摘　　要：依据成矿地质构造背景、含矿岩石建造、成矿时代和主要矿种 ,结合重砂和化探异常的分布特征 ,初步将祁连 级成矿带划分为北祁连、中南祁连 2个 级成矿带 ,2 1个 级成矿带 ,简要论述了祁连成矿带金属矿床地质成矿特征和时空分布规律 ,明确了该区的主攻矿种为铜、铅、锌、金、钨等及其主攻矿床类型 ,分析了找矿潜力 。The Qilian metallogenic belt is one of the most important Second level metallogenic belts in China By means of the research on the geological tectonic settings, the ore rock formations, the minerogenetic epoch and the main ore types of the Qilian metellogenic belt, and combined with the results of the geochemical exploration and panning anomalies, the Qilian Ⅱ level metallogenic belt would been subdivided into two Ⅲ level belts and twenty one Ⅳ level belts in this paper The metal metallogenic characteristics and the distribution regularity of the mineral deposits of each of the Ⅳ level metallogenic belts have been discussed respectively Based on the synthetical analysis, the Cu, Pb, Zn, Au and W ore deposits are the main exploration targets in future, and the focal area of the next stage ore finding work have also been proposed
