The Jaduguda U (–Cu–Fe) deposit in the Singhbhum shear zone has been the most productive uranium deposit in India. Pyrite
occurs as disseminated grains or in sulphide stringers and veins in the ore zone. Veins, both concordant and discordant to
the pervasive foliation, are mineralogically either simple comprising pyrite ± chalcopyrite or complex comprising pyrite +
chalcopyrite + pentlandite + millerite. Nickel-sulphide minerals, though fairly common in concordant veins, are very rare
in the discordant veins. Pyrite in Ni-sulphide association is commonly replaced by pentlandite at the grain boundary or along
micro-cracks. 相似文献
