The crystal and molecular structure of the bis(4-N, N1-dimethylaminopyridine) solvate of disalicylicacidatobis(nitrotodioxouranium)(VI)

  • Authors: Nassimbeni, L R , Rodgers, Allen L , Haigh, John M
  • Date: 1976
  • Language: English
  • Type: text , Article
  • Identifier: vital:6415 , http://hdl.handle.net/10962/d1006526
  • Description: The structure of the title compound [(C7H4NO8U)(C7H11N2)]2 has been determined by Patterson and Fourier methods from single crystal X-ray diffraction data collected on a four-circle diffractometer. Full-matrix least-squares refinement yielded a final conventional R of 0.041 for 2189 reflections. The complex crystallizes in the space group P with a = 11.004(5), b = 9.981(5), c = 9.928(5) Å, α = 119.6(3), β = 107.7(3), γ = 81.9(3)°, Dm = 2.17, Dc = 2.173g cm−3. The structure is dimeric. The uranium atoms are eight-coordinate and are bridged via centrosymmetrically related carboxylic oxygen atoms. The nitrate group is bidentate and the average U---O (ligand) distance is 2.463 Å. Hydrogen bonding of the type N---HO links two dimethyl-aminopyridine molecules to the dimer.

The Lüderitz alkaline province, South West Africa, III: the Pomona and Drachenberg Syenite Complexes

  • Authors: Marsh, Julian S
  • Date: 1976
  • Language: English
  • Type: text , article
  • Identifier: http://hdl.handle.net/10962/132984 , vital:36915 , https://hdl.handle.net/10520/AJA10120750_2853
  • Description: The Pomona ring complex consists of several intrusive masses of syenitic magma that define a differentiation trend towards silica oversaturation. Volume relations, sequence of intrusion, and broad chemical characteristics are consistent with the syenites being derived by feldspar fractionation from an immediate syenitic parent. A plug of nepheline syenite and tinguaite dykes indicate the availability of silica-undersaturated magma generally in the Luderitz Province.

  • Language: English
  • Type: Article , text
  • Identifier: vital:6373 , http://hdl.handle.net/10962/d1006077
  • Description: Crystals of the title compound are monoclinic with a= 8.314 (5), b= 22.723 (9), c= 12.589 (6) A, /3= 123.0 (2t, Z=4, space group P2dc. The structure was determined by Patterson and Fourier methods and refined by full-matrix least squares to a final R of 0.030 for 2043 independent reflexions. The U atom has pentagonal bipyramidal coordination and the N-methylacetylacetoneamine is bonded to U via O. There are two intramolecular N-H. . .0 hydrogen bonds which govern the geometry of the adduct molecule.

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 15 , A study of the eels which have been referred to Muraenesox McClelland clarifies taxonomic confusion in this group and shows it to contain three genera and seven species. M cinereus (Forsskål, 1775) occurs from the Red Sea across the Indian Ocean northwards to Japan . M. bagio (Hamilton, 1822) has a wider distribution from South Africa throughout the Indo-west Pacific north to Japan and south to Sydney. Congresox Gill is revived for C. talabon (Cuvier, 1829) and C. talabonoides (Bleeker, 1853) both of which occur in the central Indo-west Pacific. Cynoponticus Costa is represented by C. savanna (Bancroft, 1831) in the West Atlantic, C. ferox Costa, 1845 in the East Atlantic and Mediterranean and C. coniceps (Jordan and Gilbert, 1881) in the central East Pacific.

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 14 , This is in essence a checklist of the marine fishes occurring in the estuarine and coastal waters of southern Africa from the Kunene River in the west to Beira in the east. Deep sea fishes occurring below 200 metres or 100 fathoms are not included. The freshwater fishes from the Zambezi southwards will be published in Part 2. The scientific names, their spelling, authors and dates, have been carefully checked and brought into line with the most recent revisions available. However, the tremendous outpouring of scientific papers will make some scientific names obsolete even while this checklist is being printed. Also there will continue to be additions to the fauna and this, the first list to be published, must be regarded as a foundation on which subsequent lists can be based.

Aenigmatite stability in silica-undersaturated rocks

  • Authors: Marsh, Julian S
  • Date: 1975
  • Language: English
  • Type: text , article
  • Identifier: http://hdl.handle.net/10962/132942 , vital:36911 , https://doi.org/10.1007/BF00373333
  • Description: Aenigmatite is common in many trachytes, phonolites and agpaitic nepheline syenites. Petrographic evidence suggests that the aenigmatite in these rocks arises by the reaction of Ti-magnetite with a peralkaline silica-undersaturated liquid, and it is postulated that a no-oxide field, where aenigmatite is stable, exists in alkaline undersaturated magmas.

The Klinghardt phonolites, South West Africa: Tertiary volcanism in western southern Africa

  • Authors: Marsh, Julian S , Lock, B E
  • Date: 1975
  • Language: English
  • Type: text , article
  • Identifier: http://hdl.handle.net/10962/70164 , vital:29627
  • Description: Over 1OO phonolite bodies of mid-Tertiary age occur in the Klinghardt Mountains, 1OO km SE of Luderitz in Southern South West Africa the only published account of these rocks is that of Kaiser (1926) who gives a generalized map and describes briefly the mode of occurrence and petrography of the phonolites. The phonolite bodies are concentrated in an area roughly 8OO km2 and constitute an excellent example of an areal volcanic field (Rittmann, 1962), i.e. the activity occurred at a number of vents spread over a wide area and in most cases only a single eruptive episode took place at each vent.

The Luderitz Alkaline Province, South West Africa I: descriptive petrology of the Granitberg Foyaite Complex

  • Authors: Marsh, Julian S
  • Date: 1975
  • Language: English
  • Type: text , article
  • Identifier: http://hdl.handle.net/10962/132951 , vital:36912
  • Description: The Granitberg foyaite complex is one of three known alkaline igneous complexes, which, together with a dyke swarm, constitute the Liüderitz Alkaline Province of Lower Cretaceous age. The near-circular complex is emplaced into dolomites and sandstones of the Bogenfels Formation. A large fragment of these sedimentary rocks, originally forming the roof of the intrusion, is preserved in the centre of the complex.

The Luderitz Alkaline Province, South West Africa II: metasomatism and assimilation in the contact aureole of the Granitberg Foyaite Complex

  • Authors: Marsh, Julian S
  • Date: 1975
  • Language: English
  • Type: text , article
  • Identifier: http://hdl.handle.net/10962/132963 , vital:36913
  • Description: Reactions between the Outer Foyaite magma of the Granitberg Complex and the sedimentary country rocks are striking. At sandstone contacts the magma has assimilated quartz-rich sedimentary material and a suite of pulaskites, peralkaline nordmarkites, and peralkaline granites have been generated by a complex process involving both assimilation and crystal fractionation.
