摘要: 青海省祁漫塔格成矿带位于东昆仑造山带北西段，带内以往开展了以铁为主的找矿工作，发现一批矽卡岩型中型矿床。近年来带内找矿取得了重大突破：①发现一种新类型矿床——“虎头崖”式层控型大型多金属矿床；②低缓磁异常区多金属和铁矿找矿效果显著，发现四角羊-牛苦头大型多金属矿床，野马泉矿区多金属矿规模达到中型，尕林格矿区发现深部厚大的铁矿体。在系统地综合总结这些成果的基础上，探讨了找矿新进展的意义，划分了3处成矿远景区，并初步讨论了各成矿远景区内进一步找矿的方向。Abstract: The Qimantage metallogenic sub-belt is located in the northwest of the East Kunlun orogenic belt, Qinghai Province. Many medium-sized skarn type deposits have been found during the ore prospecting. Recently, ore prospecting progresses have been achieved as follows: ①A new type-Hutouya large-scale layer-bound deposit has been found; ②Sijiaoyang-Niukutou large-scale polymetalore deposit, Yemaquan polymetalore middle-sized deposit and Galinge deep-seated ore bodies have been found in low geomagnetic anomaly areas. It is suggested that Binggounan-Hutouya, Yemaquan-Galinge and Changshan-Shaqiu are three major target areas for further prospecting.
