This project is based on taphonomic observations carried out in the Chauvet cave (Ardèche). From the start of the studies, some walls affected by rubefaction provoked by the heat of some fires had been located in some areas. Relative chronology data and indirect dating helped to link this facies to the Aurignacian culture. Thermoluminescence analysis of rubefacted rock samples shows temperatures of at least 300 °C. Several hypotheses may be suggested to identify the function of these fires: lighting, heating and/or colourants production (wood coals). To discuss this, we offer to set some experimental fires in an underground quarry, combined with a set of environmental measures. They aim to firstly understand the working of a fire in an underground environment and its impact on a wall. The researchers will then try to get closer from the geological context of the Chauvet cave conducting experiments on an artificial wall made with Urgonian limestone blocks coming from Ardèche.
