«HYDEN ROCK» ET «WAVE ROCK» (AUSTRALIE): DES CURIOSITES GEOMORPHOLOGIQUES EN TERRAIN CRISTALLIN

Jean-Noel Salomon

Abstract


Famous in Australia for their photogenic aspect, the sites of “Hyden Rock” and “Wave Rock” are part of the touristic circuit of the Perth region (SW Australia). They are original and spectacular forms developed in very old granite. Nevertheless, their interest is more than their aesthetic aspect and despite attempts of explanation by tourist brochures and tour operators, geologists remain unsatisfied as to their genesis. This note attempts to in part remedy that.


Keywords
