| 摘 要： | 对东准噶尔北缘造山带内花岗质岩石以岩石地球化学特征为主的对比研究发现，该区主要存在两类花岗质岩石：造山带钙碱性花岗岩类和富碱花岗岩类。部分钙碱性花岗岩与新疆北部的埃迭克质岩具有相似的岩浆亲和性，而富碱花岗岩更多的表现出碱性花岗岩的岩石地球化学特点？两类花岗质岩石分别产于大陆碰撞造山带造山演化的俯冲环境和陆内后碰撞环境，... |

| Abstract: | We have made a comparative study on petro-geochemical characteristics of the granitoid rocks in the northern margin of the East Junggar area.The result shows that two types of granitoids exist in the area,i.e.,orogenic calc-alkali granite and alkali-rich granitoid.There are similar magmatic affinities between some calc-alkali granitoids and adakite in northern Xinjiang,while alkali-rich granite exhibits similar rock geochemistry characteristics of alkali granite.These two types of granites occur in the subd... |
| Keywords: | petro-geochemistry two types of granitic rock tectonic environment post-collision north margin of East Junggar |
