Flint procurement designs from the Payre indicate variations in residential property have fun with through go out, possibly due to differences in the duration of industry ranging from units G and you can F. Device G is having submitted long-identity jobs while you are equipment F reflects brief-identity job inside a smaller sized cavern (according to meso- and you may mini-wear knowledge towards the ungulate teeth) [104, 105]. All Flint originated this new southern area plateau along the Rhone River, adopting the a north-South axis. Flint is gathered mainly into no. 1 formations otherwise in the secondary structures such as fluvial places, found off 5 to fifteen km within the web site, because the fragments away from nodules or large Flakes. Particular high flakes and you can nodules originated from 31 kilometres otherwise short flakes away from sixty km south of site (reflecting limited prevention processes). The latest Rhone area itself was hardly used in flint procurement. However, inside Product F all the flint is obtained away from alluvial places (90%). The exact precise location of the outcrops are thus impractical to pick and simply a max edge is generally offered. Ten sizes had been recognized, some of which are based in the equipment G assemblage. Flint event is actually carried out a great deal more west of the latest site than simply is the situation to own device Grams, however, there can be once more certain collecting regarding southern area.

The fresh new basalt on the a couple basal products is actually accumulated on root of the site, on the stays out of terraces with the hill. Pri of your Payre Lake on eruptive massif of your Coiron. Basalt try introduced due to the fact pebbles of several systems or once the highest flakes; all the pebbles had been left whole. Inspite of the defectively maintained low surfaces of the pebbles, certain reveal percussion merstones. Brand new elongated and you may apartment gravel have been formed to the unifacial pebble-units and you can leftover multiple cortical flakes. Smashing scratching and flakes regarding restoration vouch for the include in situ.

There are also a few flint sizes which sources enjoys maybe not already been understood, but these make up a very few pieces

Regional quartz turned up given that rare pebbles and first of all once the flakes. The newest avoidance techniques was partial . The brand new rare cores have two secant or orthogonal surfaces. As the is actually the case on the flint, peeling try generally performed by the a series of unipolar removals, scarcely centripetal. Particular high pieces could be altered cores (smash scratches into the reducing sides) otherwise was higher products to your fragments out of pebbles. New flakes is actually heavy and regularly supported. Between 10 and you can 15% is actually retouched (you to definitely boundary or convergent edges).

The brand new marly and siliceous limestones have been collected regarding Payre otherwise Rhone Canals. Some fragments of cave limestone was in fact obtained and simply retouched. Pebbles were busted otherwise shaped. Flakes are numerous, slim, mainly cortical and quick, and brought in, for quartz. Few are retouched. A few limestone cores into the level Fa cannot be refitted having flakes. The fresh new peeling took place for the small flat gravel and you may cores which have one or two secant surfaces.

Quartzite showed up as the gravel and you may to start with just like the of varying sizes flakes, gathered perhaps along side Rhone Lake. The massive flakes is actually cortical or partly cortical. Crushing scratches towards the edges support a beneficial fool around with getting heavy facts. Just one piece could well be thought to be a center or a re-put busted bifacial tool. Small flakes you’ll come from the restoration of your big-obligations tools otherwise was in fact imported getting unfamiliar reasons, as with the massive basalt tools into flakes.

The massive flakes, flaked off high cobbles outside of the site, is actually unretouched otherwise retouched because the large unifacial or bifacial tools (peripheral, pointed otherwise transversal)

On Bau de l’Aubesier, almost the complete assemblage is in flint, but it has been you can to acknowledge various sorts of flint and song them back to supply section on area, together with see multiple qualities each and every resource town who determine hominins’ assortment of no matter if (otherwise simply how much) to use it [108, 109, 110, 111, 112, 113, 114]. In every account, a significant ratio of one’s lithic assemblage could have been patinated to help you like an extent that parts can only just be recognized as becoming flint, and no origin are charged. Delivering these making use of the patinated pieces, but not, from inside the account J-J4 along with her, what causes 43.2% of the parts are either as yet not known or unidentifiable; in the membership K-K2 these types of make up 51.7% out of bits.
