(Wiley-Blackwell, 2011-04)Volcanic terrains such as magmatic arcs are thought to display the most complex surface environments on Earth. Ancient volcaniclastics are notoriously difficult to interpret as they describe the interplay between a single ...
-
(Geological Society of South Africa, 2010)The Johannesburg Dome (JD) in the central Kaapvaal Cratoti (KC) is dominated by granitoid rocks of the tonalite-trondhjemite- KniiKKliorite (TTG) series. Ba.sed on modal analysis as well as a major atid trace element ...
-
(Springer, 2011-01)Due to lack of sufficient historical data of tsunami in the Makran subduction zone (MSZ) at the northwestern Indian Ocean, a probabilistic method is employed to assess the tsunami hazards in this region. The method employs ...
-
(Elsevier, 2011-01)SHRIMP dating of titanite from metasyenites in the Central Zone of the Limpopo Belt yields a mean 207Pb/206Pb age of 2010.3 ±4.5 Ma calculated from 23 analyses. This age, combined with petrographic and field observations, ...
-
(Springer, 2010-04)Research into a new method for separating palladium from rhodium, based on radiochemical principles, necessitated a re-investigation of the Gmelins Handbuch data indicating that Rh has allotropes. Two independent and ...
-
(South African Institution of Civil Engineering, 2010-10)Research was done to determine whether a relationship can be established between index testing and CBR (California Bearing Ratio) results. The process involved compiling a database of test results for a range of rock ...
-
(Southern African Institute of Mining and Metallurgy, 2009-10)The characterization of platinum group minerals (PGMs) from concentrator flotation circuits provides valuable information towards understanding PGM recovery under given milling and flotation conditions. Additional ...
-
(Geological Society of South Africa, 2009)Remnants of diamond-bearing fluvial gravels of Cretaceous age have been preserved on the Ghaap Plateau north-west of Reivilo at 1455 in above sea level. The alluvial deposit contains well preserved fossil woods representing ...
-
(Muséum d'histoire naturelle de la Ville de Genève, 2009-06)Brachiopods were affected strongly by the Early Toarcian mass extinction within the Northern Caucasus, which at that time was a large region on the northern margin of the Neo-Tethys Ocean. However, their decline preceded ...
-
(Academy of Science of South Africa, 2009-09)Complex structures in the sandstones of the Lower Jurassic aeolian Clarens Formation (Karoo Supergroup) are found at numerous localities throughout southern Africa, and can be assigned to five distinct architectural groups: ...
-
(Current Science Association, 2009-10)Worldwide, chromitites compared to associated silicate rocks, are commonly characterized with elevated platinum group element (PGE) contents. The two prominent working chromite mines, Bangur and Baula in Orissa, were sampled ...
-
(Elsevier, 2009)The sparse Archean fossil record is based almost entirely on carbonaceous remnants of microorganisms cellularly preserved due to their early post-mortem silicification. Hitherto as an exception, sedimentary carbonate rocks ...
-
(Elsevier, 2009)A single metapelitic sample from the Verbaard locality, near Messina was investigated in order to construct a P–T path and moreover, highlight pertinent contradictions in the current P–T database. Interpretations based on ...
-
(Elsevier, 2009)Global tracing of the key surfaces of Triassic deposits may contribute significantly to the understanding of the common patterns in their accumulation. We attempt to define synthems – disconformity-bounded sedimentary ...
-
(Elsevier, 2008)Published literature argues that the Limpopo Belt can be subdivided into three zones, each with a distinctive geological character and tectono-metamorphic fingerprint. There are currently two contrasting schools of thought ...
-
(Geological Society of South Africa, 2008)Gold-rich alloys with variable amounts of Pd from the Merensky Reef, Bushveld Complex, are characterized by a range of finely dispersed inclusions. The small sizes of these inclusions (median of 1,85 µm) make fully ...
-
(Geological Society of South Africa, 2008-09)The oxygen content of cordierite was analysed in 30, well-characterised samples, using electron probe micro-analysis (EPMA). The major elements were assumed to be stoichiometric and therefore any remaining oxygen from the ...
-
(Geological Society of South Africa, 2008)Two new assemblages (farms Christina and Moorfield) of plant fossils belonging to the Glossopterid flora are described from the northeastern part of the Main Karoo basin, within the Late Permian Normandien Formation, ...
