Abstract: The neolithic levels of the rock-shelter “La Grande Rivoire” are composed of a multitude of sedimentary layers of very contrasting colours. Sedimentological analyses show that the fine fractions, mainly silty and rather strongly carbonated, have two main origins: on the one hand, an important accumulation of herbivores faeces due to the repeated penning of flocks (presence of calcite spheruliths, high concentrations of organic matter, high rate of phosphate), on the other hand, a large production of ashes from fire kindled directly on the d...
