The twelve contributions during this quantity symbolize the result of a 10 yr interdisciplinary workshop on "desert margins" - considering the geomorphological, geochemica, mineralogical, sedimentological, soil clinical characterisation of (semi-) deserts in Spain, Africa, Arabia and China. wilderness sediments and soils in addition to techniques and features in their formation are looked from diversified geoscientific views. the themes of study contain the improvement of barren region soils and landscapes, the formation of (alluvial) loess, swamp ores, fulgurites and floodout sediments and concentrate on the reconstruction of palaeoecological occasions and adjustments. A serious research of courting equipment rounds off the book.

And we clinicians can exhibit disorder to them by way of our scans, lay it out even on our genetic scrolls, and occasionally even indicate the errant nucleotide.

Because absolute dating of the paleosols was not possible in this study, their relative ages were estimated by comparing soil type and degrees of weathering. Interpretations incorporated results from geomorphological and archaeological investigations, which were carried out at the same locations, and from previous paleopedological and geomorphological investigations in the Grand Erg de Bilma, adjacent to the Ténéré, and the Sahelian zone of East Niger, carried out by Grunert (1988), Völkel (1988, 1989) and Völkel and Grunert (1990).

Many of the extended paleo-lakes display multiple repetition of the swamp-ore beds from higher relief positions of flat-shore areas towards the paleolake basin. They always strictly follow the contour lines (Photo 2). 2 Swamp-ore deposits at selected study sites The spatial distribution and the morphological characteristics of swamp-ores at two study sites are presented in order to demonstrate the variability in morphological characteristics and local peculiarities, which can be used for a genetical and paleo-climatic interpretation.
