摘要
狮子山铜矿床是罗茨-易门-元江铜矿带上具有代表性的矿床。通过应用构造解析法，对区内的地质构造、控矿因素等研究后，提出了一些新的认识：（1）本区昆阳群应底层状无序变质岩系．在狮子山“花状”构造中，以发育三期（S1、S2、S3）面理为特征．（2）岩层除经历了一期与大区域上一致的区域低温变质作用外，在狮子山走滑剪切带中尚孟加了一期动力变质作用。（3）确定了4个世代的构造变形，首次确立了主潮构造为狮子山”花状”构造。（4）狮子山铜矿的成因类到底脆一韧性剪切带到铜矿。
The Shizi Mountain Cu deposit is a representative ore deposit in the Luoci- Yimen-Yuanjiang Cu deposit zone. According to the study of the geological structure and deposit -controlling factors, etc in this region by the structural analysis method, we put forward a series of new viewpoints as follows. (1) The Kunyang Group in this region belongs to a strati form disordered metamorphic rock series. And the Shizi Mt 'flower-like' structure. is characterized by the developed planeation S1, S2, S3 of 3 stages. (2) Besides a regional low T metamorphism in the rock bed, there is a dynandc metamorphism superimposed on the Shizi Mt strike-slip shear zone. (3) There are 4 structural deformation stages and we determine first that the principal one is that of the Shizi Mt 'folwer-like' structure. (4) The genesis of Shizi Mt Cu deposit be1onge to the type of Cu deposit in brittle- -ductile shear zone.
