摘　　要：大井矿区岩浆岩、赋矿围岩和矿石矿物的许多特点表明,大井矿床的形成经历过多期构造活动,成矿物质具多源性.用构造地球化学的观点分析该矿床的形成过程,认为在其外围找矿应综合考虑沉积-变质岩、次火山岩和构造破碎带控矿等问题.Lots of characteristics of magmatic rocks, ore-hosting rocks and ore-minerals in the Dajing miningarea demonstrate that the deposit in this area had subjected to a series of tectonic activities, with its oreforming substance introduced from various sources during its minerogenetic process. After an analysisof the mineralization process of the deposit from a point of view of tectono-geochemistry, the author believes that for ore exploration in peripheral region on the mining area, the stress should be put on sedimento-metamorphic rocks, subvolcanic rocks and tectonoclastic zones.
