【Abstract】 Abundant information of ore fluid inclusions or melting inclusions has been collected from many famous metallic deposits in China. On the basis of the authors’ studies in combination with related data from home and abroad, the ore fluids are classified into four types, namely mafic-ultramafic magma, granitic magma-volatile component-thermal water, thermal water and normal temperature water. Viscosity, saturability, immiscibility, solubility and some other physicochemical parameters of ore fluids seem to be important constraint factors for the formation of ore deposits. This paper makes an approach to genetic mechanism of some typical metallic deposits in China based on the researches into temperature, pressure, salinity and chemical composition of ore fluid inclusions from these deposits.更多还原
