Late Pleistocene evolution of Antelias valley (Lebanon): speleogenic approach applied on Kassarat cave system with implication of U/Th datations records.
Résumé
Lebanon landscape is characterized by tow karstic mountain chains with a variety of surface karstic forms as well as endokarstic network systems. A research project on Lebanon's karst geomorphology was conducted recently by EDYTEM laboratory CNRS-UMR 5204, France and Saint-Joseph University of Beirut and aims at reconstituting: i) speleogenic evolution based on geomorphologic indicators, ii) karstogenesis evolution related with the downcutting of the Mediterranean hydrographic network (Antelias river), iii) palaeogeographical stages of these valleys.
