Flint procurement models in the Payre mean differences in belongings have fun with due to date, maybe because of variations in the length of community anywhere between tools Grams and F. Equipment Grams is known as to own registered much time-name employment while tool F reflects small-identity business in the a smaller sized cavern (predicated on meso- and mini-don education for the ungulate teeth) [104, 105]. The flint came from brand new southern area plateau over the Rhone Lake, following the a north-Southern axis. Flint are amassed mostly to the no. 1 structures otherwise on additional structures such as for example fluvial deposits, found of 5 to fifteen km around the web site, as the fragments off nodules or high flakes. Specific higher flakes and you can nodules originated in 30 km otherwise small flakes away from 60 kilometer towards the south of web site (showing limited prevention processes). Brand new Rhone area by itself is actually hardly employed for flint procurement. In contrast, into the Equipment F all of the flint was amassed regarding alluvial deposits (90%). The specific located area of the outcrops was for this reason impractical to select and simply an optimum fringe are provided. Ten designs was basically recognized, many of which are also based in the equipment G assemblage. Flint get together are carried out a lot more west of the webpages than simply is the situation for product Grams, but there was once again certain collecting in the southern area.
The basalt on the two basal products try built-up within foot of the site, regarding the remains out-of terraces to the slope. Pri of your own Payre River throughout the eruptive massif of your own Coiron. Basalt is actually put since the pebbles of various systems otherwise just like the highest flakes; every pebbles were kept whole. In spite of the badly maintained superficial counters of one’s pebbles, particular let you know percussion merstones. Brand new elongated and you can flat pebbles was in fact shaped towards the unifacial pebble-gadgets and you may leftover numerous cortical flakes. Smashing marks and you may flakes regarding restoration vouch for their include in situ.
There are even a few flint items where supply possess not been identified, however these take into account a very small number of parts
Local quartz turned up while the unusual pebbles and you can first off given that flakes. The newest protection techniques was partial . The new unusual cores features several secant or orthogonal surfaces. Because is actually the outcome for the flint, cracking was generally performed of the some unipolar removals, hardly centripetal. Certain high pieces would-be altered cores (smash scratching into reducing edges) or is actually higher systems towards fragments out of pebbles. The brand new flakes is actually thick and often supported. Between 10 and you may 15% is actually retouched (one to line otherwise convergent edges).
The new marly and you will siliceous limestones were gathered regarding Payre or Rhone Rivers. Specific fragments of your own cavern limestone were accumulated and only retouched. Pebbles had been broken otherwise molded. Flakes are numerous, thin, mostly cortical and you will brief, chatavenue desktop and you will brought in, for quartz. Few are retouched. A few limestone cores inside the level Fa can’t be refitted having flakes. The brand new flaking happened on short apartment gravel and cores that have a few secant surfaces.
Quartzite turned up because pebbles and you can first of all because of varying sizes flakes, gathered maybe along the Rhone River. The massive flakes try cortical or partly cortical. Crushing marks towards sides help good explore to possess heavy items. One part would-be considered as a center otherwise a great re-used damaged bifacial product. Small flakes could are from the fresh new rejuvenation of one’s hefty-responsibility units otherwise was brought in having unfamiliar factors, just as in the large basalt systems on flakes.
The huge flakes, flaked off highest cobbles outside the site, is actually unretouched or retouched once the high unifacial otherwise bifacial devices (peripheral, pointed otherwise transversal)
Within Bau de- l’Aubesier, almost the whole assemblage is during flint, but it has been you are able to to recognize various sorts of flint and you may song them back once again to origin elements about part, including glance at many qualities of each and every provider area who does dictate hominins’ assortment of although (otherwise just how much) to use it [108, 109, 110, 111, 112, 113, 114]. In every levels, a considerable proportion of one’s lithic assemblage might have been patinated to for example a degree that parts can only end up being defined as being flint, with no resource is going to be blamed. Delivering these aided by the patinated bits, but not, when you look at the levels J-J4 together, what causes 43.2% of parts can be unfamiliar or unidentifiable; in the membership K-K2 this type of account fully for 51.7% regarding pieces.
