摘要
地壳中可划分出五大类不同的成矿地质流体体系：①与大陆地壳中—酸性岩浆热事件有关的热液流体体系；②与海底基性火山活动有关的热液喷流流体体系；③与海相沉积盆地演化有关的盆地流体体系；④与区域变质作用有关（含与大型剪切带有关）的变质流体体系；⑤与地幔排气过程有关的深部流体体系。简要讨论了每个成矿流体体系的发生、演化、特征和成矿作用。并指出，成矿地质流体体系的时间—空间演化动力学轨迹实际上就是热液矿床的相继定位以及有关的矿床系列不断被完成的过程，这也就是我们所要认识的、矿床在时间和空间上的成矿规律。
In the present paper, ore forming geofluids in crust were classified into five fluid systems: (1) ore forming fluid system in connection with acid intermediate magmatic activity in continental crust; (2) ore forming fluid system in connection with submarine basic magmatic activity; (3)basin fluid system in connection with sedimentary basin evolution; (4) metamorphic fluid system in connection with regional metamorphism; (5) mantle fluid system produced by mantle. The occurrence, evolution, main features, and ore forming processes of each fluid systems were briefly discussed.
