New Mineral Occurrences in Massive Sulfide Deposits from Mănăilă, Eastern Carpathians, Romania

The massive sulfide deposits (VMS) from Mănăilă are associated with the metamorphic formations of Tulgheș Lithogroup Bucovinian Nappes Crystalline-Mesozoic Zone in Eastern Carpathians, Romania. following types ore were identified: pyrite-polymetallic, pyrite copper, compact and precompact quartz-precompact copper. polymetallic mineralization consists pyrite, chalcopyrite, sphalerite, galena, subordinately arsenopyrite tennantite. especially quartz-copper mineralizations, have a distinct mineralogical composition compared to other metamorphosed mineralizations Lithogroup. These contain large amounts bornite chalcocite along chalcopyrite. Tennantite is abundant has up 3.57 wt.% bismuth. Wittichenite was identified for first time mawsonite as occurrence An unnamed mineral formula: Cu,Fe11Pb,AgS7 also identified, belonging sulfides group. pyrite-rich ores, located sericite ± quartzite schists covered by rhyolitic metatuffs, hydrothermal-sedimentary type greenschist facies. source would be retromorphic or metasomatic hydrothermal solutions that circulated through major fractures.
