中天山东段古生代淡色花岗岩的发现及其构造意义
The discovery of Paleozoic leucogranite in eastern segment of Chinese Middle Tianshan and its tectonic implications
-
摘要: 在吐鲁番地区底坎尔南的中天山构造带,新发现含电气石和石榴石的淡色花岗岩侵入于富铝泥质片岩系中。SHRIMP U-Pb锆石年代学分析,表明淡色花岗岩的形成不晚于354±16Ma,同时还给出了600~1200Ma的原岩继承锆石年龄。淡色花岗岩的发现及其形成年龄的确定,表明中天山在354Ma前具有与陆缘弧背景相似的构造环境,并在354Ma前完成碰撞过程,为进一步研究古生代天山构造演化提供了新的证据。
