The study of undercover karst systems and their morphology is difficult to assess using punctual geotechnical tools. Here we present a method using a geostatistical 3D reconstitution based on electrical resistivity tomography (ERT) data to assess the high variability of the karst. We applied this method on the Lascaux hill site (south-west France) in order to: (1) detect karst morphologies under a detrital cover (pinnacles, shelves, karrens); (2) redefine the limit between two limestone formations; (3) define the geometry of the limit between two domains: limestone and detrital materials.< Réduire
