Costa Grusniera (Monte Nebin; Colle di Sampeyre), Sampeyre, Provincia di Cuneo, Piemonte, Italia


Rodingite outcrop located between 2100 and 2200 m a.s.l. at Costa Grusniera, along the north slope of Monte Nebin, above the road leading to Colle di Sampeyre (about 2 km before the pass).

This locality has yielded red crystals of grossular and emerald-green crystals of vesuvianite up to 1 cm. Stella (1895) mentions also the presence of pale green rodingites composed of "uvarovite" garnet. Although there are no analytical data for this garnet, it is likely attributable to green grossular or andradite. Small crystals of green andradite have been recently found (Piccoli et al., 2007). The presence of green omphacite is known for a long time in the embedding serpentinite.

Furthermore, in this area metamorphic veins occurring in fractured serpentinites usually contain various fibrous minerals (carlosturanite, antigorite, diopside, garnet, etc.), of which carlosturanite and diopside are the main constituents. Carlosturanite generally occurs as long fibres oriented either parallel or perpendicular to the vein selvages. Fibrous diopside, garnet (andradite with fibrous habit) and antigorite are intergrown with carlosturanite. Carlosturanite can be partially replaced by chrysotile and/or brucite (Belluso & Ferraris, 1999; Groppo & Compagnoni, 2007).
