摘　　要：通过近年来在青海省冷湖镇赛什腾地区进行地质矿产调查,对小赛什腾山一带侵入岩进行了系统研究,该套侵入岩对区内铜钼矿种成矿具有较强的控制作用,经岩石学、岩石地球化学等资料分析认为该区侵入岩形成于后碰撞花岗岩时期构造背景之下,是地壳物质发生部分熔融所形成的,其时代为中二叠世。Through the Lenghu town in Qinghai province in recent years the Saishiteng area of geology and mineral resources investigation, the small and even the systemic research on the intrusive rock mountain area, the set of intrusive rocks for copper and molybdenum mineralization has strong control function, the petrology, rock geochemistry data analysis that the intrusive rocks formed in the period after collision granite tectonic background, is the earth＇s crust matter formed by partial melting, in time to Permian.
