Flint procurement habits from the Payre imply variations in residential property explore owing to big date, possibly due to variations in the duration of community anywhere between systems G and you can F. Unit Grams represents for registered much time-title business when you’re tool F shows quick-term jobs in a smaller sized cave (according to meso- and you may small-wear training to your ungulate teeth) [104, 105]. All the flint originated from the newest southern plateau along the Rhone River, following the a north-Southern axis. Flint is gathered mainly into the primary structures or on additional structures such fluvial places, discover away from 5 so you’re able to 15 km within the webpages, as fragments out-of nodules or higher flakes. Specific high flakes and you can nodules originated from 31 kilometer otherwise brief flakes away from 60 kilometres to the south of one’s website (highlighting partial avoidance procedure). New Rhone valley alone is barely utilized for flint procurement. Conversely, during the Tool F all the flint was accumulated out-of alluvial deposits (90%). The exact precise location of the outcrops is actually therefore impossible to pick and only a max fringe could be considering. Ten products had been identified, many of which are also based in the tool G assemblage. Flint gathering was carried out a great deal more to the west of the fresh new web site than simply is the situation having equipment G, however, there’s again particular meeting in the south.

The basalt on the two basal tools try gathered on base of the webpages, throughout the stays of terraces to your mountain. Pri of the Payre Lake about volcanic massif of Coiron. Basalt try put as the gravel of several versions otherwise just like the highest flakes; all of the gravel was left whole. Inspite of the improperly maintained low counters of one’s pebbles, some let you know percussion merstones. This new elongated and you may apartment pebbles had been molded toward unifacial pebble-gadgets and you will left multiple cortical flakes. Smashing scratches and flakes away from vitality attest to their use in situ.

There are even a few flint models whereby sources features maybe not been recognized, however these account fully for an incredibly few parts

Local quartz turned up once the unusual pebbles and above all because the flakes. This new reduction procedure was limited . The fresh new unusual cores keeps two secant or orthogonal surfaces. As are the way it is towards flint, flaking was generally did by the some unipolar removals, rarely centripetal. Particular high pieces would-be altered cores (crush scratching towards the cutting sides) otherwise was higher gadgets for the fragments out of gravel. The newest flakes is actually heavy and sometimes backed. Anywhere between ten and you can 15% was retouched (one line or convergent sides).

The fresh new marly and you may siliceous limestones was in fact built-up in the Payre or Rhone Canals. Certain fragments of one’s cave limestone were collected and only retouched. Gravel was in fact broken otherwise shaped. Flakes are numerous, narrow, mainly cortical and small, and you may brought in, in terms of quartz. Not everyone is retouched. Several limestone cores into the top Fa cannot be refitted that have flakes. Brand new cracking took place on the quick apartment gravel and you may cores that have a couple secant surfaces.

Quartzite showed up because the gravel and you will first of all while the large and small flakes, collected possibly along side Rhone River. The massive flakes try cortical otherwise partially cortical. Crushing scratching on sides help an effective fool around with to have heavy things. Only one bit is considered as a core or a beneficial re-put damaged bifacial product. Brief flakes you may come from the new restoration of one’s big-duty systems otherwise were brought in to own unfamiliar causes, as with the enormous basalt systems into flakes.

The huge flakes, flaked off high cobbles away from site, is actually unretouched otherwise retouched as the highest unifacial or bifacial units (peripheral, pointed otherwise transversal)

At Bau de l’Aubesier, almost the complete assemblage is actually flint, it could have been you can to identify many different types of flint and tune them back into source portion regarding area, in addition to check multiple qualities of each and every supply urban area who does influence hominins’ assortment of whether or not (otherwise just how much) for action [108, 109, 110, 111, 112, 113, 114]. In most accounts, a sizeable proportion of one’s lithic assemblage has been patinated to help you eg a level that parts is only able to end up being identified as becoming flint, and no origin would be blamed. Getting these utilizing the patinated pieces, not, for the membership J-J4 together, what causes 43.2% of your bits can be as yet not known otherwise unidentifiable; inside account K-K2 these account fully for 51.7% away from parts.
