Abstract

Colluvial deposits consisting of silts and loams were detected in several climatologically different areas of NE Tibet. Layering, distinct organic content and low content of coarse matter as well as location in the relief revealed an origin from low-energy slope erosion (hillwash). Natural or anthropogenic factors could have been the triggers of the erosional processes derived. Determinations of charcoal and fossil wood revealed the Holocene occurrence of tree species (spruce, juniper) for areas which nowadays have no trees. Thus large areas of NE Tibet which are at present steppes and alpine pastures were forested in the past
