Limestone deposit in hydrothermal areas
NettetTrace amounts of Bi-and/or Te-bearing minerals are recorded in many Early Cretaceous hydrothermal gold deposits in the NCC (Gu et al. 2003;Bi et al. 2011;Zhou et al. 2011;Li et al. 2006Li et al ... NettetThese results indicate that the effect of the hydrothermal alteration were negligible in the generation of high-purity limestone in deposit scale. Whereas, the carbonate rocks can be divided texturally into two groups on the basis of an oxygen isotope ratio; the massive-textured or well-layered samples (>15 ), and the layer-disturbed (or layer-destructed) …

We address controls on Co and Ni distribution, based on their solubility in hydrothermal fluids as functions of pH, ƒO 2 and T, in two end-member types of sulphide deposits in Bergslagen, Sweden. Oxidized hydrothermal fluids, as have been suggested for the formation of the Zinkgruvan deposit, would efficiently transport Co and Ni in …
