Experimental works reproduce the carving process of the human groups of the Olduvai site
Alfonso Benito Calvo, geologist at the National Research Center on Human Evolution (CENIEH) (Spain), has participated in an article recently published in the Archaeological and Anthropological Sciences journal, on the reproduction of the carving process observed in Olduvai (Tanzania), using one of the most abundant raw materials in these deposits, the quartzite rocks.
This is an experimental work, in which members of CENIEH, University College London, the Max Planck Institute and the Autonomous University of Barcelona have collaborated, which has been based on the study of the spatial patterns of the remounting, this is, of the assembly or fit of the lithic material for the reconstruction of its original geometry before being carved.
First, the quartzite rocks were carved, after which an exhaustive cartography was made of the position and orientation of each remaining size, producing detailed maps with the distribution of materials.
"Based on these maps, we have carried out a spatial analysis of the distribution of the size remains and their overruns, using GIS software, specialized in the analysis of spatial databases," explains Alfonso Benito.

The results obtained have shown very different spatial patterns and characteristics differentiated according to the type of size: bipolar or by hand. The comparison of these theoretical experimental patterns with the distribution found in the deposits will allow to quantify the degree of post-depositional transformation suffered by the deposits and to investigate the processes that have affected them.
