摘　　要：工区位于额尔古纳中段的铜-铅锌-银-钼-铀成矿带.自上世纪80年代在该区发现化探异常以来,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,采用了大功率激发极化中梯装置和激发极化测深相结合的方法进行勘察.在12线758点布置了一个倾斜度为83°的钻井,并在100 m左右深度见到了侵染状矿体.证实了分析的正确性,达到了找矿目的.The work area located in the middle section of Eerguna metallogenic belt. Since the day when geochemical anomalies be found in 1980s,there is less production. According to the geologic and geophysical characteristics in the study area, we chose appropriate methods and technique, and accurately understanding the geologic and geophysical significance of the anomaly, obtaining a relative ideal result for Pb/Zn mine prospecting. By drill-hole exploration at point 758 in line 12, it is verified that the relative ideal commercial Pb/Zn mine occurred in the depth around 100m. The analytic reliability is confirmed and confirmation the work reaches its aim.
