Abstract

The use of transport models to describe the fractionation of oxygen isotopes between water and rock in order to interpret the oxygen-isotope composition of carbonates in gold-ore deposits in volcanic belts in Siberia and the Far East has shown that the gold ores were formed by convective movement of meteoric waters around hot magmatic bodies. The most likely deposition mechanism was redeposition at a redox boundary arising from the movement of oxidized meteoric water through rocks showing reducing behavior because of enrichment in organic matter at earlier stages in the development of the system. -from Journal summary
