摘　　要：讨论了流体成矿作用及其机理，流体成矿系统可分为现代海底、陆相热水成矿系统、古代热水成矿系统。热水成矿作用机理主要有不同类型流体混合成矿、热水同生沉积成矿、热水一岩石（沉积物）交换作用成矿、液压致裂一水岩交换作用成矿等4种主要机理。Study on mineralization and mechanism of fluid process indicates that mineralization system of fluid process can be classifiedinto mineralization system of sea bed thermal fluid, mineralization system of continental thermal fluid and mineralization systen of ancient ther-mal fluid. The mineralization mechanism of thermal fluid process can be attributed into the of different fluids, contemporaneous sedimenta-tion, exchange of thermal fluid with wallrocks and hydraulic cruking - exchange of water with rocks.
