluorescence demonstrates that there is no significant exciton coupling between the two porphyrin rings.

- Description: The structure of the spermatozoon and spermatodesm of the spittlebug Locris transversa (Thunberg 1822) was investigated by light and transmission electron microscopy. Males produced only one size class of sperm, which was 93–106 μm long. During spermatogenesis groups of spermatozoa are arranged around, and attached by their acrosomes to, a small central extracellular matrix to form a ball-shaped spermatodesm. Spermatodesmata were found in the testis, vas deferens and seminal vesicle of males and spermatheca of females. The sperm are filiform, each consisting of a ~15-μm-long head containing an anteriorly positioned conical ~2-μm-long acrosome and ~13-μm-long nucleus, and a midpiece and tail with a 9+9+2 axoneme. The acrosome, which has two posterior extensions that lie along one side of the anterior region of the nucleus, contains longitudinally orientated microfilaments. The nucleus has two unequal anterior extensions, whereas posteriorly it is flattened laterally to accommodate a putative centriolar adjunct and anterior ends of the two mitochondrial derivatives. The basal body lies posterior to the nucleus. The mitochondrial derivatives are elongated and extend for almost the entire length of the tail. The tail has glycogen within its centre, and towards its terminal end large deposits of glycogen surround the mitochondrial derivatives and axoneme. Compared to other members of the Cicadomorpha, the spermatozoa and spermatodesms of cercopids so far studied have some structural features in common with cicadellids and others in common with cicadas; therefore, if sperm features are to be useful in phylogenetic studies of cicadomorphs, attention must be given to examining key taxa to establish which character states are plesiomorphic or apomorphic.

- Description: Since its inception, consumption behaviour theory has developed to account for the important social aspects that underpin or at least to some extent explain consumer behaviour. Empirical studies on consumption behaviour of cultural activities, entertainment and sport have used Bourdieu’s (1984) omnivore/univore theory to investigate consumption of leisure activities. The aim of this study is to investigate whether South African cricket spectators are sporting omnivores or univores. The study was conducted among cricket spectators in the Eastern Cape at four limited overs cricket matches in the 2012/2013 cricket season. The results indicate that consumption behaviour of sport predominantly differs on the grounds of education and race. This suggests that there are aspects of social connotations underpinning sports consumption behaviour within South Africa.

- Description: The concept of city branding has sprung to prominence in recent years. This can be attributed to globalisation and the ease of access to all corners of the globe with the improvements in technology and modes of transport. This increased competition for resources, skills, talent and revenue has made cities not only compete with other cities in close proximity to one another, but also with cities across the world. The answer to this conundrum was found to be a comprehensive marketing strategy composed of clever and catchy slogans, beautiful logos, media campaigns and public relations drives. This process only led to the loss of large amounts of money since the benefits were not longstanding and the results were not tangible as these avenues only benefitted the home country’s tourism industry. A long term solution for cities was needed to build a favourable image. Corporations were used as models to build a brand since manufacturers of similar products are in constant competition to gain market share and revenues from their competitors. The similarities between corporations and cities are undeniable and efforts were made to incorporate successful branding strategies from corporations into city branding efforts. Cities and corporations must be effective in developing and incorporating social, economic and political aspects of their culture into a successful city brand image. The major difference between cities and corporations stems from the fact that it takes considerably longer to leverage a comprehensive brand of a city, when compared to the brand of a product since their lifespans are completely different. In the past, city brands were based on historical significance. Today, city brands are exclusively influenced by the events it hosts. The hosting of events has been seen as a guaranteed way for a city to improve its brand image. On the contrary, the hosting of events has been found to either improve a city brand or tarnish it. Sports events have been deemed as the best way to improve a city brand because sports appeal to a wide audience and are relatively inexpensive to host in comparison to the benefit and improvements they bring. This treatise investigates the approach and various types of sports events which must be included for the successful branding of Nelson Mandela Bay as part of a destination marketing strategy. The suggestions from this study were formulated upon scrutiny of the available literature and case studies on various branding efforts undertaken by cities around the world to establish and improve their brand image. A survey was conducted amongst the residents of Nelson Mandela Bay using a questionnaire. A total of 952 responses were received. The questionnaire measured the respondents’ attitude to what types of sports events they will support, their feelings on the standard of facilities and quality of events in Nelson Mandela Bay. This treatise served to identify which sports events should be used in any branding effort undertaken by Nelson Mandela Bay. Literature and case studies served as the foundation for this study. The survey insights and expectations enabled a plan to be developed that will be unique for Nelson Mandela Bay based on its location, characteristics, tastes and preferences of its residents. This plan would serve to benefit the residents of Nelson Mandela Bay, the city itself and encourage additional investment from external sources. The results of this study indicate that the residents of Nelson Mandela Bay advocate the use of sports events as the main driver in branding the city. Furthermore, the residents have made it clear that cricket, rugby and Iron Man-type of events are favoured and more likely to be supported than any other type of sports event in Nelson Mandela Bay.

