Détermination et origine géologique de la matière première de l'industrie lithique du site magdalénien du Rocher de la Caille.

Abstract : The raw materials used by the Magdalenian groups in Le Rocher de la Caille site belong to the great classes of rocks: sedimentary and crystallin. Few micro analysis made by the mean of thin slides concerned volcanic rocks. Most of them were mainly taken in the local place, gathered near the site or within ten kilometers (pebbles in crystalin and granitic rocks coming from deposits of the Loire, schist plates which perhaps are coming from outcrops of schist from Bully, situated to 9 km upstream, coloring materials). On the other hand, the different flints are coming from several seats, some of them are 10 to 40 km apart from the site, downstream to the river, others are much more distant, to 180-200 km at North/North-West. But the origin of some of them, one is very near of the famous flint of Grand Pressigny, cannot be determined. Finally, the soapstone could be come from the region of Haut Allier distant of 50 to 80 kms from Rocher de la Caille, by the shorter distance.
