流体不仅是地球的物质组分,而且是最活跃的组分,是地球几个圈层间质量、能量交换最直接的媒体。地质流体是一定地质作用的产物,而矿床的形成过与特定地质构造背景下地质流体的产生、运移和聚集有着密切联系。不同成矿流体的成矿机制各有差异。岩浆热液因温度降低、压力减小等因素使热液中成矿物质达到过饱和,从而产生矿质沉淀;沉积盆地含矿热卤水流体在热对流、沉积压实等作用下运移、充填、聚集;与海底基性火山活动有关的现代大洋海底热液形成硫化物矿床;地幔流体的
Fluid is not only the material component of the earth, but also the most active component. It is the most direct media for the exchange of mass and energy between several circles in the earth. Geological fluid is a product of certain geological effects, and the formation of ore deposits is closely related to the generation, migration and accumulation of geological fluids in a given geological structure. Different ore-forming fluids have different metallogenic mechanisms. Magmatic hydrothermal fluid due to lower temperature, pressure and other factors over the hydrothermal mineralization material to achieve supersaturation, resulting in mineral deposits; sedimentary basin ore-bearing hot brine fluid in the convection, sedimentation and compaction under the action of migration, filling, Gathering; the modern oceanic seafloor hydrothermal fluids associated with seabed basic volcanic activity form sulfide deposits; mantle fluid
