Upper Cretaceous deposits in the southern Grands Causses (France)

Since 1967, some Upper Cretaceous deposits have been discovered in the Gran ds Causses. In the course of our work, we have identified, analyzed and mad e maps of numerous previously unknown deposits in varied facies, stretching from the eastern Causse of Larzac to the Causse of Campestre. Bauxite, sit uated in contact with Tithonian limestone, is followed by sandy clay sedime nts. Then a thick layer of sandstone and marine fossil-rich limestone fossi lized a differentiated palaeotopography. This is then partially exhumed, le aving some trace of the Cretaceous continental cover. ((C) 1999 Academie de s sciences/Editions scientifiques et medicales Elsevier SAS.).
