Monte Avic


Mountain (3,006 m), part of the Mont Avic Natural Park.

Ultramafites with late-metamorphic veins.

It consists of a ca. 200 km2 body of ultramafic rocks (Mont Avic ultramafic unit) surrounded by metabasites, metasediments, and continental slivers. The ultramafic rocks consist of variously foliated serpentinites that locally include lenses of Al–Mg and Fe–Ti metagabbros and dikes of metarodingites. The serpentinite in contact with the gabbro lenses is strongly foliated and can be referred to as a serpentinite schist.
The analyzed samples Sav2105 and Mez211002 belong to the Savoney and Mezove units, respectively. The Sav2105 sample is from a coherent hectometric eclogitic metabasite body located at the top of the Savoney unit, approximately 200 m below the tectonic contact with the Glacier–Rafray unit. The Sav2105 sample is considered the reference eclogite for the study area. The reference eclogite was not sampled in the Mezove unit because most blocks in this unit were probably affected by fluid–rock interactions and are highly retrogressed. Below the Savoney unit, the Mezove unit is a shear zone consisting of foliated serpentinite and meter- to decameter-scale lenses of blueschist to eclogitic Fe–Ti metagabbros, Al–Mg metagabbros, metabasites, and metasediments. Eclogitic metabasites are former basalts or Fe–Ti gabbros. Wherever eclogitic metabasite lenses are embedded in Al–Mg metagabbro, they are interpreted as ancient dikes, sills, or igneous enclaves. The metabasite lenses are partly retrogressed in blueschist- to greenschist-facies conditions, but the eclogitic assemblage is preserved in most lenses. The four samples Mez211002(A), Mez211002(B), Mez211003, and Mez220801 are from the inner part of a decameter-long eclogitic metabasite block surrounded by foliated serpentinite. A 10 cm thick chlorite-rich blackwall develops at the contact between the lens and the host serpentinite. The brecciation structure is visible in the inner part of the lens, while the outer part of the lens preserves the eclogitic structure without brecciation. The transition between the inner brecciated part and the outer non-brecciated part is not exposed.
