【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。本文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-敖包山一带的找矿潜力,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。
[Abstract]:The grassland of Wuniute Banner of Inner Mongolia is located in the northern margin of the North China plate and the southern section of the copper polymetallic metallogenic belt in the Daxinganling Mountains. It is an important part of the lead-zinc ore concentration area in the Shaolanghe River. On the basis of 1: 50 000 mapping in the desert shallow cover area of central and eastern Inner Mongolia, this paper investigates and studies the lead-zinc polymetallic deposits in the Shaolanghe area, and takes the Xiaoyingzi Pb-Zn deposit as a typical deposit. The main geological elements of lead-zinc polymetallic ore in the control area are discussed. Based on the study of typical ore deposits, the main ore-bearing strata controlling lead-zinc deposits in this area are defined, the genesis of lead-zinc deposits in Xiaoying Zi-Aobaoshan area is discussed, and a metallogenic model is established. Under the guidance of model prospecting and ore prospecting theory, with the purpose of prospecting and forecasting, the prospecting potential of Xiaoying Zi-Aobaoshan area is analyzed by using comprehensive mapping method, and two key prediction areas are delineated. Through the comprehensive study of geology, geophysical exploration and drilling, the distribution characteristics of the concealed ore-bearing strata under the overburden are exposed, and the scope of the prospecting far area is enlarged. It is considered that the shallow overburden area of Wuniuet Banner has great potential for finding lead-zinc polymetallic deposits. The study of prospecting and prediction is carried out in order to provide important basic geological support for the next stage of prospecting and exploration.
