摘　　要：通过对西天山二叠纪陆相火山岩及成矿作用的研究,指出铜银矿床与长英质火山岩—石英钠长斑岩有直接关系,并从成矿构造背景、产出地质环境、矿床地质特征等方面总结出二叠纪陆相长英质火山岩铜银矿床矿床模式。By research of volcanic rock and mineralization,authous consider that the Cu,Ag deposits were related to felsic volcanic rock, quartz albitophyre immediately. The mineral deposit models of Cu, Ag in felsic volcanic rock of Permian continental facies have been summarized in times of ore-forming structural setting, ore-hosted environment,geological characteristics of the deposits and so on.
