Geological Characteristics and Geophysical Prospecting Signs of Gold Mine in Pengboshan area, Inner Mongolia

  • 摘要: 蓬勃山地区位于内蒙古自治区额济纳旗北西部,处于北山成矿带东段。石炭系绿条山组与白山组为主要赋矿地层,金矿化类型为石英脉型,石英脉产出受断裂构造控制。工作组对蓬勃山地区1、2号测区展开激电中梯测量工作,发现数条规模较大的高阻异常带,暗示着其下隐伏石英脉,视电阻率在600~1200 Ω·m为识别隐伏石英脉的物探标志。多数高阻异常带并不具有明显的视极化率异常,因此其异常表现为无矿或弱矿化石英脉,但在1号测区的Ⅰ号高阻带出现较高的视极化率异常,具有高阻高极化异常特征,推测该隐伏石英脉可能含有较多的金属硫化物,具有较好的找矿前景。
    Abstract: Pengboshan area belongs to eastern Beishan metallogenic belt, and located in the west of Ejina area, Inner Mongoulia. The Carboniferous Lvtiaoshan and Baishan Formation are primary ore layers, the type of gold mineralization is quartz vein, whose production is controlled by fault structures. Induced polarization intermediate gradien survey was carried out in No.1 and No.2 testing area, and many large-scale high resistivity anomaly belts have been detected, which indicates the existence of concealed quartz veins. Apparent resistivity of 600 to 1200Ω.m is the geophysical prospecting symbol for finding those concealed quartz veins. Most of the anomaly belts don't have obvious abnormal apparent chargeability, thus the anomaly is reflected as barren or weak mineralized quartz vein. However, high apparent polarization is found in No.1 testing area, with the characteristic of high resistivity and high polarizability. Therefore, we predict that the concealed quartz vein may contain considerable metal sulfides, and could have preferable potential in further prospecting work.
