Vallone delle Forciolline, Pontechianale, Provincia di Cuneo, Piemonte, Italia


Along all the right side of Vallone delle Forciolline between Cresta Ticino and the Berardo Bivouac, Monviso SW ridge, an inverted ophiolitic stratigraphic sequence is exposed.

The sequence consists of: a basal level (a few tens of metres) of completely serpentinised peridotites; a gabbro complex (maximum thickness about 500 m); and a basaltic cover with pillow structures (about 500 m).

The most interesting portion of the ophiolitic sequence is the gabbro complex which is cut by a swarm of basaltic dykes, local1y so abundant as to suggest a "sheeted dyke complex". Most of the gabbro is massive, but lower part is locally layered displaying an alternation of cumulus troctolites (serpentinised), clinopyroxenites, and mela- to leucogabbros or anorthosites. The entire ophiolitic sequence shows a complicated Alpine metamorphic overprint, in which two main episodes can be recognised: the first is characterised by the widespread occurrence of zoisite and almandine-rich garnet and by incipient development of omphacite and glaucophane; the second is characterised by the development of greenschist-facies mineral assemblages with albite, chlorite, actinolite, epidote.
