近年来,在区域地质调查和金属矿产勘查中,遥感资料受到越来越多人的重视(成永生等,2007)。研究发现:中亚成矿域已发现的一些大型-超大型金、铜、铁等多金属矿床,如Muruntau巨型金矿床、Kounrad和Aktogai超大型铜矿床、Oyu Tolgoi超大型铜金矿床、查岗诺尔大型铁矿床等均与直径几千m至几十km的环形遥感影像关系密切(余学中等,2015),矿床往往产在环形遥感影像边部,个别矿 In recent years, more and more people pay more attention to remote sensing data in regional geological survey and metal mineral exploration (Cheng Yongsheng et al., 2007). The study found that some large-scale super-large gold, copper and iron polymetallic deposits have been discovered in the Central Asian mineralization, such as Muruntau giant gold deposit, Kounrad and Aktogai superlarge copper deposit, Oyu Tolgoi superlarge copper-gold deposit, Noor’s large iron ore beds are closely related to the ring-shaped remote sensing image with a diameter of several thousands to several tens of kilometers (Yu et al., 2015). The deposits are usually located on the edge of a ring-shaped remote sensing image,
