摘　　要：吉林省大横路钴铜矿床赋存于辽吉早元古宙裂谷中段、老岭背斜的南翼，具体层位为老岭群大栗子组的中部岩性段，属于一套浅变质岩系。该岩系由于受构造作用影响产生了明显的断裂和褶皱。特别是褶皱核部及转折端，是矿体聚集的重要空间，矿体形态产状与褶皱形态基本一致。该区的变质变形作用对成矿物质的活化迁移及富集具有决定性作用；而后期岩浆活动。Dahenglu Co Cu deposit is located in the middle section of Liaoning and Jilin Early Protorozoic rift, south flank of Laoling anticline, lithologically, the host rock for this deposit is the middle section of Dalizi Formation, Laoling Group, which consists of a suite of lightly metamorphosed rock series. This rock series, affected by structural activities, developed distinct faults and folds. The orebodies mainly exist in the core or bend point of the fold and the shape and occurance of the deposit generally coincide with the fold. Metamorphism in this area was the key factor to the emigration, activities and enrichment of ore forming material; while the later magmatic activities are just factors of super imposement and reformation to some extent.
