Flint procurement designs from the Payre imply differences in home fool around with as a consequence of go out, perhaps on account of variations in the size of community ranging from gadgets Grams and you can F. Product Grams is known as having submitted a lot of time-title occupations while you are tool F reflects small-title occupations inside the a smaller cavern (centered on meso- and you may micro-wear degree towards ungulate white teeth) [104, 105]. Every flint originated this new southern plateau along side Rhone Lake, after the a north-South axis. Flint are collected mainly with the number 1 structures otherwise at supplementary structures eg fluvial dumps, discovered regarding 5 to help you fifteen kilometer in the site, because the fragments of nodules or higher flakes. Particular highest flakes and nodules originated from 30 kilometer otherwise small flakes from 60 kilometer to the south of your own site (highlighting partial protection processes). The fresh new Rhone valley alone are scarcely employed for flint procurement. On the other hand, within the Product F the flint is actually gathered out-of alluvial deposits (90%). The precise location of the outcrops are for this reason impossible to choose and just a maximum edge can be considering. 10 models was basically identified, many of which also are based in the equipment G assemblage. Flint gathering was carried out alot more west of this new web site than is the situation to possess unit Grams, however, there clearly was once more certain collecting throughout the southern area.

The newest basalt regarding two basal devices are built-up on base of the web site, regarding stays away from terraces to your mountain. Pri of your own Payre Lake regarding the eruptive massif of Coiron. Basalt try put because the pebbles beautifulpeople of several items or just like the high flakes; all the gravel have been kept whole. In spite of the poorly preserved low surfaces of your gravel, particular inform you percussion merstones. Brand new elongated and you will flat pebbles was designed toward unifacial pebble-systems and you will left numerous cortical flakes. Crushing scratches and you can flakes out of restoration vouch for its use in situ.

There are also several flint designs in which present provides perhaps not started known, nevertheless these be the cause of an incredibly few bits

Regional quartz showed up once the uncommon gravel and you can first off because flakes. Brand new reduction procedure is limited . New rare cores enjoys two secant otherwise orthogonal surfaces. Once the try the fact into the flint, peeling try generally performed by the a few unipolar removals, barely centripetal. Some higher parts might possibly be modified cores (break scratches towards the cutting corners) or is actually high systems into fragments of pebbles. This new flakes are dense and often recognized. Anywhere between 10 and you may fifteen% are retouched (one to border otherwise convergent corners).

New marly and siliceous limestones was basically obtained on the Payre or Rhone Streams. Certain fragments of your cave limestone were gathered and just retouched. Gravel were busted or designed. Flakes are numerous, thin, largely cortical and you will short, and you may imported, as for quartz. Few are retouched. One or two limestone cores into the height Fa can not be refitted having flakes. The fresh new flaking occurred with the brief apartment gravel and you can cores with one or two secant surfaces.

Quartzite showed up because pebbles and you may first and foremost because of varying sizes flakes, obtained perhaps across the Rhone River. The enormous flakes try cortical otherwise partly cortical. Crushing marks into sides support an effective use to possess heavier factors. Only 1 bit would-be regarded as a core otherwise an effective re-made use of busted bifacial device. Short flakes you can expect to come from this new rejuvenation of one’s hefty-obligations equipment or were brought in getting unknown reasons, just as in the large basalt units into the flakes.

The huge flakes, flaked from high cobbles beyond your site, try unretouched otherwise retouched due to the fact highest unifacial otherwise bifacial products (peripheral, directed or transversal)

Within Bau de l’Aubesier, almost the complete assemblage is in flint, it might have been you can to recognize many different types of flint and track him or her back once again to resource components regarding the part, in addition to glance at many different attributes each and every source city who dictate hominins’ collection of even in the event (otherwise just how much) for action [108, 109, 110, 111, 112, 113, 114]. In every levels, a sizeable ratio of your own lithic assemblage might have been patinated in order to like an extent the parts are only able to be defined as being flint, no supply will be attributed. Bringing such making use of patinated bits, although not, into the profile J-J4 together, what causes 43.2% of your own bits are generally not known otherwise unidentifiable; into the accounts K-K2 such account fully for 51.7% from parts.
