祁连造山带早古生代矿床成矿系列与演化

Metallogenic Series and Evolution in Qilian Orogenic Belt in Early Paleozoic

祁连山造山带是中国的一个重要构造成矿带。文章依据成矿构造环境,结合区域主要矿种分布及其成矿类型和成矿时代等特征,应用矿床成矿系列理论,将祁连造山带北祁连早古生代汇聚陆缘铜、铅、锌、钨(钼)、金、蛇蚊石成矿带和南祁连早古生代陆缘裂解带铜、镍(铂族)、铬、金、稀土、黄铁矿成矿带中的矿床划归为6个成矿系列。在成矿系列、亚系列总结论述基础上,探讨了造山带早古生代区域成矿及成矿系列演化规律。

The Qilian orogenic belt is an important tectonic and metallogenic belt in China. According to tectono-metallogenic setting in combination with main mineral distribution and metallogenic types and ore-forming epochs in this orogenic belt, the authors used the theory of metallogenic series to divide the deposits of the North Qilian Early Palaeozoic convergent epicontinental Cu, Pd, Zn, W(Mo),Au, ophiolite metallogenic belt and the South Qilian Early Palaeozoic epicontinental rifting Cu, Ni(Pt), Cr, Au, rare elements and pyrite metallogenic belt into six series. On the basis of summarization of metallogenic series and subseries, the authors have discussed regional metallogeny and evolutionary regularity of metallogenic series in Qilian orogenic belt in Palaeozoic .
