内蒙古自治区鄂伦春旗宜里农场九队铜钼矿床地质特征及找矿远景

The geological characteristics and ore prospecting of Yili farm Judui copper molybdenum ore deposit in Elunchunqi, Inner Mongolia Autonomous Region

内蒙古自治区鄂伦春旗宜里农场铜钼矿是在1:5万水系沉积物测量基础上进行选区,发现了总面积超过10km2的Mo、Cu、Bi、Ag、Pb、Zn组合异常。通过进一步地质填图工作及1:1万综合物化探测量工作,发现了钼化探异常及激电异常。通过对异常进行槽探揭露,发现Ⅰ号钼(铜)矿体,该矿体类型为斑岩型铜钼矿床。矿体主要沿岩体与地层接触部位及构造发育部位分布,受构造及热液控制,近矿围岩蚀变较强。因此通过对该区地质条件分析,认为该区寻找此类型矿床前景具大,对今后大兴安岭成矿带寻找此类型矿床具有一定的指导意义。

the exploration target area of Yili farm copper-molybdenum ore deposit in Elunchunqi, Inner Mongolia Autonomous Region is determinated on the basis of the 1：50 000 stream sediment survey, Mo, Cu, Bi, Ag, Pb, Zn combination anomaly that total area is more than 10 km2 is founded.Mo geochemical anomaly and induced polarization anomalies is founded, through further geological mapping and the comprehensive geophysical and geochemical survey work of 1：10 000.No. 1 molybdenum （copper） ore body is founded through the trenching revealed abnormals. The ore body mainly distributes along the contact part of the rock mass and strata as well as structural development area, it is controlld by the structures and hydrotherm, the wall rock alteration near ore is stronger. By analyzing the geological conditions in this area, it is believed that this type of ore deposit is of great prospect in this area, which has certain guiding significance for the future prospecting of this type of ore deposit in Daxinganling metallogenic belt.
