Introduction on Metallogenic Series of Qilian Metallogenic Province

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.
