| 摘 要： | 青海省都兰县丘吉沟铜矿位于东昆仑造山带，柴达木盆地南缘，该区构造发育，岩浆活动频繁，成矿远景较好。由于丘吉沟铜矿为近年来新发现的矿体，对其开展的研究相对较少，矿区内找矿方向不明确，制约了矿山的找矿与生产工作。为了指明区内的找矿方向，此次通过对丘吉沟铜矿开展激电中梯地球物理勘探的研究，圈定成矿预测靶区，为矿山的下步工作指明方向。通过研究发现:激电异常形态受EW 与NE向断裂构造控制，与构造展布相一致，构造交汇部位或构造的中心部位是异常的高值区域，同时也是找矿的有利部位；此次研究共圈定3个物探异常区，其中Ⅰ级异常区2处，为QD02、QD03物探异常区；Ⅱ级异常区1处，为QD01物探异常区。研究结果将为区内找矿指明方向。

| Abstract: | The Qiujigou Copper Mine in Dulan County，Qinghai Province was located in the East Kunlun Orogenic Belt，on the southern margin of the Qaidam Basin.The area was well-developed with developed structures，frequent magmatic activities and good mineralization prospects.Since the Qiujigou copper mine is a newly discovered ore body in recent years，relatively few studies have been carried out on it，and the prospecting direction in the mining area is not clear，which restricts the prospecting and production of the mine.In order to point out the direction of prospecting in the area，this time through the study of the IPZ geophysical exploration of the Qiujigou Copper Mine，the target area for the prediction of mineralization was delineated and the direction for the next step of the mine was pointed out.Through research，it was found that the abnormal shape of induced polarization was controlled by the EW and NE trending fault structures，which was consistent with the structural distribution.The structural intersection or the center of the structure was an abnormally high-value area，and it was also a favorable location for prospecting；this research a total of 3 geophysical prospecting anomaly areas were delineated，of which two were the first-level anomaly areas，which were QD02 and QD03 geophysical anomaly areas；and the second-class anomaly area was one，which was QD01 geophysical anomaly areas.The research results would point out the direction for prospecting in the area. |
