摘要
新疆云雾岭地区花岗岩主量元素特征显示其为高钾钙碱性偏铝质—弱过铝质A型花岗岩,是巴颜喀拉地体抬升阶段早中期(侏罗纪)岩浆作用的产物。构造环境判别为POG型花岗岩,是大陆地壳后造山阶段向板內阶段转换时期的物质反映。
Characteristics of macroelements in granite in Yunwuling area is high - K calc - alkaline metaluminous to weakly peraluminous ＂A Type＂ granite, which was generated by early to metaphase （Jurassic） magmatism among the Baryan Har Terrain ascending. Based on the tectonic setting discrimination, the rock is ＂POG type＂ granite, which was generated by the crust transforming from post orogenesis phase to intraplate phase.
