Lithotypes of the Barmet Shear Zone. a Marble with metabasite boudins wrapped by the S4 greenschist foliation). b Silicate marbles with basic bands displaying a mylonitic foliation (S4) at Cime P. Blanches. c Cornieule with cm-size cubic or parallelepipedal holes possibly after former sulphate (W of Mt. Prial). d Boudins containing long prisms of white carbonate, probably calcite pseudomorphic after aragonite (Cime P. Blanches). e Carbonate breccias with Gln gneiss clast (W of Mont the Prial) f Matrix rich in carbonate and phengite surrounding a Gln micaschist (crossed-polarized light).
