Concentrations of sulfur and carbon, and isotopic compositions of sulfur were determined in sedimentary rocks from a section across the terrestrial Permian^Triassic (P^Tr) boundary in the northern Karoo Basin, South Africa. High concentrations of sulfide produced by sulfate-reducing bacteria were found in the sedimentary rocks at and just below the perceived P^Tr boundary. The ratios of organic...

The present article is a review of a palaeobiogeographic analysis of Jurassic Ostracods from East Africa, India and Madagascar and includes also some general remarks on palaeobiogeography, biodiversity and Ostracod ecology.The palaeobiogeographic study shows the high significance of this microfossil group for the reconstruction of palaeogeographic processes, particularly plate tectonic developm...

Salt consumption is high in Africa and the continent also shares the greatest burden of hypertension. This study examines salt-related knowledge, attitude and self-reported behaviours (KAB) amongst adults from two African countries-Ghana and South Africa-which have distributed different public health messages related to salt. KAB was assessed in the multinational longitudinal World Health Organ...

The massive sulphide deposit at Kantienpan Cu-Zn mine is hosted by volcano sedimentary succession known as the Areachap Group, in the eastern part of Namaqua Metamorphic Province, South Africa. The deposits were affected by a complex deformation and metamorphic history and represent examples of upper amphibolite to granulite grade metamorphosed volcanic-hosted m...

The Montagne Noire located in the southern part of French Massif Central represents northern South-Variscan Foreland. It is subdivided into three parts. granite-migmatite Axial Zone dome surrounded by non- or weakly metamorphosed Paleozoic sedimentary series. Both and flanks are deformed km-scale, south to southeast facing recumbent folds thrusts sheets. Raman Spectroscopy Carbonaceous Material...

Seismic reflection profiles, drill-hole data, and geologic maps delimit the form of normal faults and Tertiary sedimentary rocks in the southern half of the Cache Valley basin in northern Utah. Dips of faults and sedimentary rocks were estimated from time-migrated reflection profiles by using the stacking velocities for the data. At the southern end of the basin, the East Cache fault zone is li...

CIOs in Hungary, Romania, and South Africa (SA) are today overcoming disadvantages that their firms suffered during decades of closed national markets. This paper reports on a series of interviews conducted with CIOs in these developing countries focusing on national and organizational strategies used to prepare for international competition and globalization. They achieved competitiveness by i...

THE problem of salt deposits in a present deep-sea basin has been discussed recently in the case of the Atlantic Oceanl. In this article we present new data on the salt layer in the Western Mediterranean Basin. In the Balearic Basin and the Ligurian Sea, anticline structures and dornes disturbing the upper part of the sedimentary cover have been reported by Alinat and Cousteauz, Menard et aL3, ...
