Soil heavy metal concentration patterns at two speed zones along the Gaborone-Tlokweng border post highway, Southeast Botswana
(JASEM http://www.ajol.info/index.php/jasem/article/view/43693/27216, 2006-06)
Since 1988 Botswana has been experiencing an unprecedented increase in vehicular traffic which
is suspected to be having contamination effects on soils along heavily used roads in the country. This study aimed at
understanding ...
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 ...
Investigation of sustainability of rain-fed agriculture through soil moisture modeling in the Pandamatenga Plains of Botswana
(Elsevier Ltd. http://www.elsevier.com/wps/find/journaldescription.cws_home/413/description#description, 2006)
The agricultural economic sector of Botswana is limited mainly to range resources-based livestock and pockets of arable farming
based on rainfall and limited irrigated agriculture at several places. In this study agricultural ...
Towards a theoretical exploration of the differential urbanisation model in Sub-saharan Africa: The Botswana case
(Blackwell Publishing Ltd, http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1467-9663, 2006)
This paper investigates the extent to which the differential urbanisation model is applicable to
Botswana by using empirical data obtained from periodic censuses, supportive documentary
information and observations from ...
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 ...
