“…These are located within the Mandanici Unit, consisting of marble layers and graphitic schists with intercalation of ankerite, associated with fluorite, barite, galena and pyrite. Above and laterally to marbles, Cu-Sb-Ag-As, Ni and Bi, with traces of Pb, Zn, W and Au sulphasalt-sulphide mineralizations are present [28], in mineral phases, such as galena, pyrite, chalcopyrite, sphalerite, pyrrhotite, arsenopyrite, the tetrahedrite group of minerals [(Cu,Fe,Ag,Zn) 12 Sb 4 S 13 ] stibnite [29], and scheelite associated with tourmaline [30,31]. Here, a hydrothermal system is recognised along the Tyrrhenian (Terme Vigliatore area) and the Ionian (Ali Terme area) coasts.…”
