摘　　要：南坡铜矿为典型的"砂岩铜矿",赋矿岩层主要为上白垩统曼宽河组第二段(K_2m^2)灰白色岩屑石英砂岩。对其矿石的主量、微量及稀土元素含量分别与围岩的主量、微量及稀土元素含量特征进行对比,前两者主量、微量含量变化不大,后者稀土元素含量有所差异。Nanpo Cu deposit is a typical ＂san dstone Cu deposit＂. The main ore-bearing rock bed is Upper Cretaceous Mankuanhe Formation Member 2（ K2m^2） gray white lithic quartz sandstone. According to the comparison of major,minor element,REE of ore with those of wall rock,the REE content is different each other whereas the former 2 are not very different.
