- Description: Archaeopteris notosaria sp. nov. based on one fertile and numerous sterile leafy branches is described from the Grahamstown By-Pass locality, Witpoort Formation (Witteberg Group) Upper Devonian, and represents the first unequivocal record of the genus in southern Africa. This occurrence is used, in its palaeogeographical context, to support the suggestion that climatic gradients in Late Devonian times were less steep than they are at present.

- Description: The first record of Palaeozoic charophytes from southern Africa allows the establishment of two new genera to which are assigned four new species, Octochara crassa, O. gracilis. Hexachara setacea, and H. riniensis. Each species is represented by both vegetative and reproductive structures and suggested reconstructions are presented. Associated plant and animal remains, and the sedimentology and geochemistry of the containing rocks indicate that the charophytes probably grew in the shallow parts of a brackish coastal lagoon.

From the base up, the Klipriviersberg Group consists of the Westonaria, Alberton, Orkney, Jeannette, Loraine, and Edenville formations, with a maximum combined thickness of 1–8 km. Samples were obtained from several borehole cores in the Klerksdorp goldfield close to the type area of the Klipriviersberg Group.

- Description: Analyses of samples from a weathering profile on Karoo dolerite allow elements to be divided into three groups depending on their behaviour. Si, K, Na, Mg, Ca, Sr, Ba and V are mobilized and removed from weathered products. Fe, Al. Ti, Zr, Hf, Zn, Cu, Sc, Co and Ni are immobile. REE, Y, and to a lesser extent Cr, are mobile and redistributed within the profile without a net loss of these elements from the profile. Large positive Ce anomalies are developed in oxidized weathered products by preferential leaching of the other REE's. Negative Ce anomalies and REE enrichment is a feature of less altered dolerite.

- Description: The Etendeka Formation volcanics consist of a bimodal association of basalts and quartz latites. Forty three new whole rock oxygen isotope analyses are reported for all the major magma types. All the rocks except a minor suite of dolerites have higher δ18O values than normal mantle. The basic rocks (average of 29=8.8‰) have significantly different δ18O to the acid rocks (average of 10=14.4‰). These data are apparently consistent with previously published petrogenetic models, which propose that the basalts were affected by crustal contamination and that the quartz latites are crustally derived.

- Description: Al/Cr atomic ratios of coexisting spinellids and ortho- and clinopyroxenes show a pattern of sympathetic variation that persists through ultramafic rocks of layered mafic complexes of upper-crustal type, Alpine complexes, and the nodules found in kimberlites and alkaline basalts. Simple expressions are empirically derived to link (Al/Cr) orthopyroxene and (Al/Cr)spinel ratios in putatively equilibrated rocks. Equivalence of spinel compositions in shallow layered complexes and kimberlite nodules of deep-seated origin negates direct crystallochemical control of Al/Cr ratios of spinels by pressure.

For example, in the Bushveld Complex in South Africa, abrupt increases in initial 87Sr/86Sr ratios occur at the UG-2 and Merensky pegmatoid (or ‘reef’) horizons, both of which are exploited for PGEs. We report here the results of a detailed Sr-isotope study across the Merensky unit and its immediate foot- and hangingwall-rocks which, when considered together with new ideas on processes operating in magma chambers3–5, suggest that magma mixing and post-cumulus infiltration of liquids displaced from below were important during crystallization of the Merensky pegmatoid.

- Description: Newspaper article: "Cycads, South Africa's precious living fossils, are being stolen and sold to smart-set gardeners in South Africa, Japan and the United States reports The Daily News. Plants of one rare species, Encephelatus Woodii, have been offered for sale in the United States for R5 000. Botanists say cycads sell for R26 a centimeter overseas, so that a waist-high plant fetches about R2 500. Cycads are very slow-growing. Plants germinated 12 years ago at the Natal Botanical Gardens have a stem the size of a small football. Hence plants of a reasonable size may be hundreds of years old, while the rootstock from which the plants grow may be thousands of years old. There are 28 species in South Africa and seven occur in Natal. They are known in Afrikaans as Broodboom (bread tree) because Hottentots were said to make bread from the pith, after it had been left to rot for two months. A spokesman for the Natal Parks Board said the authorities could not prevent exploitation. Convictions for removing protected plants were difficult to obtain as it was almost impossible to prove where the plants came from unless the culprits were caught red-handed. When found to be in illegal possession, plants ere confiscated and planted out.Miss Jane Baxter, Natal Parks Board public relations officer, dwarfed by a giant cycad, Encephelatus Natalensis. This fine plant is thought to be between 150 and 200 years old. The Daily News. S. A. Digest. 8 June 1979."
