摘　　要：大别山地区分布有一定数量的中酸性小岩体，在动力变质作用下，岩体本身及围岩发生钾化、硅化等热液蚀变现象。热液蚀变与钼、铜等多金属矿化关系密切，不同的蚀变类型可伴随不同的矿化现象，而热液蚀变往往具有分带性。探讨热液蚀变及其与矿化的关系，对普查找矿有借鉴作用。A few small neutro-acidic rocks are distributed among Dabie Mountain area, under the dynamic metamorphism. Potassium, silicification and other hydrothermal alteration phenomena occurred in rocks themselves and the surrounding rocks. Hydrothermal alteration is closely related to molybdenum, copper and other metal mineralization. Different alteration types may be accompanied by different mineralization, while the hydrothermal alteration divided into different zones. Explore hydrothermal alteration and its relationship with mineralization has great significance with census prospecting.
