As an instance, getting sub-height Gb, 11 flint brands was indeed discussed [106, 107]
Flint procurement designs at Payre indicate variations in house have fun with as a consequence of go out, perhaps because of variations in the size of profession ranging from gadgets Grams and you will F. Device Grams represents to possess registered a lot of time-identity job while product F shows small-identity employment in a smaller cave (predicated on meso- and you may micro-wear education on the ungulate pearly whites) [104, 105]. All the flint came from the brand new southern plateau across the Rhone Lake, adopting the a northern-Southern area axis. Flint was compiled mostly towards the number one structures otherwise from the secondary structures like fluvial deposits, receive from 5 to help you 15 km around the webpages, once the fragments off nodules or highest flakes. Particular highest flakes and you will nodules originated from 31 km otherwise quick flakes regarding 60 km towards the south of the site (highlighting partial avoidance processes). The Rhone area in itself are hardly used in flint procurement. Conversely, for the Equipment F all of the flint is actually collected away from alluvial dumps (90%). The precise location of the outcrops is hence impractical to choose and only a maximum fringe may be offered. 10 versions was known, some of which are found in the tool G assemblage. Flint event are carried out a whole lot more to the west of new web site than just is the situation having equipment Grams, but there clearly was once again specific event in the southern.
The new basalt about one or two basal equipment are collected during the base of the website, from the stays from terraces towards the slope. Pri of one’s Payre River regarding eruptive massif of the Coiron. Basalt try brought given that gravel of numerous products otherwise once the highest flakes; all gravel have been left entire. Inspite of the improperly maintained shallow counters of one’s gravel, certain inform you percussion merstones. Brand new elongated and apartment gravel have been shaped into the unifacial pebble-gadgets and kept several cortical flakes. Smashing scratching and you will flakes out of restoration attest to the include in situ.
There are also a number of flint designs for which source enjoys not been known, but these take into account an extremely few pieces
Regional quartz arrived just like the unusual gravel and you will to start with since flakes. Brand new cures techniques try partial . The newest rare cores has one or two secant or orthogonal surfaces. Since the are happening to your flint, flaking is actually generally did by the a series of unipolar removals, scarcely centripetal. Specific higher pieces might possibly be modified cores (crush scratches into cutting corners) or is large gadgets for the fragments regarding pebbles. Brand new flakes are thick and sometimes recognized. Anywhere between 10 and you may fifteen% are retouched (one edge otherwise convergent corners).
The latest marly and you will siliceous limestones was gathered regarding the Payre otherwise Rhone Canals. Particular fragments of cavern limestone had been accumulated and only retouched. Gravel was basically broken otherwise shaped. Flakes are numerous, thin, mostly cortical and you will small, and you will brought in, as for quartz. Few are retouched. A couple of limestone cores during the level Fa can not be refitted which have flakes. The brand new flaking taken place into brief flat gravel and cores with a couple of secant surfaces.
Quartzite turned up while the gravel and to start with because the large and small flakes, built-up perhaps along side Rhone River. The enormous flakes is cortical or partially cortical. Smashing scratches towards the corners service a good have fun with having heavy items. Singular section would-be regarded as a core otherwise an effective re-made use of busted bifacial tool. Short flakes could are from the newest restoration of your heavier-obligations products otherwise were brought in for unfamiliar causes, as with the chappy log in enormous basalt equipment on flakes.
The massive flakes, flaked out of higher cobbles beyond your website, are unretouched or retouched since the large unifacial or bifacial systems (peripheral, directed or transversal)
During the Bau de l’Aubesier, nearly the complete assemblage is during flint, nevertheless has been you’ll to identify many different types of flint and you will song him or her back to resource elements about area, and additionally have a look at several properties of each resource city that would determine hominins’ choice of regardless of if (or simply how much) for action [108, 109, 110, 111, 112, 113, 114]. In all account, a significant ratio of one’s lithic assemblage might have been patinated so you’re able to such a level that the pieces can simply feel recognized as becoming flint, without origin can be attributed. Taking these with all the patinated bits, however, inside accounts J-J4 along with her, the sources of 43.2% of your pieces can be unknown or unidentifiable; inside the account K-K2 this type of make up 51.7% from pieces.
