一、矿区地质简述矿区位于辽东地块,由于受多期构造旋廻影响,因而构造、岩浆活动均非常复杂.事实汪明,辽东地块在前震旦纪经过呂梁运动以后,虽基本上已形成稳定的地块,但由于受后期构造运动影响,在古老的变质岩、混合岩与岩浆岩里,产生很多深大断裂,并随之有酸性、中性、硷性以至基性-超基性岩等各种岩 I. Geological Description of the Mining Area The mine is located in the Liaodong block and due to the influence of multi-stage tectonic rotation, the tectonic and magmatic activities are very complicated. The fact that Wang Ming and Liaodong parcels basically formed after Lvliang movement in the Pre-Sinian However, due to the influence of the later tectonic movement, there are many deep faults in ancient metamorphic rocks, mixed rocks and magmatic rocks with consequent acidic, neutral, alkaline and even basic - ultrabasic Rocks and other rocks
