Abstract The stratiform and vein-type mineralization of the Pollone deposit (barite and pyrite, with accessory galena, sphalerite and sulphosalts) displays an exhalative origin and a metamorphic imprint. Diaphorite (Pb1.87Cu0.03Cd0.03)Ag3.13(Sb2.81As0.16)S7.97, reported for the first time in the Apuan Alps, occurs both as exsolutions and as intergrowths in galena. It is part of irregular enrichments of quartz with galena, sphalerite and Ag-sulphosalts in the wall rocks of the "Galleria Preziosa" vein which were formed probably as a result of metamorphic remobilization.
