摘要
内蒙古额尔古纳大地构造位于额尔古纳地块与大兴安岭成矿带重合部位,区内有得尔布干深大断裂从测区右侧穿过,成矿条件有利。区内矿产丰富,有小诺伊盖沟金矿、六卡沟铅锌矿、红水泉铅锌矿、煤矿等。格鲁其堆山铅锌矿位于以上金矿铅锌矿的中心位置,与上面的矿床(矿点)相距4～10 km,处于相同的大地构造环境,成矿条件类型相似。中生代时期,尤其是侏罗纪中晚期-白垩纪早期,地壳发生伸展运动,构造活动强烈,伴随较强烈的中酸性岩浆侵入和喷发活动,为区内多金属成矿提供了热动力、成矿流体和富矿空间。
The tectonic of Erguna, Inner Mongolia is located in the overlap region between the Ergun plots and Daxingan- ling metallogenic belt, with Delbugan deep grand fault crossing through the right side of the survey area, favorable minerali- zation condition. The region is rich in mineral resources, with the Xiaoyinuogaigou gold mine, the Liuksgou lead-zinc mine, the Hongshuiquan lead-zinc mine and coal mines, etc.. The Geluqiduishan lead-zinc mine is located in the center of the gold ,lead and zinc deposits, 4 - 10 km away from the upper deposit sites, in the same tectonic environment and similar metallogenic conditions. In the Mesozoic period, especially in the Late Jurassic - Early Cretaceous, crustal stretching move- ments occurred with intense tectonic activity, accompanied by strong acidic magmatic intrusions and eruptions, providing thermal power, the ore-forming fluids and enrich space for polymetallic mineralization in the region.
