Summary (English)
The stratigraphy documented on the site of Fosso delle Caldanelle from 2007-2009 was composed as follows, from bottom to top:
5- chloritic-sericitic schists eroded in a roof shape
4- alluvial deposit of cobbles
2-3 upper paleo-surface with reddish horizon (2) and a lower surface (3), that was sandier and yellow. Three levels were identified within layer 3, from bottom to top: c- sandy yellow level with inclusions of small limestone cobbles and scist fragments; b- sandy yellow level with reddish speckling; a- sandy yellow level.
6- sandy alluvial deposit with small cobbles
7- fairly thick (40 cm) deposit of hillside detritus constituted by sandy reddish sediment mixed with scists.
1- thin layer of dark brown humus (5 cm deep)The material recovered, all related to stone working, was present in levels 3 and 2, with a certain concentration at the roof of level 3a. Levels 3b and 3c were, on the contrary, almost sterile and produced only occasional fragments of flint and jasper.
Production was represented by jasper artefacts that were not retouched, thus supporting the suggestion that the site was a workshop. The elements recovered seemed to confirm the presence of a chain of operation whose primary objective was the production of blades and bladelets. Amongst the rare flint artefacts there was a retouched blade. Evidence seemed to show the heating of the flint in order to facilitate its flaking.
