金川有色金属公司一矿区主要由露天矿与龙首矿(坑采)组成。该矿区位于龙首山与戈壁滩的交界处,河西走廊北侧龙首山东段的东北坡。由于经受多期构造作用断裂,特别是走向断裂发育最为显著。含矿超基性岩沿深大断裂次一级断层上侵于前震旦纪混合岩、片麻岩、白云质大理岩中,岩带长达6.5公里左右,由于断层的错动或间隔分成四个矿区,其中一矿区出露地表,发现和勘探最早。一矿区矿体长约1300米,宽约10～175
Jinchuan Nonferrous Metals Company, a mining area mainly by the open pit mine and the first mine (pit mining) composition. The mine is located at the junction of Longshe Mountain and Gobi Desert and northeast slope of Longshang Shandong in the north of Hexi Corridor. Due to the multi-stage tectonic fracture, especially the strike to the development of the most significant. The ore-bearing ultrabasic rocks invaded the pre-Sinian mixed rock, gneisses and dolomitic marble along the second-order faults of deep-seated faults. The rock belts are up to about 6.5 km in length and are divided into four due to fault dislocation or interval A mine, one of the mine exposed surface, the earliest discovery and exploration. A mine ore body length of about 1300 meters, a width of 10 to 175
