Flint procurement activities during the Payre mean differences in land play with using day, maybe because of variations in along community ranging from systems Grams and F. Unit Grams is recognized as getting recorded a lot of time-title job when you are unit F reflects short-identity work inside the a smaller cavern (according to meso- and you may mini-don knowledge towards ungulate white teeth) [104, 105]. Every flint originated the fresh new southern plateau along side Rhone Lake, adopting the a northern-Southern axis. Flint is built-up mostly into the first structures otherwise in the second structures including fluvial dumps, found away from 5 to help you fifteen km around the web site, since fragments out-of nodules otherwise high flakes. Certain highest flakes and you can nodules came from 29 kilometer or brief flakes out-of 60 kilometres south of the website (showing partial reduction process). New Rhone area itself is barely utilized for flint procurement. In contrast, when you look at the Product F every flint was obtained regarding alluvial places (90%). The specific precise location of the outcrops try thus impossible to identify and only an optimum edge could be offered. 10 versions was basically known, some of which also are found in the product G assemblage. Flint meeting is accomplished so much more to the west of the newest website than simply is the case to possess tool G, however, there is certainly again specific gathering from the southern area.
This new basalt on the several basal systems are compiled from the foot of the webpages, throughout the stays off terraces towards slope. Pri of the Payre River regarding the eruptive massif of the Coiron. Basalt is brought while the gravel of numerous systems otherwise as the large flakes; all the pebbles have been remaining entire. Regardless of the badly managed shallow surfaces of the pebbles, certain show percussion merstones. New elongated and you may flat gravel had been designed towards the unifacial pebble-systems and kept several cortical flakes. Crushing marks and you will flakes of restoration vouch for the use in situ.
There are also several flint types where source keeps not already been known, nevertheless these be the cause of a highly small number of parts
Regional quartz turned up just like the unusual pebbles and you may most importantly since flakes. New protection techniques is limited . The latest unusual cores keeps one or two secant otherwise orthogonal surfaces. Just like the is actually the outcome into the flint, peeling was generally did from the several unipolar removals, barely centripetal. Particular highest pieces is modified cores (break marks into cutting edges) or is actually large gadgets toward fragments from pebbles. The fresh new flakes try heavy and frequently recognized. Between ten and you will fifteen% is retouched (you to definitely border or convergent edges).
This new marly and you may siliceous limestones was gathered regarding Payre otherwise Rhone Rivers. Some fragments of cave limestone had been gathered and only retouched. Gravel had been broken otherwise formed. Flakes are numerous, slim, mostly cortical and you can brief, and you will imported, for quartz. Not everyone is retouched. A couple limestone cores in the level Fa can’t be refitted with flakes. dating alua The brand new cracking took place with the short flat pebbles and you may cores which have a couple of secant surfaces.
Quartzite turned up because the gravel and you will to start with since the of varying sizes flakes, accumulated possibly across the Rhone River. The enormous flakes try cortical or partially cortical. Smashing scratches with the sides service a good explore to possess heavy factors. Singular bit might be regarded as a center or an excellent re-used busted bifacial device. Short flakes could are from the fresh vitality of the hefty-obligation systems otherwise was in fact imported for unfamiliar factors, just as in the enormous basalt products into flakes.
The massive flakes, flaked off large cobbles away from webpages, was unretouched otherwise retouched as highest unifacial or bifacial systems (peripheral, indicated otherwise transversal)
Within Bau de- l’Aubesier, almost the entire assemblage is actually flint, however it could have been you’ll be able to to identify many different types of flint and you will tune her or him back once again to source elements on the part, and consider many features of each origin town who does determine hominins’ assortment of in the event (otherwise exactly how much) to use it [108, 109, 110, 111, 112, 113, 114]. Throughout levels, a significant ratio of one’s lithic assemblage could have been patinated so you’re able to instance an extent the bits could only end up being defined as becoming flint, and no resource should be charged. Delivering such together with the patinated pieces, however, in accounts J-J4 together, what causes 43.2% of pieces are generally unidentified or unidentifiable; inside membership K-K2 these types of take into account 51.7% out of pieces.
