This study concerns the management of the quartzite pebbles collected close to the site. Approximately fifty refits in a single series permit the reconstruction of the morphology of the core and the description of the technological treatment applied to it. The most complete refit series shows the coexistence of several methods of debitage on this raw material alone; but, also, their succession in the same block. The series provides evidence of a flexibility of concepts of debitage and evidence of dynamic relations between these concepts. Quartzite is the object of special treatment according to several criteria: economic, since flint is not available in the local environment of the cave; morphometric, the production is conditioned by the precise choice in the selection of the blocks; petrology, the nature of the material does not allow the knapper the same important liberty in knapping as flint permits.
