Discover the cave


Jean-Jacques DELANNOY

​Geomorphologist, Anthropo-geomorphologist 

With a PhD in geomorphology, he developed the morphogenic study of the caves. This approach, applied to different geodynamic contexts (the Alps, the Baetic Range, South Ardèche) underlined the diversity of underground archives and their relevance to palaeographic and palaeoenvironmental reconstitutions. This work, based on the systemic approach and high-resolution cartographic records, was then applied to the study of decorated and archaeological sites (Chauvet-Pont d’Arc Cave, Terre d’Arnhem, Papua New Guinea). In 2003, he set up the EDYTEM multidisciplinary laboratory (University of Savoie-Mont Blanc, CNRS, Ministry of Culture and Communication). 

As a member of the Chauvet Cave scientific team, he promoted the geomorphological study by distinguishing between the evolution of the cave before, during and after Palaeolithic inhabitation. The cartography of the cave floors, the study of the entrance area and the analysis of the anthropogenic modifiations, carried out in collaboration with the team, are based on the same principle as the morphogenic approach. Taken together with the datings and the 3D data processing, this enabled the group to establish the process and date of the cave's closure (in collaboration with Benjamin Sadier), the restitution of the prehistoric entrance (in collaboration with Benjamin Sadier and Stéphane Jaillet), and the ways in which the anthropogenic layout was built (in collaboration with Élisa Boche, Stéphane Jaillet, Jean-Michel Geneste and Benjamin Sadier). 

As a member of the Chauvet Cave Restitution Space Scientific Committee, he took part in outlining the content of the Pont d’Arc Cave and the Discovery Centre, and followed up on them once established. His involvement was focused on the restitution of underground landscapes, the state of the walls, and the morphologies of the cave. Particular attention was paid to the transfer of this knowledge to sculptors and ceramicists: this led to the creation of a card with the various features to be depicted and a textured 3D model of the cave.
