    吐哈盆地南缘彩霞山东石英闪长岩岩株锆石SHRIMP U-Pb测年

    Zircon SHRIMP U-Pb dating of the east Caixiashan quartz diorite stock, south margin of the Tulufan-Hami basin, East Tianshan, Xinjiang, China

    • 摘要: 彩霞山东石英闪长岩岩株的锆石SHRIMPU-Pb年龄为267.8Ma±1.6Ma,结合克孜尔塔格岩体的同位素年龄综合分析,此年龄值介于王瑜等所研究剪切作用控制的克孜尔塔格岩体右行剪切年龄276~254Ma之间,表明该石英闪长岩岩株的侵位年龄比克孜尔塔格复式岩体晚,为中二叠世早期。
