Flint procurement patterns during the Payre mean variations in belongings fool around with owing to time, maybe on account of variations in the size of career between tools Grams and you may F. Product Grams is known as to have recorded a lot of time-title employment if you find yourself unit F reflects brief-label work inside the a smaller cave (according to meso- and micro-wear knowledge on the ungulate white teeth) [104, 105]. Every flint originated the fresh new south plateau along the Rhone Lake, following a northern-Southern area axis. Flint try obtained mostly on the first formations otherwise from the second structures such as for instance fluvial dumps, discover off 5 so you’re able to fifteen kilometer inside the site, as the fragments off nodules or higher flakes. Specific large flakes and you can nodules originated 30 kilometres otherwise small flakes from sixty kilometer to the south of website (showing limited prevention process). Brand new Rhone area in itself try barely used in flint procurement. Alternatively, for the Equipment F all flint is actually gathered away from alluvial dumps (90%). The specific location of the outcrops is thus impossible to choose and just a max perimeter is generally offered. Ten sizes was basically known, many of which are based in the device Grams assemblage. Flint get together is accomplished much more west of the fresh new web site than is the situation for unit Grams, however, you will find once again specific collecting in the southern.
New basalt throughout the a few basal systems try built-up at the root of the webpages, from the stays regarding terraces into the hill. Pri of the Payre River regarding the eruptive massif of your Coiron. Basalt is actually lead just like the gravel of various products otherwise given that highest flakes; all of the pebbles have been remaining entire. Despite the badly maintained shallow surfaces of your own pebbles, certain inform you percussion merstones. New elongated and you will flat pebbles was formed towards the unifacial pebble-tools and you can remaining several cortical flakes. Smashing marks and flakes from restoration attest to the include in situ.
Regional quartz showed up because the uncommon pebbles and you will most importantly just like the flakes. The newest cures processes is limited . The fresh new uncommon cores has actually a couple of secant or orthogonal counters. Once the was the scenario towards the flint, cracking was mainly did from the a few unipolar removals, scarcely centripetal. Specific large pieces could be changed cores (crush scratches to the reducing corners) otherwise try higher tools towards the fragments of gravel. New flakes try heavy and often backed. Anywhere between ten and you will 15% is actually retouched (you to definitely boundary or convergent corners).
This new marly and you can siliceous limestones have been gathered from the Payre otherwise Rhone Rivers. Some fragments of your own cavern limestone have been obtained and simply retouched. Pebbles was broken or designed. Flakes are many, thin, mostly cortical and you can brief, and brought in, for quartz. Few are retouched. A couple limestone cores in the peak Fa can not be refitted which have flakes. The latest flaking occurred on the small apartment gravel and you can cores which have one or two secant surfaces.
Quartzite turned up because the pebbles and you will first and foremost as the large and small flakes, accumulated possibly across the Rhone River. The enormous flakes try cortical otherwise partly cortical. Crushing marks to the sides service an excellent have fun with for heavier situations. Only 1 piece was regarded as a core or a great re-made use of busted bifacial product. Small flakes could are from the latest rejuvenation of heavy-responsibility tools or had been brought in for unknown reasons, just as in the enormous basalt equipment toward flakes.
In the Bau de- l’Aubesier, almost the whole assemblage is actually flint, nonetheless it has been you can to recognize many different types of flint and you can track her or him back again to provider areas from the region, along with examine several features of any provider area who would dictate hominins’ choice of even if (or simply how much) to use it [108, 109, 110, 111, 112, 113, 114]. Throughout levels, a significant ratio of your own lithic assemblage might have been patinated so you can like a degree that bits can only just getting recognized as becoming flint, with no provider would be attributed. Getting this type of making use of patinated pieces, but not, inside levels J-J4 with her, what causes 43.2% of one’s pieces are either unidentified otherwise unidentifiable; during the levels K-K2 321Chat prices these types of take into account 51.7% regarding bits.
