CL-imaging and ion microprobe dating of single zircons from a high-grade rock from the Central Zone, Limpopo Belt, South Africa: Evidence for a single metamorphic event at ∼2.0Ga
Autor: Hassina Mouri, Martin J. Whitehouse, S. A. de Waal, G. Brandl, M. Guiraud
Publikováno v: Journal of African Earth Sciences. 50:111-119
The combination of ion microprobe dating and cathodoluminescence (CL) imaging of zircons from a high-grade rock from the Central Zone of the Limpopo Belt were used to constrain the age of metamorphic events in the area. Zircon grains extracted from a

The Lindeques Drift and Heidelberg Intrusions and the Roodekraal Complex,Vredefort, South Africa: comagmatic plutonic and volcanic products of a 2055 Ma ferrobasaltic magma
Autor: Ian T. Graham, S. A. de Waal, Richard Armstrong
Publikováno v: South African Journal of Geology. 109:279-300
The Lindeques Drift and Heidelberg Intrusions and the volcanic Roodekraal Complex belong to a high-Ti mafic igneous suite (HITIS) that was emplaced in the Kaapvaal Craton as km-sized bodies, to the north and north-east of the Vredefort impact structu

New U–Pb SHRIMP zircon age for the Schurwedraai alkali granite: Implications for pre-impact development of the Vredefort Dome and extent of Bushveld magmatism, South Africa
Autor: Ian T. Graham, Richard Armstrong, S. A. de Waal
Publikováno v: Journal of African Earth Sciences. 43:537-548
The Schurwedraai alkali granite is one of a number of prominent ultramafic-mafic and felsic intrusions in the Neoarchaean to Palaeoproterozoic sub-vertical supracrustal collar rocks of the Vredefort Dome, South Africa. The alkali granite intruded the

First occurrence of the rare ‘corundum + quartz’ assemblage in the high-grade zone from the Namaqualand Metamorphic Complex, South Africa: evidence for higher-P, T metamorphism?
Autor: Hassina Mouri, M. Guiraud, J.-R. Kienast, Marco A.G. Andreoli, S. A. de Waal
Publikováno v: Mineralogical Magazine. 67:1015-1021
We report in this paper the first occurrence of the rare assemblage corundum + quartz in the high-grade metamorphic zone in the core of the Namaqualand Metamorphic Complex (NMC) (South Africa). The magnetite-bearing rocks hosting the corundum-quartz

Magmatic Ni-Cu versus PGE deposits: Contrasting genetic controls and exploration implications
Autor: Wolfgang D. Maier, Chusi Li, S. A. de Waal
Publikováno v: South African Journal of Geology. 104:309-318
Both Ni-Cu and PGE deposits are associated with mafic and ultramafic rocks, but the former often occur in dynamic magmatic systems such as lava channels and magma conduits whereas the later occur in larger layered intrusions. The contrasting modes of
