According to the classification principles of lithological lineage units, the granitic rocks may be divided (in descendi按岩石谱系单位划分原则,由早到晚划分为中官营子和榆树林子两个超单元,前者由西窑单元、二道沟单元组成,后者由李台子、碾盘山和敖包山单元组成。
Based on the study of geologic characteristics, such as mineralogic assembladge, structural and textural features of gra摘要本文在研究贵东花岗岩岩体岩石矿物组合、结构构造等地质特徵的基础上,运用花岗岩的岩石化学、微量元素和同位素等分析数据,采用目前广泛应用的几种岩石化学图解、微量元素和同位素图解等方法,判别了贵东岩体形成的构造环境爲造山带后碰撞型。
