摘　　要：岩石学、地球化学和同位素地质年代学研究表明，中天山构造带北缘胜利达坂地区的花岗岩类至少是两期岩浆活动的产物，胜利达坂岩体形成于加里东晚期（４３９Ｍａ）的岛孤构造环境，红色钾长花岗岩形成于华力西晚期，属造山期后花岗岩．etrological, geochemical and isotopic geochronological study demonstrate that granitoids occured in Shenglidaban area on the northern margin of the central Tianshan mountain tectonic belt are produets of two periods of magmatic activity. The Shenglidaban rock body was formed in late Caledonian (439 Ma) and in island arc tectonic environment. The red moyite was formed in late Variscan and belongs to postorogenic granitoid.
