摘　　要：东昆仑之祁漫塔格成矿带是一个多金属多类型矿产富集带,是我国新的十大找矿资源潜力地之一.近年来,此带中的斑岩型铜钼矿找矿取得了新突破,成为本区找矿工作的一个新亮点.位于祁漫塔格成矿带东侧之骆驼峰地区有大量的物化探异常,已发现了斑岩型铜钼矿、夕卡岩型铁多金属矿及热液脉型铜铅锌多金属矿,共同构成了斑岩型铜钼矿的岩浆热液成矿系列.通过总结区域及骆驼峰矿区成矿地质特征,分析斑岩型铜钼矿找矿前景,认为该区具有形成斑岩型铜钼矿的良好条件,加大找矿工作力度有望取得较大突破.As a multi-type polymetallic mineral enrichment zone,Qimantage metallogenic belt in eastern Kunlun Mountains is among the new Top 10 prospecting potential regions in China.In recent years,a new breakthrough has been made in the prospecting for porphyry Cu-Mo deposits in the zone,which has become a new highlight of prospecting work in the area.There are a large number of geophysical and geochemical anomalies in Luotuofeng area located in the eastern Qimantage metallogenic belt,where porphyry Cu-Mo deposits,skarn-type iron polymetallic deposits and hydrothermal vein-type Cu-Pb-Zn polymetallic deposits have been found,forming the magmatic hydrothermal metallogenic series of porphyry Cu-Mo deposits.By summarizing the metallogenic geological characteristics of the region and Luotuofeng orefield,and analyzing the prospecting prospects of porphyry Cu-Mo deposit,it is considered that the area has favorable conditions for the formation of porphyry Cu-Mo deposit.It is expected that great breakthroughs will be achieved by strengthening the prospecting work.
