Geochemical characteristic, SHRIMP zircon U-Pb dating and tectonic implication for granitoids in Chonghuer basin, Altai, Xinjiang

  • 通过对新疆阿尔泰冲乎尔地区北缘花岗质类岩石的矿物学、岩石学及电子探针分析研究,鉴定冲乎尔盆地北缘花岗岩属斜长花岗岩.英云闪长岩系列。岩石主微量元素分析显示,花岗岩和盆地火山沉积岩具有相似的微量及稀土元素特征,表现为:准铝到弱铝过饱和的钙碱性系列,镁含量较高,Ba、Y、Nb等大离子亲石元素亏损,轻稀土富集,稀土元素分布曲线为Eu弱负异常的右倾平坦型,岩石地球化学特征显示花岗岩的物质来源可能主要来自中上地壳。用单颗粒锆石SHRIMP U-Pb定年方法。测得该岩体成岩年龄为413±3.8Ma,晚于盆地火山岩436±4Ma,结合花岗岩分布及基底构造特征,认为该期花岗岩受区域南北向构造控制,冲乎尔盆地可能为早古生代火山沉积盆地,盆地岩浆岩相似的元素地球化学特征暗示它们可能具有同源岩浆演化系列的性质。该期花岗岩可能为志留纪活动大陆边缘环境下,古亚洲洋板块向西伯利亚板块俯冲,热一构造作用引起中上地壳部分熔融,在阿尔泰山及其南缘形成S型花岗岩。
