1矿床地质特征东珺矿区位于中生代陆相火山盆地边缘的古隆起部位,区内构造以线性构造为主,旁侧次一级断裂构造较发育;区内出露的地层简单,大面积分布侏罗系塔木兰沟组地层,除侏罗系塔木兰沟组火山岩外,侵入岩不甚发育。矿体主要赋存于中侏罗统塔木兰沟组火山岩中,充填于NW向、NE向的张性裂隙中。矿
1 Geological Characteristics of Deposits Dongjun Mining Area is located in the paleo-uplift located on the margin of the Mesozoic continental volcanic basin. The structure in the area is dominated by linear structure, and the faults in the secondary subfamily are well developed. The strata exposed in the area are simple and have a large area of distribution Luo system tower Mulangou formation, in addition to the Jurassic Damulanggou volcanic rocks, intrusive rock less developed. The orebodies mainly occur in the volcanic rocks of the Taulangou Formation in the Middle Jurassic and are filled in the tensional fissures in NW and NE directions. mine
