Flint procurement patterns during the Payre imply variations in residential property play with as a consequence of day, perhaps on account of differences in the duration of community anywhere between devices G and you will F. Unit Grams is to possess registered a lot of time-name occupations while you are product F reflects short-identity business inside a smaller cave (considering meso- and you can mini-don knowledge with the ungulate teeth) [104, 105]. Every flint came from the latest southern plateau across the Rhone River, after the a northern-South axis. Flint was gathered mainly to the no. 1 formations otherwise from the secondary formations for aisle example fluvial places, found out of 5 to fifteen kilometer within website, once the fragments from nodules or high flakes. Certain high flakes and you may nodules originated from 29 kilometres otherwise small flakes off sixty km towards the south of the web site (reflecting partial avoidance techniques). The latest Rhone valley in itself is actually barely utilized for flint procurement. On the other hand, inside Unit F most of the flint are compiled away from alluvial deposits (90%). The particular location of the outcrops is ergo impossible to identify and only a max edge is generally offered. 10 models was understood, many of which are also found in the tool G assemblage. Flint get together is accomplished a whole lot more to the west of the web site than just is the case getting equipment G, however, there is certainly again particular meeting in the southern area.
The fresh basalt regarding the several basal gadgets are amassed within foot of the webpages, regarding stays away from terraces for the hill. Pri of your Payre River regarding the volcanic massif of one’s Coiron. Basalt is actually produced since pebbles of several designs or since high flakes; most of the pebbles was left whole. Regardless of the poorly kept low surfaces of the gravel, some let you know percussion merstones. The latest elongated and you may apartment pebbles had been designed on the unifacial pebble-devices and you may left numerous cortical flakes. Smashing scratching and flakes away from restoration attest to their include in situ.
There are also a few flint designs in which supply provides maybe not been recognized, however these account fully for an extremely few pieces
Regional quartz showed up due to the fact uncommon pebbles and you can above all once the flakes. This new protection process is actually partial . The new rare cores have two secant otherwise orthogonal surfaces. Since is actually the fact towards the flint, peeling was primarily did by several unipolar removals, scarcely centripetal. Specific higher bits was altered cores (break marks towards the reducing edges) otherwise are high tools on fragments off gravel. This new flakes was thick and frequently supported. Ranging from ten and you can fifteen% is retouched (you to boundary otherwise convergent edges).
The marly and you can siliceous limestones was indeed built-up on Payre or Rhone Canals. Some fragments of the cavern limestone was amassed and just retouched. Gravel was basically broken or formed. Flakes are many, thin, mainly cortical and small, and you may imported, in terms of quartz. Not everyone is retouched. Two limestone cores inside top Fa can not be refitted which have flakes. The new cracking taken place into the brief flat pebbles and you may cores that have one or two secant counters.
Quartzite turned up as gravel and you can most importantly since of varying sizes flakes, collected possibly across the Rhone River. The massive flakes was cortical or partially cortical. Crushing marks on edges assistance an effective use to have hefty circumstances. Singular part would-be thought to be a core otherwise a great re-used busted bifacial equipment. Small flakes could come from the new vitality of your own hefty-obligations tools otherwise had been brought in to have not familiar grounds, like with the massive basalt equipment for the flakes.
The massive flakes, flaked of large cobbles outside of the site, is actually unretouched or retouched given that high unifacial or bifacial gadgets (peripheral, pointed otherwise transversal)
From the Bau de- l’Aubesier, almost the whole assemblage is in flint, nevertheless has been possible to recognize various sorts of flint and you can song them back again to supply parts from the region, as well as evaluate some properties each and every supply urban area who does influence hominins’ choice of regardless of if (otherwise exactly how much) for action [108, 109, 110, 111, 112, 113, 114]. In most profile, a significant proportion of one’s lithic assemblage could have been patinated so you can eg a degree that the pieces could only become defined as becoming flint, and no source is charged. Getting these types of because of the patinated pieces, yet not, inside the accounts J-J4 along with her, the sources of 43.2% of pieces are either unfamiliar or unidentifiable; when you look at the membership K-K2 these take into account 51.7% from parts.
