Abstract:Oreforming fluids related to the magma system can be divided Intermediateacid according to fluid mineralization into silicate melt formed in the acid magmatic slage, the mixture of silicate melt and its exsolved hydrothermal fluids during the transitional stage from silicate melt to hydrothermal fluids hydrothermal exsolved from the Intermediateacid Orefluids Melts, and migmatized fluids formed during the formation Oreforming of granites migmatitization of metamorphic rocks. The acid magma system mainly provides heat and a part of ore sulstances and the heat provided ly it drives sulsurface water to leach the country rocks and extract ore sulstarces from the country rocks, thus forming sulsurface hydrothermal ore flids.On the basi S of these studies, detailed trace element geochemical characteristics of the different fluids and their Alovementioned Oreforming controls on mineralication are discussed.
