Typical facies of the Evolène Series breccias. a Matrix-supported dolomitic breccia: clasts are mainly dolomitic; matrix is dark and calcarenitic [599′460/267′340]. b Clast-supported polymict breccia [595′370/101′930]. Main clasts lithologies: pure quartzite (Qtzt), quartzschists (Qtz-sch), metabasites (Met) identical to those of the Métailler Fm. (Mont Fort basement), dolomites (Dol). c Clast-supported coarse polymict breccia. Block fallen from the Pointe du Vasevay southern face [593′810/097′240]
