| 摘 要： | 利用可控源音频大地电磁法(CSAMT)资料与构造解析相结合的方法,确定月山—黄土山背斜的构造形态,并绘制闪长岩岩体和月山组地层顶面等高线图。通过对比分析乌珠尖探区与邻区的CSAMT剖面特征,对乌珠尖勘探区的CSAMT剖面进行重新解释,提出该区有利的勘探部位。研究表明:1月山地区CSAMT剖面低阻带内没有矿体,高阻背景下的"V"型低阻异常带和陡降带是有利的成矿部位;2乌珠尖西南部是有利的勘探区块,并在该区预测了2个有利勘探钻孔;3乌珠尖探区与朱冲矿区位于月山—黄土山背斜倾伏端的两翼,在构造部位和成矿条件上具有相似性,是成矿的有利构造部位。

| Abstract: | With the combined application of CASMT data and tectonic analysis，the tectonic features of Yueshan - - Huangtushan anticline were ascertained． And the superface contour maps of the diorite rock masses and the Yueshan strata were drawn． Besides，the CSAMT profile of Wuzhujian exploration area was redefined by com- parative analysis of CSAMT profile characteristics of the Wuzhujian exploration area with its neighboring areas． In the end，advantageous exploration sites of the areas were made clear． The results show that ①there were no ore bodies within the low- resistance belts of the CSAMT profile of Yueshan area; and the V- shaped low- resistance belts of high- resistance zones and the sharp- drop belts were the favorable metallogenic places; ②the southwest areas of Wuzhujian were the favorable exploration blocks and two favorable prospecting holes were predicated in these areas． ③lying in the wings of the Yueshan - - Huangtushan anticline pitch ends，respectively，the Wuzhujian exploration area and Zhuchong mining areas resembled each other in tectonic position and metallogenic condition，and they are favorable tectonic positions for mineralization． |
