摘　　要：通过对灵山沟金矿围岩蚀变带特征的研究,阐明了灵山沟金矿围岩蚀变以碱交代为主,成矿热液为壳源深熔花岗岩浆演化期后热液,并指出围岩蚀变的发育程度与金矿化有密切的关系。On the basis of the study of the features of wall rock alteration zoning in Lingshangou gold deposit. It is indicated that the alkali-metasomatism played the leading role in wall rock alteration and the ore-forming fluid was from post magmatic hydrothermal soluion crust-derived anatectic granite .and the developing degree of wall rock alteration is closely related to gold mineralization.
