Grabens and horsts
WebAs the crust extends it fractures in series of fault planes, some blocks sink down due to gravity, creating long linear valleys or basins also known as grabens, while the blocks remaining up or uplifted produce mountains or ranges, also known as horsts. Fault scarps are exposed on the horst block and expose the footwall of the normal fault. WebUne montagne en blocs est causée par des failles dans la croûte terrestre qui forcent une région entre les lignes de faille à glisser l'une sur l'autre dans un processus connu sous le nom de rupture. Les roches qui s'élèvent sont appelées horsts, tandis que les roches qui plongent sont appelées grabens.
