摘　　要：文章从断裂活动和热液流体迁移的热动力学角度阐述了金矿热液形成、迁移和富集沉淀的物理化学机理,得出了断裂活动不仅为金矿形成提供了储矿空间,更主要的是为金矿热液形成提供了活化热能和大量流体,为其迁移提供了动能,为其沉淀富集提供了有利的、多期多阶段的物理化学条件。Physiochemical mechanism of formation, transportation, concentration and precipitation of Au ore fluid is described on the basis of fracturing activities and thermal dynamics of formation and transportation of thermal fluid. Fracturing activities not only provide Au ore accumulated space but also the more important heat energy for activiation and formation of ore fluid dynamic energy of the fluid transportation, multiple-staged favorable physiochemical conditions for precipitation.
