贵东岩体地质地球化学特征及其形成的构造环境识别
Geologic-geochemical characteristics of Guidong granitic massif and recognition of geo-tectonic environment at the time of its emplacement
【摘要】 本文在研究贵东花岗岩岩体岩石矿物组合、结构构造等地质特征的基础上 ,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为造山带后碰撞型
【Abstract】 Based on the study of geologic characteristics,such as mineralogic assembladge,structural and textural features of granite of Guidong granitic massif,and by using petrochemical,trace-element and isotopic data,and some petrochemical,trace-element and isotopic diagrams widely applied to the identification of geo-tectonic environments,authors recognize that Guidong granitic massif was emplaced in post-orogenic collision environment.
