A ca. 200Ma hiatus between the Lower and Upper Transvaal Groups of southern Africa: SHRIMP U–Pb detrital zircon evidence from the Segwagwa Group, Botswana: Implications for Palaeoproterozoic glaciations
(Elsevier B.V. www.elsevier.com/locate/epsl, 2006)
The Segwagwa Group of southeastern Botswana, a correlate of the Pretoria Group of the Transvaal Supergroup of South Africa,
consists of a major sequence of siliciclastic sedimentary rocks, minor carbonates and basaltic ...
The Okwa basement complex, western Botswana: U–Pb zircon geochronology and implications for Eburnean processes in southern Africa
(Elsevier Ltd. www.elsevier.com/locate/jafrearsci, 2006)
The Okwa Basement Complex crops out at the northwestern edge of the Kaapvaal craton within the Okwa Inlier, an isolated exposure
of Precambrian basement in the Kalahari Desert. New U–Pb zircon dating was performed on all ...
Petrology and geochemistry of the Neoproterozoic Nguba and Kundelungu Groups, Katangan Supergroup, southeast Congo: Implications for provenance, paleoweathering and geotectonic setting
(Elsevier www.elsevier.com/locate/jafrearsci, 2006)
The Nguba and Kundelungu Groups constitute the middle and upper parts of the Neoproterozoic Katangan Supergroup, respectively,
and consist of conglomerates, sandstones, mudrocks and carbonates. During deposition, the ...
The Mesoproterozoic Irumide belt of Zambia
(Elsevier www.elsevier.com/locate/jafrearsci, 2006)
The Mesoproterozoic Irumide belt is a northeast-trending structural province stretching from central Zambia to the Zambia–Tanzania
border and northern Malawi. Mesoproterozoic and Neoproterozoic transcurrent shear zones ...
Use of the geochemical and biological sedimentary record in establishing palaeo-environments and climate changein the Lake Ngami basin, NW Botswana
(Elsevier, www.sciencedirect.com, 2006)
Sediment samples from a continuous 4.6m profile in the dry bed of Lake Ngami in NW Botswana were analysed for geochemistry and
dated using both 14C and TL methods. Certain units in the profile were found to be diatom rich ...

(Elsevier www.elsevier.com/locate/epsl, 2006)
The Segwagwa Group of southeastern Botswana, a correlate of the Pretoria Group of the Transvaal Supergroup of South Africa, consists of a major sequence of siliciclastic sedimentary rocks, minor carbonates and basaltic to ...
Basement control on dyke distribution in Large Igneous Provinces: Case study of the Karoo triple junction
(Elsevier www.elsevier.com/locate/epsl, 2006)
Continental flood basalts consist of vast quantities of lava, sills and giant dyke swarms that are associated with
continental break-up. The commonly radiating geometry of dyke swarms in these provinces is generally ...
Mesoproterozoic rocks of Namibia and their plate tectonic setting
(Elsevier www.elsevier.com/locate/jafrearsci, 2006)
Two main Mesoproterozoic provinces occur in southern Namibia: (1) The high-grade Namaqua Metamorphic Complex (NMC) composed
of a supracrustal sedimentary succession and interpreted as a passive margin sequence in the west ...
