The twelve contributions in this volume represent the results of a ten year interdisciplinary workshop on "desert margins" - concerned with the geomorphological, geochemica, mineralogical, sedimentological, soil scientific characterisation of (semi-) deserts in Spain, Africa, Arabia and China. Desert sediments and soils as well as processes and characteristics of their formation are regarded from different geoscientific perspectives. The subjects of research include the development of desert soils and landscapes, the formation of (alluvial) loess, swamp ores, fulgurites and floodout sediments and focus on the reconstruction of palaeoecological events and changes. A critical study of dating methods rounds off the book.