- Description: Sustainability reporting is becoming increasingly important, and governments and stock exchanges of many countries require or strongly encourage businesses to provide some level of sustainability reporting. South Africa is one of few emerging market economies and the only country in Africa which show substantial sustainability reporting activities. In South Africa, sustainable development has been recognised at a constitutional and legislative level. Companies listed on the Johannesburg Stock Exchange (JSE) must integrate sustainability reporting with financial reporting, or explain why they are not complying. Establishing a suitable sustainability reporting framework should therefore be part of the strategic integration of sustainability with other aspects of organisational planning and decision-making. This study suggests such a framework of standards and indicators for sustainability reporting in South African businesses, and evaluates it in South African listed companies. Mixed methods research was used in two phases. In phase 1, a critical analysis of the literature produced a framework of standards and indicators to be used as a measure to evaluate sustainability reporting in South Africa. In phase 2, first hand, original data was collected by performing a quantitative content analysis of sustainability reports of 84 companies listed on the Johannesburg stock exchange with the aim to identify standards and indicators that are applied in the content of sustainability reports in South Africa. Quantitative content analysis involves analysing material and then classifying it into various coding units or themes found in the material - it is a systematic way of converting text to numerical variables for quantitative data analysis.

- Description: The issues about child protection have become a global concern. With the increase in cases of child abuse, neglect and mal-treatment, this study sought to address such issues in the South African context. The government through the Department of Social Development introduced various statutory requirements to ensure the protection of vulnerable children in South Africa. Through the use of a qualitative approach, this study investigated the duties of social workers working within statutory interventions to ensure the safety of abused and neglected children in two distinct areas in Amathole District, Eastern Cape. Semi-structured interviews from the study indicated that, social workers play major roles to ensure that vulnerable children are catered for. Their duties which are guided by law have seen so many abused children being removed from their place of abuse to better places of safety. However, despite the vigorous work done by social workers, statutory interventions still faces many challenges which make them ineffective.

- Description: People who are voluntarily childless, or ‘‘childfree,’’ face considerable stigma. Researchers have begun to explore how these individuals respond to stigma, usually focusing on interpersonal stigma management strategies. We explored participants’ responses to stigma in a way that is cognisant of broader social norms and gender power relations. Using a feminist discursive psychology framework, we analysed women’s and men’s computer-assisted communication about their childfree status. Our analysis draws attention to ‘‘identity work’’ in the context of stigma. We show how the strategic use of ‘‘choice’’ rhetoric allowed participants to avoid stigmatised identities and was used in two contradictory ways. On the one hand, participants drew on a ‘‘childfree-by-choice script,’’ which enabled them to hold a positive identity of themselves as autonomous, rational, and responsible decision makers. On the other hand, they mobilised a ‘‘disavowal of choice script’’ that allowed a person who is unable to choose childlessness (for various reasons) to hold a blameless identity regarding deviation from the norm of parenthood. We demonstrate how choice rhetoric allowed participants to resist stigma and challenge pronatalism to some extent; we discuss the political potential of these scripts for reproductive freedom.

- Description: Saving clubs or stokvels have been around in many parts of the World, under different names, for many years and they have been instrumental in teaching people how to save. This research sets to investigate the possible use of stokvels as vehicles, channels or conduits for wealth accumulation among migrant population living in the inner city of Johannesburg. Participants’ contributions and the extent this translates into wealth accumulation among members were critically examined. Furthermore, the study explored whether gender plays any role in terms of stokvels membership and the reasons thereof. The hypothesis of this research was that incomes from stokvels contribute to wealth accumulation of migrants in the inner city of Johannesburg. This study used both quantitative and qualitative research methods to address the research questions and gather relevant data. The use of a mixed approach was adopted as it allows a deeper exploration of the different research objectives and questions of the study. Thematic content analysis was used to analyse the data. The findings of this study have revealed that there is a positive relationship between membership to stokvels and wealth accumulation. Moreover, trust and social capital were found to be pivotal in ensuring success of these groups in terms of who should be accepted into the group. However, many other factors, such as the level of education, the length of stay in South Africa and the marital status of participants could have an impact on wealth status of participants.

