Speleogenesis and Evidences Tectonic into Lakhssas Karst System (Western Anti-Atlas, Morocco)

摘要

This study aims to highlight evidences of tectonic and geodynamic features within Lakhssas high plateau karst area (Moroccan Western Anti-Atlas), using an original approach based on geospeleothems analysis.?This work is organized by the speleogenesis process, controlled by tectonics and interference of karst intrinsic parameters.?Regarding the first issue, a multi-layered study compiling inventoried speleological spaces with tectonic field data analysis then with lithological, hydrogeological and geomorphological features, has demonstrated that speleogenesis processes are deeply controlled by tectonic framework so described as “speleotects”. Subsequent studies in terms of sedimentology, geomorphology, hydrogeology and dating deposits, are planned to ground those conclusions.
