| 摘 要： | 孟山岩体位于吉林省东部延边地区,大地构造位置处于延边褶皱系与中朝准地台交界地带。岩体主要由花岗闪长岩及二长花岗岩组成,发育微粒闪长质包体。岩体同位素年龄为326.4Ma(锆石U—Pb),属中海西期。孟山花岗岩为准铝质、钙碱性系列。其岩石学、矿物学和岩石化学显示大陆弧造山花岗岩类的特点。

| Abstract: | Mengshan Pluton is composed of granocliorite and monzogranite. The ,isotope chronology data show that it emplacd in Middle Hercynian(326.4 Ma zircon U-Pb). The petrochemistry of Mengshan granitoid is featured with high silicon, alkali, lower Fe, Mg; with metaluminous, calcic-alkaline trend. The Features of the petrochemistry, petrology and minerology suggest that Mengshan pluton belong to continental are granitoid |
