Flint procurement activities at the Payre suggest differences in belongings use using date, possibly because of variations in the size of profession between units G and you can F. Tool G represents having recorded much time-identity employment whenever you are device F reflects small-title occupations from inside the a smaller sized cavern (considering meso- and you can micro-wear degree into the ungulate teeth) [104, 105]. All flint originated in the newest southern plateau over the Rhone Lake, adopting the a north-Southern area axis. Flint try built-up primarily with the primary structures otherwise within secondary formations such as for instance fluvial dumps, discover off 5 so you can 15 kilometres within the site, as fragments out of nodules or highest flakes. Some high flakes and you can nodules came from 31 km otherwise small flakes away from sixty km to the south of your web site (reflecting partial reduction process). The fresh Rhone area by itself are scarcely employed for flint procurement. On the other hand, within the Equipment F every flint are compiled out of alluvial deposits (90%). The actual location of the outcrops try thus impossible to pick and only a max perimeter is generally provided. 10 brands was understood, some of which are also based in the unit Grams assemblage. Flint get together was achieved a lot more west of the site than is the case to own equipment Grams, however, there’s again certain event on southern area.

The basalt on the several basal units was accumulated within base of the website, in the remains of terraces on mountain. Pri of the Payre River in the volcanic massif of your Coiron. Basalt is produced since pebbles of several models or given that higher flakes; all the pebbles was indeed remaining entire. Despite the defectively managed low counters of your own pebbles, specific reveal percussion merstones. The fresh new elongated and you will flat pebbles have been formed towards the unifacial pebble-devices and you can remaining numerous cortical flakes. Smashing scratches and you will flakes off restoration attest to the include in situ.

There are even several flint designs by which sources keeps maybe not been known, however these account for an extremely small number of pieces

Local quartz showed up just like the unusual gravel and you may first and foremost because flakes. The new cures procedure was partial . This new uncommon cores keeps two secant or orthogonal counters. As is the scenario on flint, flaking try primarily performed from the several unipolar removals, scarcely centripetal. Some highest parts will be changed cores (smash marks into reducing sides) or is high gadgets to the fragments out of gravel. The brand new flakes try thick and frequently recognized. Between ten and you will 15% is retouched (one edge otherwise convergent corners).

This new marly and you will siliceous limestones was collected from the Payre or Rhone Canals. Certain fragments of one’s cave limestone have been gathered and only retouched. Pebbles had been damaged or shaped. Flakes are many, thin, mostly cortical and small, and you will imported, as for quartz. Not everyone is retouched. One aisle profile or two limestone cores for the height Fa can’t be refitted that have flakes. The fresh cracking took place into quick apartment gravel and you can cores having several secant counters.

Quartzite showed up as gravel and you may first off while the large and small flakes, built-up perhaps along the Rhone Lake. The massive flakes are cortical otherwise partly cortical. Smashing scratches into corners assistance an excellent use to possess heavier items. Singular part would be regarded as a core or an effective re-made use of damaged bifacial tool. Small flakes you can expect to come from the fresh new restoration of your heavy-duty systems or were brought in getting not familiar grounds, just as in the large basalt gadgets to your flakes.

The enormous flakes, flaked from higher cobbles beyond your web site, is unretouched otherwise retouched since the higher unifacial or bifacial gadgets (peripheral, pointed or transversal)

At the Bau de- l’Aubesier, nearly the entire assemblage is within flint, but it might have been it is possible to to identify various sorts of flint and you can tune them back again to supply portion about part, as well as look at many different qualities of each and every origin city who does determine hominins’ variety of regardless of if (otherwise how much cash) to use it [108, 109, 110, 111, 112, 113, 114]. In most account, a considerable proportion of the lithic assemblage might have been patinated to help you for example an extent your pieces can simply be identified as becoming flint, and no origin will be attributed. Providing these types of with the patinated parts, but not, into the membership J-J4 with her, the sources of 43.2% of your own parts can be unfamiliar otherwise unidentifiable; for the account K-K2 this type of account for 51.7% of parts.
