Description :
By the example of Tigray/Ethiopia this contribution demonstrates the importance of the multi-proxy colluvial deposit, while emphasising it's suitability for geoarchaeological and palaeopedological research. The analysis of colluvial deposits, paleosols and phytoliths in Yeha illustrate existing links between ancient land-use being part of the Ethio-Sabaean culture and different stratigraphic units. While the study of colluvial deposits provide answers on cultural chronology and land-use-changes, the study of paleosols buried by or formed within these colluvial deposits makes it possible to demonstrate Holocene climate change along the intertropical convergence zone (ITCZ)
