... sorption and immobilization of elements and is favourable for secondary enrichment in gold and silver. It leads to immobilization of elements that further form new mineral phases or become partitioned between existing phases. On the other hand, very high concentrations of water-soluble and oxidizable...

... to the association of VHMS deposits with seawater and deposition at or near the sea floor. SEDEX (medians of 23.88 ppm for Ag and 963.86 ppm for Pb) and VHMS (medians of 22.00 ppm for Ag and 320.41 ppm for Pb) pyrite is enriched in silver and Pb. Interestingly, Co and Ni in sulfide minerals, which have long been...
