Gold mineralization happens in the hydrothermal fluids of nonequilibrium condition and of the unsaturation and unsteady state of the solute gold , the deposition gold is enriched in the amorphous and crystalline sulfide phases . There are different Au mineralization effect and characterizing mineralization bodies in the upflow zones and spring ponds of the boiling spring , stream spring and hot spring fluids ; reflecting the varied mineralizing actions . It is demonstrated that thermophilic microbe especially sulfate_reducing bacteria are the internal dynamic role which make the oxidation_reduction of - or Au(S 2O 3) 2] 3- and Au_sulfide precipitation from the hydrothermal fluids. %K boiling spring %K stream spring %K gold metallogenetic geochemistry %K microbral mineralization %K mineralization effect
