摘要
夏日哈北铁多金属矿位于青海省都兰县夏日哈镇以北约5 km处,地处祁漫塔格-都兰造山亚带东段,区内断裂构造发育,岩浆活动强烈。在地表圈出8条矿带共27条铁多金属矿体,赋存于进水口岩群片麻岩段和城墙沟组地层中,受断层破碎带、碳酸盐岩和岩浆岩复合控制,为矽卡岩型铁多金属矿。通过对区内地质特征和控矿因素的分析,结合高磁异常,认为在已发现的矿体深部及大面积风成砂覆盖区,有较好的找矿潜力,值得进一步开展找矿工作。
The Xiarihabei iron polymetallic deposit is located in Dulan County, Qinghai Province, 5km north of Xiarihabei Town, in the east of the Qimantage-Dulan orogenic zone, with strong faults and magmatic activity in the region. 8 deposit belts with a total of 27 iron and polymetallie ore bodies were circled on the surface, hosted in the water inlet rock group gneiss segment and wall groove formation, controlled by the fault fracture zone, carbonate rock and magmatic rock com- pound, belonging to skarn-type Fe polymetallic deposit. Based on the analysis of geological characteristics and ore control- ling factors in the area, combined with the high magnetic anomaly, it is believed that the deep and large area and the sand- coverd area have good prospecting potential.
