Flint procurement patterns in the Payre mean differences in house explore by way of time, perhaps due to differences in the duration of field ranging from tools G and F. Tool Grams is recognized as having recorded a lot of time-title job when you find yourself equipment F reflects short-name work when you look at the an inferior cavern (predicated on meso- and you may micro-don education towards the ungulate teeth) [104, 105]. All of the flint originated from the latest southern plateau along the Rhone Lake, after the a northern-South axis. Flint are obtained mainly to your no. 1 formations or from the secondary structures for example fluvial places, receive regarding 5 to help you 15 kilometer within webpages, since the fragments out-of nodules or higher flakes. Specific high flakes and you may nodules originated in 30 kilometer or quick flakes from 60 kilometres south of your own webpages (reflecting limited protection process). New Rhone valley in itself are barely utilized for flint procurement. In contrast, in the Device F all flint is accumulated out of alluvial places (90%). The location of the outcrops are hence impossible to pick and only an optimum perimeter could be given. Ten designs was identified, many of which are also found in the equipment G assemblage. Flint gathering was accomplished alot more to the west of new webpages than just is the case having unit Grams, but discover again specific gathering about southern.

Brand new basalt throughout the several basal units was compiled at the base of the site, regarding the remains out of terraces on hill. Pri of Payre River regarding eruptive massif of Coiron. Basalt is actually lead given that pebbles of several items otherwise while the higher flakes; all the pebbles was indeed left entire. In spite of the badly managed shallow counters of your pebbles, specific reveal percussion merstones. New elongated and apartment gravel was in fact designed for the unifacial pebble-systems and you may kept several cortical flakes. Smashing marks and you can flakes regarding restoration attest to their include in situ.

There are also several flint systems by which offer enjoys not started recognized, but these be the cause of an extremely few pieces

Regional quartz arrived while the unusual pebbles and first of all while the flakes. New protection process was limited . The new rare cores enjoys one or two secant or orthogonal surfaces. Just like the is the outcome toward flint, peeling is mainly performed by the a few unipolar removals, hardly centripetal. Certain high parts would-be modified cores (smash scratching towards reducing edges) otherwise is actually higher products on the fragments off gravel. The new flakes are thicker and sometimes backed. Anywhere between 10 and you will 15% is retouched (that line otherwise convergent corners).

The newest marly and you may siliceous limestones was basically compiled on the Payre or Rhone Canals. Particular fragments of your own cavern limestone was accumulated and only retouched. Gravel was in fact broken or shaped. Flakes are numerous, slim, mostly cortical and you will small, and brought in, as for quartz. Few are retouched. A few limestone cores inside the height Fa cannot be refitted with flakes. The peeling took place toward quick apartment pebbles and you will cores with one or two secant surfaces.

Quartzite arrived as the pebbles and first off as large and small flakes, compiled perhaps along the Rhone River. The large flakes are cortical otherwise partly cortical. Crushing scratches for the edges support good have fun with to own big facts. Only one piece could be thought to be a key or a great re-put busted bifacial device. Small flakes you may are from the brand new vitality of your big-obligations equipment otherwise had been brought in to have not familiar grounds, like with the large basalt devices towards flakes.

The large flakes, flaked of higher cobbles outside of the web site, are unretouched otherwise retouched due to the fact highest unifacial otherwise bifacial systems (peripheral, pointed or ardent transversal)

In the Bau de l’Aubesier, nearly the complete assemblage is actually flint, but it has been you can to recognize many different types of flint and you can track her or him back into provider elements in the area, including consider a number of functions of each origin area who determine hominins’ selection of regardless if (otherwise how much) for action [108, 109, 110, 111, 112, 113, 114]. In every membership, a significant proportion of lithic assemblage has been patinated to including an extent the bits can only be identified as being flint, with no provider is charged. Bringing these together with the patinated bits, not, within the profile J-J4 with her, the causes of 43.2% of the pieces are generally unfamiliar or unidentifiable; when you look at the account K-K2 this type of make up 51.7% away from parts.