- Description: This study focussed on drafting a framework for Total Quality Management (TQM) for the South African Police Service (SAPS) in the Eastern Cape as a public non-profit organisation where quality of services is fast becoming a key organisational imperative. The early pioneers of Quality laid the foundation for Total Quality Management (TQM). The literature review highlighted that TQM has its origins in the manufacturing industry where it has a proven track record, and that the theory could be purposely adapted use by a specific industry, i.e. SAPS. This study extends the applicability of the TQM theory to the SAPS by using a mixed method approach to gather information by means of interviews and questionnaires. A combination of primary and secondary data was used in determining the Critical Success Factors (CSF). The Primary CSF’s were originally identified as Leadership, Strategic Management, Empowerment of employees, Teamwork, Continuous improvement, Customer satisfaction and Culture. The Secondary factors were identified as Communication, Training, Partnership development, Support structures, Systems and Resources, Systems thinking, Selfassessment, Processes; Elimination of barriers, Adoption of a Prevention approach and Change management. Data was analysed using frequency and other means, as well as correlation analysis. After the data was analysed two CSF’s were discarded, i.e. Training and Elimination of Barriers. The results show support for the applicability of the theory to the SAPS. Critical Success Factors were determined and a framework for implementation specifically for this industry, was presented. The study identified Leadership as the most important primary factor with the ultimate goal of meeting the quality expectations as defined by the customer.

- Description: Concentrating on the Katberg and Burgersdorp Formations, this research examined the sedimentary environments inter alia by conducting heavy mineral analysis, interpreting provenance and determining stratigraphic interrelationships of the two formations in the Tarkastad Subgroup (Beaufort Group, Karoo Supergroup) around the town of Whittlesea in the Eastern Cape Province of South Africa. It has been observed that the strata of the Katberg Formation are dominated by sandstones of a braided river system. On the other hand, the Burgersdorp Formation comprises mainly dark greyish-red mudstone, red shale with subordinate siltstone and red sandstone deposited on floodplains and channels of meandering rivers. The Katberg Formation becomes progressively less arenaceous to the north of the study area until it is virtually indistinguishable from the overlying Burgersdorp Formation. Dolerite dykes and sills that intruded the Karoo Supergroup disturbed and baked the sedimentary strata of the Tarkastad Subgroup as well as other Karoo successions. The Katberg formation is mostly found in elevated areas, commonly metamorphosed and capped by dolerite sills while the Burgersdorp is found in low lying areas and is less metamorphosed or not metamorphosed at all. Lithologies of the two formations and the Karoo dolerites have been geologically mapped and the interfingering relationship between the Burgersdorp and Katberg Formation is also shown on the map. Horizontal laminae, planar bedding and planar and trough cross-bedding characterise lithofacies in the two formations. The fossil hunt done during the course of the study did not yield any positive results in both formations. Initially, the pebbles from outcrops of the Katberg Formation in the East London area were described in hand specimen by Mountain (1939). This study took it further with petrographic- and modal analysis as well as grain size analysis for the sedimentary pebbles. Microscopic studies done on the rock samples collected in the study area revealed quartz and feldspar as the dominant constituents. Most of the feldspar is hazy as a result of dissolution and alteration to clays. Sparse sedimentary rock fragments and quartz overgrowths in some of the rocks and grains respectively, indicate phases of recycling from older sedimentary sources. Furthermore, the samples have a wide range of grain sizes, sorting, grain shapes and classification categories. Textural attributes of sediments such as mean grain size, sorting, skewness and kurtosis were used to characterise the nature of the transport processes and to reconstruct the depositional environment of the sediments. The sandstones of both the Katberg and Burgersdorp Formations are medium-grained and moderately sorted to moderately well sorted but the pebbles are very coarse- to coarse-grained. Deducing sediment provenance from the final product of a basin fill is anything but straight-forward because rocks break down and unstable minerals change during transportation along the pathways from source to basin and afterwards during diagenesis. Heavy mineral studies coupled with geochemical sandstone analysis were used to unravel the sources of sediments. Among the heavies found were opaque and non-opaque minerals which are highly resistant to weathering with zircon being the most dominant. The heavy mineral grains vary in shape from subround to angular-subround in shape. The integrated results of petrography, XRD, XRF and SEM/EDX were used to identify the source rock character and to evaluate the relative role of tectonics and climate in determining the geochemical composition of the Katberg and Burgersdorp sandstones. Sandstone composition was used to decipher the provenance and tectonic setting of source areas by standard triangular QtFL and QmFLt diagrams, tectonic setting discrimination diagrams and source rock composition diagrams to characterise the source rocks.
