一、矿区的地层、构造、岩浆岩1.地层矿区内主要为一套前震旦纪下辽河群绢云母石英片岩、石墨化薄层状长石石英片岩、薄层状长石英片岩、厚层状长石石英片岩及零星的大理岩、石英岩等.矿床均产于薄层与厚层状长石石英片岩接触处之层间裂隙中.石墨化片岩虽矿化广泛,但片理中矿液分散.品位低,不够工业要求.绢云母石英片岩因可塑性较强,不易形成较大层间裂隙,很少含矿.
1. Strata, Structure and Magmatic Rocks in the Mining Area 1. The strata are mainly composed of the Lower Liaohe Group sericite quartz schist, the graphitized thin feldspar quartz schist, the thin lamellar feldspar schist, the thick layer Feldspathic quartz schist and sporadic marble, quartzite, etc. The deposits are produced in the thin layer and thick bedded feldspar quartzite contact in the interlayer fissure. Graphitized schist has a wide range of mineralization, Scattered. Low grade, not enough industrial requirements. Sericite quartz schist due to plasticity, not easy to form larger cracks between layers, with little ore.
