ABSTRACT: The Suzette and Propiac-Condorcet diapirs of the Southern .Alps of France» emplaced along `"en echelon11 tensional fractures; of strike-slip fault, zones; which formed by the N-S compressional forces of the. Pyreneo-Provînctal plias« of the pre-Oligocene time., The Suzetle diapir has ultimately gained "SM sha|pes that. is. a, characteristic structure of subjected fault zones of tensional fractures., The Suzette diapir is overlained by the Oligocène» and the Propiac-Condorcet diapirs by the Miocene successions. Both, of these younger successions later were tilted and locally overturned by the reactivation of the diapirs.
