高精度磁测在内蒙古官地铅锌矿勘查中的应用研究

Research and application of high precision magnetic survey in Inner Mongolia lead-zinc ore exploration in GUANDI

矿区位于区域性黄岗—孟恩陶勒盖NE向多金属成矿带的南西端,成矿地质条件优越。自上世纪八十年代发现矿化露头以来,一直没有找到主矿体。为了解决该区的找矿问题,在充分研究工作区的地质、地球物理特征前提下,采用了地面高精度磁测方法,取得了较好的效果。区内共圈定隐伏岩体2处,划分出断裂构造6条,具明显的切割关系,为寻找含矿空间提供了重要依据。

The mine is located in the area of Huang Gang- Meng Entao Tolgoi North East to the South West polymetallic metallogenic belt, Which ha,s good metallogenic conditions. Since the discovery of day when mineralized outcrops be found in 1980 s,no major ore bodies have been found yetthere is less production.To solve this problem,we attempted to conduct a geophysical survey in this area. In light of according to the geologic and geo with physical characteristics ofin in the study of area, we chose the ground high precision magnetic method, obtaining a relatively ideal result for mine prospecting obtaining. Find two hidden geological bodies, find six hidden faults, have obvious sequence, its the cutting relationship, it provides an important basis for the search of ore bearing space.
