祁连成矿省成矿系列概论

Introduction on Metallogenic Series of Qilian Metallogenic Province

借鉴已有的中国矿床成矿系列和亚系列,在祁连成矿省划分的4个Ⅲ级成矿带基础上,对该成矿省内的成矿系列进行了深化研究,相对于含矿或成矿建造将成矿系列划分为同生、准同生和后生等类别。在祁连成矿省初步确定出24个成矿系列族,并进一步划分为47个成矿系列。加里东期是该区重要的成矿期,且主要形成与中基性火山岩同生的Fe-Cu-Pb-Zn-Au成矿系列。

According to the metallogenic series and sub-series of China,the metallogenic series of the Qilian metallogenic province are further researched based on the four Ⅲ-degree metallogenic belts.Based on the host rock formation and ore-forming process,the metallogenic series are divided into the syngenetic,para syngenetic and epigenetic series.In this study,the main mineral deposits of Qilian metallogenic province fall into 24 series families and 47 series.It is showed that the Fe-Cu-Pb-Zn-Au syngenetic series with the intermediate and mafic volcanic rocks in the period of Caledonian are the main mineralization stage.
