摘　　要：以地质演化为基础，从沉积－构造－岩浆－变质－成矿作用角度进行综合对比分析，提出煎茶岭—七里店和黑木林—峡口驿两大构造岩浆带对勉略宁地区矿床起主控作用， 认为各类型矿床成矿作用与先存基底岩石有成生关系， 将矿床形成时代统一在秦岭陆－陆碰撞时限范围， 对该地区地质找矿工作及矿床理论研究进行了讨论。Based on the geological evolution and from view of constrasting sedmentation structure magma metamorphism ore formation, conclusions are drawn out: the deposits in the Mian Lue Ning area are controled by the two main structure magma belts along JianChaLin to QiLiDian and HeiMuLin to XiaKouYi areas. The deposits have genetical associations with the old basic rock and formed during the period of QingLin continent to continent collision.
