| 中文摘要: |
| 敖包吐沟脑矿床是大兴安岭黄岗—孟恩陶勒盖北东向多金属成矿带中一个典型的铅锌多金属矿床。通过地表填图、槽探揭露、物化探测量等工作手段,共发现8条矿化蚀变带,均赋存于满克头鄂博组地层中,呈NNW向条带状展布,宽5～25 m,长50～380 m,总体走向NW,倾向NE,倾角60°～80°；矿体呈脉状、细脉状产出,厚1～6 m,产状与蚀变带产状基本一致。岩石褐铁矿化、硅化、绿泥石化等蚀变发育,局部可见星点状孔雀石化。对矿区成矿地质背景、矿床地质特征、成矿条件、找矿标志及方向进行研究探讨,为矿区及外围进一步勘查找矿工作提供依据。 |
| 英文摘要: |
| Aobaotugounao is a typical Pb-Zn polymetallic deposit of North East Huanggangliang-Mengentaolegai Ore Belt in Inner Mongolia. By means of surface mapping, trench exploration and physical-chemical survey, eight mineralized alteration zones are found, which are distributed in the Manketou Ebo formation in NNW direction, with a width of 5-25m, a length of 50-380m, a general trend of NW, and a tendency of NE, the dip angle is from 60° to 80°, the orebody is vein-like and veinlet-like, and 1 to 6 m thick, and the occurrence is basically consistent with that of the alteration belt. Limonization, silicification, chlorolitization and other alteration are developed in the rocks, and starlike malachite can be seen locally. This paper studies the geological background、geological characteristics、ore-forming conditions、 prospecting marks and direction of ore deposit, provided the basis for further prospecting and exploration of the mine area and its periphery. |
