Geological interpretations from the PGE distribution in the Bushveld Merensky and UG2 chromitite reefs
It is well known that the platinum group element (PGE) mineralization in the Merensky and UG2 chromitite reefs is restricted to a very narrow vertical interval of rocks (Wagner, 1929). In the UG2 chromitite there is essentially no PGE above or below the chromitite layer that rarely exceeds 1 m thick. In the Merensky Reef a very large proportion of the PGE is confined within 1 m vertically in ma...
متن کاملEmplacement and Crystallization Time for the Bushveld Complex
The Bushveld Complex formed by the crystallization of successive basaltic magmatism may be of the order of several million years. For example, the Columbia River Basalts (Hooper, injections of magma, which were sufficiently closely spaced in time that each previous magma had not cooled and differentiated 1988) were erupted in the period 17–12 Ma, with minor eruptions for a further 5 my, althoug...
متن کاملThe centenary of the discovery of platinum in the Bushveld Complex (10 November, 1906)
The story of Dr. Hans Merensky’s discoveries of the platinum-rich pipes and the Merensky Reef itself in 1924 have been well documented (Cawthorn, 1999; Scoon and Mitchell, 2004, and references therein), but the events that preceded it have not been summarized. In the probable centenary year of the first report of platinum in the Bushveld it is appropriate to review the events between 1906 and 1...
متن کاملPetrogenetic modelling of strongly residual metapelitic xenoliths within the southern Platreef, Bushveld Complex, South Africa
Xenoliths of quartz-absent Fe-rich aluminous metapelite are common within the platinum group element-rich mafic ⁄ultramafic magmatic rocks of the Platreef. Relative to well-characterized protoliths, the xenoliths are strongly depleted in K2O and H2O, and have lost a substantial amount of melt (>50 vol.%). Mineral equilibria calculations in the NCKFMASHTO system yield results that are consistent...
متن کاملIn the Case of Maden Complex, Geochemical Constraints on the Origin and Tectonic Implication of Eocene Magmatism in SE Turkey
The origin and geodynamic setting of the Maden Complex, which is situated in the Bitlis–Zagros Suture Zone in the Southeast Anatolian Orogenic Belt, is still controversial due to lack of systematic geological and geochemical data. Here we present new whole rock major–trace–rare earth element data from the Middle Eocene volcanic rocks exposed in Maden Complex and discuss their origin in the ligh...
