| 中文摘要: |
| 内蒙古翁牛特旗草原、农田浅覆盖区位于华北板块北缘，大兴安岭铜多金属成矿带的南段，是少郎河铅锌矿集区的重要组成部分。作者在内蒙古中东部草原荒漠浅覆盖区1：5万填图试点工作基础上，对少郎河地区铅锌多金属矿床进行了调查研究，并以小营子铅锌矿为典型矿床，探讨了控制区内铅锌多金属矿的主要地质要素。在典型矿床研究认识基础上，明确了区内控制铅锌矿的主要赋矿地层，探讨了小营子—敖包山一带铅锌矿的矿床成因，并建立了成矿模式。以模式找矿及就矿找矿理论为指导，以找矿预测为目的，利用综合填图方法，分析了小营子—敖包山一带找矿潜力，并圈定了2处重点预测区。通过地质、物探及钻探综合研究，揭露了覆盖层下隐伏赋矿层的分布特征，扩大了找矿远景区的范围，认为翁牛特旗浅覆盖区具有寻找铅锌多金属矿的巨大潜力，并开展了找矿预测研究，试图为下一阶段找矿勘查提供重要的基础地质支撑。 |
| 英文摘要: |
| Located in the southern section of the Da Hinggan Mountains copper polymetallic ore belt, the shallow covered area of the Wengniute Banner is an important part of the Shaolanghe lead-zinc ore concentration area. Based on the work of 1:50000 regional geological mapping in the desert and grassland over area of the Wengniute Banner, we conducted geological survey of the Shaolanghe lead-zinc polymetallic ore-forming belt, and then discussed the ore-controlling factors of ore-bearing strata, ore-forming rock bodies and ore controlling structures taking the Xiaoyingzi lead-zinc deposit as a representation in the western adjacent region of the study area. We also discussed the ore genesis and metallogenic model of the lead-zinc deposits in the Xiaoyingzi-Aobaoshan area. Guided by the theory of "modelling ore prospecting", we identified the ore-bearing layers and analyzed the prospecting potentiality in the Xiaoyingzi-Aobaoshan area. The distribution features of hidden ore-bearing strata under the overburden layers were revealed though comprehensive geological, geophysical and drilling research, with an important achievement of expanding the scope of prospecting area. Geological characteristics suggeste good ore-forming conditions and prospecting potentiality in the study area, and it is an important region for the next prospecting prediction. It is considered that the potential of searching for lead-zinc polymetallic deposits in the shallow coverage area of the Wengniute Banner is great, and this work is expected to provide an important geological support for the next prospecting in this area. |
