必鲁甘干矿区位于天山—阴山内蒙地槽华力西晚期褶皱带阿巴嘎旗复向斜中段,查干敖包(必鲁甘干)倒转背斜核部。区内NE向断裂构造控制了印支期花岗斑岩体及特大型斑岩型铜钼矿床的分布。通过勘探查明主矿体延长2 300m,延深1 850m,平均厚度46.24m。铜钼矿赋存于花岗斑岩与硅质角岩内外接触带,赋矿岩石主要为花岗斑岩和硅质角岩。矿体形态以透镜状—似层状为主,属斑岩型铜钼矿。
The Drugan dry-mined area is located in the middle section of the Abagaqi synclinorion in the Trench-Yinshanian Inner Mongolia Trench-trending Fold Belt, and the Chagan Obo (Bilugan) reverses the core of the anticline. The NE-trending fault structure controls the distribution of Indosinian granite porphyry and extra-large porphyry Cu-Mo deposits. Through exploration, it was found that the main ore body extended 2,300m in depth and 1,850m in depth, with an average thickness of 46.24m. Copper-molybdenum deposits occur in the inner and outer contact zones between granite porphyry and siliceous horn rock, and the ore-bearing rocks are mainly granite porphyry and siliceous horn rock. Ore body shape to lenticular - like layer-based, is a porphyry copper-molybdenum ore.
