摘　　要：在系统分析区内成矿条件和区域成矿特征的基础上,提出海相火山岩型、接触交代型(矽卡岩型)、变质(包括沉积-变质)型、沉积型(含喷气-沉积型)、构造蚀变岩型等是该区的主攻矿床类型。通过对祁连成矿带地质、矿产、物探、化探、遥感等资料的综合分析,并结合野外调研和室内的再研究,共圈定69处成矿远景区,其中A类5处,B类23处、C类41处。在此基础上,结合最新的地质找矿成果,优选出铜、金、铅、锌、钨远景区16处,作为今后矿产资源评价首选地区。On the basis of a synthetic analysis of ore-forming conditions and regional mineralization characteristics in the Qilian metallogenic zone, it is proposed that marine volcanic, contact metasomatic （skarn）, meta-sedimentary （including sedimentary exhalative） and ductile shear zone types are the major target ore-deposits in the zone. By means of study on geology and ore deposits as well as geophysical, geochemical exploration and remote sensing, 69 prospecting areas have been located. Among them, 5 areas are grade A, 23 areas grade B and 41 grade C, and 16 copper, lead, zinc, gold and tungsten target areas for mineral resource assessment have been selected.
