【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.更多还原
