The Karoo triple junction questioned: evidence from Jurassic and Proterozoic 40Ar/39Ar ages and geochemistry of the giant Okavango dyke swarm (Botswana)
(Elservier www.elsevier.com/locate/epsl, 2004)
The lower Jurassic Karoo–Ferrar magmatism represents one of the most important Phanerozoic continental flood basalt
(CFB) provinces. The Karoo CFB province is dominated by tholeiitic traps and apparently radiating giant ...
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 ...
Lithostratigraphic position and petrographic characteristics of R.A.T. (‘‘Roches Argilo-Talqueuses’’) Subgroup, Neoproterozoic Katangan Belt (Congo)
(Elsevier www.elsevier.com/locate/jafrearsci, 2005)
The Neoproterozoic Katangan R.A.T. ("Roches Argilo-Talqueuses") Subgroup is a sedimentary sequence composed of red massive
to irregularly bedded terrigenous-dolomitic rocks occurring at the base of the Katangan succession ...
The Neoproterozoic Mwashya–Kansuki sedimentary rock succession in the central African Copperbelt, its Cu–Co mineralisation, and regional correlations
(Elsevier www.elsevier.com/locate/gr, 2007)
Rocks of the Neoproterozoic Mwashya Subgroup (former Upper Mwashya) form the uppermost sedimentary unit of the Roan Group. Based on
new field and drill hole observations, the Mwashya is subdivided into three formations: ...
Cryptic indicators of provenance from the geochemistry of the Okavango Delta sediments, Botswana
(Elsevier www.elsevier.com/locate/sedgeo, 2005)
The siliciclastic sediments of the Okavango inland Delta of northwest Botswana have a modal composition of quartz arenites
and result from a complex history, including transport by river and deposition in a nascent rift ...
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 ...
Rainfall interpolation using a remote sensing CCD data in a tropical basin – A GIS and geostatistical application
(Elsevier, www.elsevier.com/locate/pce, 2007)
This paper is aimed at developing a geostatistical model to improve interpolated annual and monthly rainfall variation using remotely-
sensed cold cloud duration (CCD) data as a background image. The data set consists of ...
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 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 ...
The Okavango giant mafic dyke swarm (NE Botswana): its structural significance within the Karoo Large Igneous Province
(Elsevier www.elsevier.com/locate/jsg, 2005)
The structural organization of a giant mafic dyke swarm, the Okavango complex, in the northern Karoo Large Igneous Province (LIP) of
NE Botswana is detailed. This N1108E-oriented dyke swarm extends for 1500 km with a ...
