Tectonic map of the Western Alps, showing distribution of HP ages for metamorphic rocks (modified after Rosenbaum and Lister 2005). White stars indicate the location of Pfulwe pass area, where eclogite facies rocks preserved pillow textures, the Triftji locality at the base of the Breithorn, and the Lago di Cignana coesite locality (LDC). Dent-Blanche nappe, Sesia zone and Pillonet klippe are considered as derived from the Cervinia microcontinent. Although the continental outliers were probably also part of Cervinia, they are designated as a separate unit. TGU Theodul Glacier Unit, LDC Lago di Cignana Unit, E. L. Etirol-Levaz sliver, Mt. E.
