Analyse 3D de la conservation du remplissage détritique de la grotte Roche (Vercors, France)

Abstract : 3D analysis of the conservation of the Detrital Deposit of the grotte roche (vercors, france). An important excavation (1993-2008) has been digged in the “grotte Roche” (Vercors) which led to the discovery of new galleries (1608m) and a major stratigraphic profile. This profile displays interesting sedimentary forms such as progradation, crisscross deposits, erosional surfaces… and interest is as much aesthetic as scientific or educational. A non-destructive analysis, based on a series of laserscanning surveys and field observations, allowed a better understanding of the dynamics of such a deposit and the ways of its erosion associated with excavation and current visitors frequentation. The numerical results show that while the impact of caving practice is not negligible, it should be balanced with the discovery of the underground object and its scientific and educational value. This type of study shows that today it is important to carry on further assessment on the knowledge and the preservation of the underground environments, including their deposits.
