Paleoproterozoic intraplate magmatism and basin development on the Kaapvaal Craton: Age, paleomagnetism and geochemistry of ~1.93 to ~1.87 Ga post-Waterberg dolerites
Richard E. Hanson,Wulf A. Gose,James L. Crowley,Jahandar Ramezani,Samuel A. Bowring,D. Bullen,R.P. Hall,James A. Pancake,Joshua Mukwakwami +8 more
TL;DR: Pb baddeleyite crystallization ages of ~1927 and ~1879 to ~1872 Ma for dolerite sills intruding the Waterberg Group in Botswana and South Africa were reported in this article.
Journal ArticleDOI

Richard E. Hanson,R. E. Harmer,Thomas G. Blenkinsop,D. Bullen,Ian W. D. Dalziel,Wulf A. Gose,R.P. Hall,Ali B Kampunzu,Roger Key,Joshua Mukwakwami,Hubert Munyanyiwa,J. A. Pancake,Emily K. Seidel,S. E. Ward +13 more
TL;DR: The Kalahari Craton was initially stabilized following cessation of Palaeoproterozoic orogenesis in southern Africa at ca. 1.4-1.8 Ga as discussed by the authors.
Journal ArticleDOI
Plume magmatism and crustal growth at 2.9 to 3.0 Ga in the Steep Rock and Lumby Lake area, Western Superior Province
TL;DR: The greenstone belts of the western Superior Province are predominantly 2.78 to 2.69 Ga and provide evidence of oceanic and arc volcanism during the accretionary phase of development of the Superior Province as mentioned in this paper.
Journal ArticleDOI
Geochemistry and petrogenesis of mafic sills in the 1.1 Ga Umkondo large igneous province, southern Africa
TL;DR: The Mesoproterozoic Post-Waterberg sills A (MPWA sills) are characteristically LREE enriched with relatively unfractionated HREEs, and with normalised incompatible element profiles similar to modern island arc andesites as mentioned in this paper.
Journal ArticleDOI
Evidence for a high Mg andesitic parental magma to the East and West satellite dykes of the Great Dyke, Zimbabwe: a comparison with the continental tholeiitic Mashonaland sills
TL;DR: One of the most significant mafic intrusive events in the Zimbabwe Craton was the emplacement of the Great Dyke layered ultramafic-mafic complex and its two parallel dykes at the end of the Archaean (∼2.6 Ga) as discussed by the authors.
