Succession de subfacies m�tamorphiques en Vanoise m�ridionale (Savoie)

Abstract

The Southern Vanoise is localized in the internal part of the Western Alps, in the Brianconnais zone. In Vanoise the following units can be distinguished (Fig. 1): a pre-hercynian basement (micaschists, glaucophanites, basic rocks), a permian cover (micaschists) and a mesozoic-paleocene cover (carbonate rocks). This area has been affected by the alpine metamorphic event characterized here by high and intermediate pressure facies. The rocks paragenesis are often unbalanced.
