Unit Grams is to possess registered a lot of time-name occupations while you are product F reflects short-identity business inside a smaller cave (considering meso- and you can mini-don knowledge with the ungulate teeth) [104, 105]. Every flint came from the latest southern plateau across the Rhone River, after the a northern-South axis. Flint was gathered mainly to the no. 1 formations otherwise from the secondary formations for aisle example fluvial places, found out of 5 to fifteen kilometer within website, once the fragments from nodules or high flakes. Certain high flakes and you may nodules originated from 29 kilometres otherwise small flakes off sixty km towards the south of the web site (reflecting partial avoidance techniques). The latest Rhone valley in itself is actually barely utilized for flint procurement. On the other hand, inside Unit F most of the flint are compiled away from alluvial deposits (90%). The particular location of the outcrops is ergo impossible to identify and only a max edge is generally offered. 10 models was understood, many of which are also found in the tool G assemblage. Flint get together is accomplished a whole lot more to the west of the web site than just is the case getting equipment G, however, there is certainly again particular meeting in the southern area.

The fresh basalt regarding the several basal gadgets are amassed within foot of the webpages, regarding stays away from terraces for the hill.

Regardless of the poorly kept low surfaces of the gravel, some let you know percussion merstones.

In most profile, a significant proportion of one’s lithic assemblage could have been patinated so you can eg a degree that the pieces could only become defined as becoming flint, and no source is charged. Getting these types of because of the patinated pieces, yet not, inside the accounts J-J4 along with her, the sources of 43.2% of pieces are either unfamiliar or unidentifiable; when you look at the membership K-K2 these take into account 51.7% from parts.
