This PhD aims to study caves and subterranean karst infillings deposits from Charente (Touvre catchment) as a memory of past climate and environments. From the concept of site effect, the two studied caves (Bois du Clos and Fuie) show an original recording of the regional palaeoclimatic conditions of the Middle-Upper Pleistocene and of the Holocene. The prominent role of the ghost-rock processe during the long geological time of Lower Cretaceous (45 Ma) was demonstrated by the study of three quarries, drilling and the young cave of La Fuie. This alteration process explains the genesis of labyrinthic caves and also the complexity of the Touvre aquifer which supplies the city of Angoulême. Indeed the large water reserve is situated into the p...
