| 中文摘要: |
| 为查明内蒙古自治区额济纳旗大红山金多金属矿区地球物理特征以及区域成矿地质条件,采用激电中梯法在研究区内开展了1∶10000激电中梯测量和1∶5000激电剖面测量,共查明激电异常2处(JD1、JD2)。结合矿区内地质资料,分析2处激电异常区域和激电中梯剖面图,得出该多金属矿区内金属硫化物矿体是造成高极化率异常的主要原因,高极化率异常是下一阶段找矿工作的关键线索。相关工作为今后该区域以及相邻区域寻找类似矿床起到了一定的指导作用。 |
| 英文摘要: |
| IP Middle ladder survey at scale 1∶10000 and IP profile survey at scale 1∶5000 were carried out to make clear geophysical characteristics and regional metallogenic geological conditions of Dahongshan Au polymetallic mining district, Ejin Banner, Inner Mongolia Autonomous Region. Two IP anomalies(JD1 And JD2) are delinated. Based on geological data the two IP anomalies and the IP profile are analyzed showing that the metal sulfides ore body causes high polarizability anomaly. So the high polarizability is the key clue for further prospecting in the area and surroundings. |
