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 ...
Origin and palaeo-environments of calcareous sediments' in the Moshaweng dry valley, Southeast Botswana
(John Wiley & Sons, Ltd. http://www3.interscience.wiley.com/journal/117935722/grouphome/home.html, 2002)
Quaternary sedimentation in the Moshaweng dry valley of southeastern Botswana is evaluated on the basis of geomorphological evolution and sedimentological analyses. Stratigraphic evidence reveals an 'upper surface (1095 ...
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 ...
Genesis of sediment-hosted stratiform copper–cobalt deposits, central African Copperbelt
(Elsevier www.elsevier.com/locate/jafrearsci, 2005)
The Neoproterozoic central African Copperbelt is one of the greatest sediment-hosted stratiform Cu–Co provinces in the world, totalling
140 Mt copper and 6 Mt cobalt and including several world-class deposits (P10 Mt ...
Shallow seismic refraction and magnetic studies at Lake Ngami, The Okavango Delta, Northwest Botswana
(Elsevier www.elsevier.com/locate/jafrearsci, 2007)
A seismic refraction analysis was carried out on data acquired on an 8.5 km profile at Lake Ngami, NW Botswana, to determine the
structure and stratigraphy underlying the lake. The seismic spread comprised a 48-channel ...
Ages of detrital zircon grains from Neoproterozoic siliciclastic rocks in the Shakawe area: implications for the evolution of Proterozoic crust in northern Botswana
(Geological Society of South Africa. http://sajg.geoscienceworld.org/, 2000-06)
The Precambrian rocks of northern Botswana comprise poorly exposed igneous complexes, high-grade metamorphic
rocks, as well as sedimentary sequences including mainly siliciclastic and carbonate rocks. New U-Pb SHRIMP
data ...
Sulphur isotope constraints on formation conditions of the Luiswishi ore deposit, Democratic Republic of Congo (DRC)
(Elsevier www.elsevier.com/locate/jafrearsci, 2005)
Luiswishi is a Congo-type Neoproterozoic sediment-hosted stratiform Cu–Co ore deposit of the Central Africa Copperbelt, located
northwest of Lubumbashi (DRC). The ores form two main Cu–Co orebodies hosted by the Mines ...
Gravity evidence for a larger Limpopo Belt in southern Africa and geodynamic implications
(Royal Astronomical Society. http://www.wiley.com/bw/journal.asp?ref=0956-540X&site=1, 2002)
The Limpopo Belt of southern Africa is a Neoarchean orogenic belt located between two older Archean provinces, the Zimbabwe craton to the north and the Kaapvaal craton to the south. Previous studies considered the Limpopo ...
Origins of strandline duricrusts around the Makgadikgadi Pans (Botswana Kalahari) as deduced from their chemical and isotope composition
(Elsevier www.elsevier.com/locate/sedgeo, 2009)
Trace elements togetherwith some O and C isotope analysiswere undertaken on duricrust strandline deposits in
the palaeo-Makgadikgadi sub-basin (PMSB) to provide insight into palaeo-climatic conditions through the
interpretation ...
Characterization of enriched lithospheric mantle components in ∼2.7 Ga Banded Iron Formations: An example from the Tati Greenstone Belt, Northeastern Botswana
(Elsevier www.elsevier.com/locate/precamres, 2009)
Major and trace element, samarium (Sm)–neodymium (Nd) and lead (Pb) isotopic analyses of individual
mesobands of five Banded Iron Formations (BIFs) and associated volcanic and sedimentary rocks from
the Neoarchean Tati ...
