Flint procurement habits at Payre imply differences in land use by way of date, possibly because of differences in the size of occupation anywhere between products Grams and you may F. Device Grams is regarded as for registered long-label occupations if you’re tool F shows quick-name employment when you look at the an inferior cave (according to meso- and you can micro-don studies to your ungulate teeth) [104 is blackplanet free, 105]. The flint originated in the latest southern area plateau across the Rhone Lake, after the a north-Southern area axis. Flint are accumulated mostly to your primary formations otherwise in the second structures like fluvial dumps, discover from 5 to help you 15 kilometres within the site, as the fragments of nodules otherwise higher flakes. Particular highest flakes and nodules originated 30 kilometres or short flakes out of 60 kilometres south of web site (reflecting limited prevention procedure). The Rhone area itself was barely used for flint procurement. In contrast, when you look at the Unit F all flint are gathered of alluvial places (90%). The exact precise location of the outcrops is actually thus impractical to choose and simply a max fringe are provided. Ten products was basically identified, some of which are also found in the product Grams assemblage. Flint get together is accomplished even more west of new web site than just is the case getting equipment Grams, but you will find once again certain event throughout the southern area.
The basalt regarding two basal products is actually obtained in the foot of the webpages, from the remains out-of terraces towards slope. Pri of your own Payre Lake throughout the eruptive massif of your Coiron. Basalt is put as the pebbles of several types or due to the fact large flakes; all the pebbles was basically kept entire. Regardless of the poorly managed shallow surfaces of your gravel, certain let you know percussion merstones. The fresh elongated and you can flat gravel was indeed molded to the unifacial pebble-gadgets and leftover numerous cortical flakes. Smashing scratches and flakes out of vitality vouch for the use in situ.
There are also a number of flint systems wherein supplies provides not already been recognized, however these account fully for an extremely small number of parts
Local quartz turned up since rare pebbles and you may most importantly since flakes. The fresh new prevention process is limited . The fresh uncommon cores provides a few secant otherwise orthogonal counters. Just like the is actually the scenario towards flint, peeling try generally performed by the a few unipolar removals, hardly centripetal. Some highest pieces would-be altered cores (smash scratching into reducing corners) otherwise is actually high units into the fragments regarding pebbles. New flakes was thick and frequently supported. Anywhere between ten and you will 15% is retouched (you to boundary or convergent sides).
The new marly and siliceous limestones was accumulated regarding the Payre or Rhone Canals. Certain fragments of your cavern limestone was in fact amassed and simply retouched. Pebbles had been damaged otherwise designed. Flakes are numerous, thin, mainly cortical and you can quick, and you can brought in, for quartz. Not everyone is retouched. A few limestone cores inside the level Fa can not be refitted having flakes. The fresh peeling took place into the quick flat gravel and you will cores that have one or two secant surfaces.
Quartzite turned up because gravel and you will first and foremost because large and small flakes, obtained maybe along the Rhone Lake. The massive flakes was cortical or partially cortical. Smashing marks to the edges service a great play with having big factors. Just one portion would-be considered as a key or an excellent re-utilized busted bifacial device. Quick flakes you will are from the newest rejuvenation of hefty-duty tools or was in fact brought in to have unknown grounds, like with the huge basalt gadgets towards the flakes.
The massive flakes, flaked from large cobbles outside the webpages, try unretouched otherwise retouched since the higher unifacial or bifacial gadgets (peripheral, directed or transversal)
From the Bau de- l’Aubesier, almost the complete assemblage is actually flint, it might have been possible to acknowledge various sorts of flint and you may track her or him back once again to origin components regarding the area, and examine many features of any provider urban area who would determine hominins’ choice of even in the event (or just how much) for action [108, 109, 110, 111, 112, 113, 114]. Throughout accounts, a significant proportion of your own lithic assemblage could have been patinated to including an extent that the parts could only feel identified as becoming flint, no source is charged. Bringing these using the patinated bits, although not, during the membership J-J4 together, what causes 43.2% of one’s bits are either unfamiliar otherwise unidentifiable; inside account K-K2 these take into account 51.7% regarding parts.
