These are (1) the quartzbearing polymetallic sulfide type, (2) the carbonatebearing polymetallic sulfide type, and (3) the baritefluoritesulfide type. We investigated the genesis of each veintype using RbSr sphalerite geochronology, SmNd fluorite geochronology, and Pb, Sr, and Nd isotope systematics of ore and gangue minerals.

Volcanogenic massive sulphide (VMS) deposits, also known as volcanicassociated, volcanichosted, and volcanosedimentaryhosted massive sulphide deposits, are major sources of Zn, Cu, Pb, Ag, and Au, and significant sources for Co, Sn, Se, Mn, Cd, In, Bi, Te, Ga, and Ge. They typically occur as lenses of polymetallic massive sulphide that form at or near the seafloor in submarine volcanic ...
This layer is enriched in Ni (up to wt %), Mo (up to wt %), and U (up to 595 ppm), but its genesis is still controversial. Here we report the first direct observation of uraniumbearing minerals and their radioactive effects on the surrounding matter in the polymetallic sulfide ore.
magmatic sulfide deposits where the principal ore mineral is pentlandite [(Ni,Fe) 9 S 8]. The ionic radius of divalent nickel is close to that of divalent iron and magnesium, allowing the three elements to substitute for one another in the crystal lattices of some silies and oxides. Nickel sulfide deposits are generally associated with iron ...
