Alpe La Piana, Premosello Chiovenda, Val d'Ossola, Provincia del Verbano-Cusio-Ossola, Piemonte, Italia
Hercynite and augite crystals are hosted in a mafic/ultramafic rock belonging to the Ivrea-Verbano Zone (pre-Hercinian basement of the South Alpine realm) but they are in close spatial proximity of the tectonic contact with the overlying Austro-alpine Nappe called Sesia-Lanzo Zone.
A bit tricky, in such context, may be the origin of vugs where the big and relatively well formed crystals are apparently free standing. A guess could be that late-stage Fe-Mg carbonates were filling the vugs, later removed by leaching.
