摘　　要：围岩蚀变是在热液成矿过程中,近矿围岩与热液发生化学反应而产生的一系列物质成分和构造、结构的变化.在大宝山矿区围岩蚀变极为发育,不同的矿床有其特征的围岩蚀变,围岩蚀变直接影响各矿床的分布特点.本文分析了铜硫矿体与围岩蚀变的关系,从围岩蚀变的角度说明铜硫矿体分布特征和矿石类型,通过围岩蚀变的变化寻找相应的铜硫矿体.The alteration of wall rock means the changes in composition and structure of substance caused by the chemical reactions occurring between the hot liquids and the wall rocks near the ore body during the formation of the hot liquids. The wall rock alteration proceeded very well at Dabaoshan mining areas, with each ore deposit having its own character of wall rock alteration, and with the alteration directly affecting the distribution of the ore deposit. The relationship between the copper-sulfur ore body and the wall-rock alteration is analyzed in the paper. The distribution pattern of the copper-sulfur ore and the rock type in the ore are explained based on the wall rock alteration, and in turn the copper-sulfur ore can be pros- pected according to the character of the wall rock alteration.
