For You Lot Data - Experimental Function Reproduces The Knapping Procedure At Olduvai

Alfonso Benito Calvo, a geologist at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has participated inwards a newspaper published latterly inwards the magazine Archaeological together with Anthropological Sciences, which reproduced the knapping procedure observed at Olduvai (Tanzania), using i of the nearly abundant raw materials at those sites, quartzite rocks.

This was experimental tumble out which members from the CENIEH, University College London, Max Planck Institute together with from the Universidad Autónoma de Barcelona accept collaborated, based on studying the spatial patterns of the refits, that is to say, the assembly or matching of the lithic textile to reconstruct the master copy geometry prior to knapping.

First, the quartzite rocks were knapped, together with and then the position together with orientation of each resulting fragment were plotted exhaustively, yielding detailed maps showing the distribution of the materials.

"Starting from these maps, nosotros accept carried out a spatial analysis of the layout of the fragments together with their refits, using GIS applications, designed for specialist analysis of spatial databases," explains Benito.

The results obtained accept shown rattling dissimilar spatial patterns feature of each knapping technique: bipolar or freehand. Comparison of these theoretical experimental patterns amongst the distribution institute inwards the sites volition permit the total of post-depositional disturbance suffered past times the sites to hold out quantified, together with hence farther investigation of the processes which accept affected them.
