摘要
The Qingchengzi ore concentration area in Eastern Liaoning Province,consisting of the Qingchengzi lead-zinc deposit and the gold-silver deposits in periphery,is an important site for lead,zinc,gold and silver resources in North China.The distribution of the deposits is strictly controlled by the ore formations.The lead-zinc deposits occur mainly in the middle and lower parts of the third member of Dashiqiao formation,Liaohe Group.While the gold-silver deposits are hosted by the upper part of the third member of Dashiqiao formation and lower Gaixian formation.In regard to the mineralizing periods,the lead-zinc deposits were mostly formed in Paleoproterozoic to Mesozoic eras,genetically belonging to sedimentary metamorphic-magmatic hydrothermal reformation type.The forming of the gold-silver deposits was control by Mesozoic magmatism and tectonics.It is concluded that the lead-zinc deposits and the peripheral gold-silver deposit are associated with each other,in a certain genetic correlation.
