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 ...
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 ...
Work in Thermodynamics
(Chemic Publishing Co., http://www.asianjournalofchemistry.com/, 2006)
The expression for mechanical work obtained in the expansion of a gas commonly used in physical chemistry textbooks is critically examined. The mathematical form of the first law of thermodynamics is arrived at by a procedure ...
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 ...
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 ...
An overview of the geology and major ore deposits of Central Africa: Explanatory note for the 1:4,000,000 map ‘‘Geology and major ore deposits of Central Africa’’
(Elsevier www.elsevier.com/locate/jafrearsci, 2006)
This paper is prepared within the frameworks of IGCP Project 470 and the associated BRGM scientific project ‘‘Africa 1999–2004’’ to
accompany the 1:4,000,000 scale map ‘‘Geology and major ore deposits of Central Africa, ...
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 ...
Nanoindentation measurements of the mechanical properties of polycrystalline Au and Ag thin films on silicon substrates: Effects of grain size and film thickness
(Elsevier, 2006)
This paper presents the results of nanoindentation experimental studies of the contact-induced deformation in Au and Ag thin films. The paper
examines the effects of film thickness and substrate deformation restraint on ...
Volumetric Properties of (Difurylmethane + Alkan-1-ol) Binary Mixtures at 298.15 K
(Journal of Solution Chemistry., 2006)
Densities (ρ) of the binary systems of {difurylmethane+(ethanol or propan-1-
ol or butan-1-ol or pentan-1-ol or hexan-1-ol)} have been measured with an Anton Paar
DMA 4500 vibrating-tube densimeter over the entire ...
