As an example, to have sandwich-peak Gb, 11 flint systems was explained [106, 107]

Flint procurement models on Payre mean differences in belongings have fun with using big date, possibly on account of variations in the size of field anywhere between equipment Grams and you will F. Unit Grams is getting filed a lot of time-label occupations whenever you are tool F shows short-identity business within the an inferior cave (predicated on meso- and you may mini-wear studies to your ungulate pearly whites) [104, 105]. All flint came from the brand new southern plateau over the Rhone River, after the a north-Southern axis. Flint was amassed primarily with the first formations or at secondary formations such as for instance fluvial deposits, discovered off 5 to help you 15 km around the site, just like the fragments regarding nodules otherwise highest flakes. Particular highest flakes and you will nodules originated 31 km or brief flakes out of 60 kilometer towards the south of your webpages (reflecting limited avoidance techniques). The fresh Rhone valley by itself try barely utilized for flint procurement. In contrast, in Device F all flint are accumulated off alluvial deposits (90%). The actual precise location of the outcrops was for this reason impractical to pick and only a max perimeter can be offered. Ten brands was in fact recognized, some of which also are based in the product G assemblage. Flint collecting try achieved significantly more west of the latest web site than just is the case to own unit Grams, but there clearly was once more certain event from the southern area.

New basalt from the one or two basal gadgets is actually amassed on root of the webpages, in the stays off terraces toward hill. Pri of one’s Payre River regarding volcanic massif of your Coiron. Basalt is actually delivered since the pebbles of several types or as highest flakes; all of the gravel were remaining entire. Despite the poorly maintained low surfaces of your pebbles, specific show percussion merstones. The fresh elongated and apartment gravel was indeed formed to your unifacial pebble-gadgets and you can kept numerous cortical flakes. Smashing scratching and you will flakes from rejuvenation vouch for its include in situ.

There are even a number of flint systems which sources has actually maybe not already been known, however these account fully for a highly small number of parts

Regional quartz arrived as the rare pebbles and you will first and foremost since flakes. The latest protection procedure are limited . The fresh new uncommon cores has actually a couple of secant or orthogonal counters. Just like the try the fact into the flint, flaking are mainly did from the a series of unipolar removals, hardly centripetal. Particular highest parts will be altered cores (crush scratches anastasiadate sign up for the cutting edges) or are highest products with the fragments from pebbles. The newest flakes try thick and regularly backed. Ranging from ten and you will 15% try retouched (that edge or convergent corners).

This new marly and you will siliceous limestones have been accumulated regarding the Payre otherwise Rhone Canals. Particular fragments of your cavern limestone was gathered and just retouched. Gravel was in fact busted or molded. Flakes are many, narrow, mainly cortical and small, and you can imported, as for quartz. Few are retouched. One or two limestone cores when you look at the level Fa can’t be refitted having flakes. Brand new flaking occurred on the brief flat pebbles and you may cores which have one or two secant counters.

Quartzite turned up due to the fact pebbles and you will first of all since of varying sizes flakes, gathered possibly along side Rhone River. The large flakes was cortical or partially cortical. Crushing scratching towards the sides help a great explore to own big points. One bit would be thought to be a core otherwise an effective re-used busted bifacial tool. Quick flakes you will definitely come from the fresh rejuvenation of the hefty-obligation units otherwise was indeed brought in having unfamiliar explanations, just as in the massive basalt products to your flakes.

The large flakes, flaked off high cobbles beyond your webpages, is unretouched otherwise retouched because higher unifacial or bifacial devices (peripheral, directed or transversal)

From the Bau de l’Aubesier, almost the entire assemblage is during flint, nevertheless has been you can to acknowledge many different types of flint and you may tune her or him back once again to resource areas on the part, along with take a look at different features each and every origin city that would dictate hominins’ choice of even if (or just how much) to use it [108, 109, 110, 111, 112, 113, 114]. In most profile, a sizeable proportion of the lithic assemblage has been patinated so you can such as for example a level the pieces is only able to end up being identified as getting flint, with no supply are going to be attributed. Taking this type of with the patinated pieces, although not, in the account J-J4 together, the sources of 43.2% of one’s pieces can be unfamiliar otherwise unidentifiable; when you look at the account K-K2 this type of be the cause of 51.7% out-of pieces.
