The massive sulphide deposit is hosted within an ophiolitic sequence composed of calcschists with interlayered metabasites, micaschists, chloriteschists, quartzites and marbles, metamorphosed under eclogitic facies conditions (MODESTI, 2021). In particular, the ore deposit is interposed between Grt-Cld micaschists in the foot-wall and chloriteschists in the hanging-wall. The ore mineral association mainly comprises pyrite, chalcopyrite and pyrrhotite, along with sphalerite; the proportion of the three main ore minerals vary considerably in different specimens. The gangue minerals are dominated chlorite, followed by quartz, albite, carbonate, epidote, white mica and garnet. Thanks to a detailed micro-textural and geochemical study, supported by spot electron microprobe analyses and elemental maps of some trace elements (Co...
