摘要

摘要: 在东天山哈尔里克山发育多期岩浆活动，形成了大面积的花岗岩和超基性岩墙。为限定古亚洲洋在该区的闭合时限，同时阐述超基性岩墙形成的构造环境，文章报道了哈密沁城超基性岩墙（角闪石岩）岩相学、岩石地球化学和锆石U-Pb年龄。研究表明，角闪石岩SiO₂含量为39.00%~45.48%、TiO₂（1.60%~3.01%）、Mg^#在50~60之间，轻稀土相对弱富集（（La/Yb）_N= 1.34~2.25）），铕异常不明显（δEu=0.76~1.12），富集大离子亲石元素（Rb、Ba、K、Sr），相对亏损高场强元素（Nb、Zr、Hf）。角闪石岩属于碱性系列岩石，3件角闪石岩样品的LA-MC-ICPMS锆石 U-Pb年龄分别为298.4±1.7 Ma、297.7±1.6 Ma、295.5 ±1.6 Ma。全岩Sr-Nd组成表明，岩石初始⁸⁷Sr/⁸⁶Sr比值为0.7047~0.7051之间，ε_Nd(t)变化范围在−2.63至+1.81之间。结合对区域地质、年代学、元素地球化学以及Sr-Nd同位素等资料的全面分析，认为沁城早二叠世角闪石岩原岩的岩浆可能起源于岩石圈地幔的部分熔融，形成于后碰撞伸展环境下，同时，暗示哈尔里克山地区古亚洲洋在早二叠世之前闭合。

Abstract: Objective During multiple stages of magmatic activity in the Harlik Mountains of the east Tianshan, extensive granitic and mafic dyke swarms were formed. This study aims to constrain the closure time of the Paleo-Asian Ocean in this area and to elucidate the tectonic environment in which ultrabasic dykes were formed. Methods This study reports petrography, geochemistry, and zircon U-Pb ages of a particular type of ultrabasic dyke swarms (amphibolites) in Qincheng, Hami. Results The amphibolites have SiO₂ contents from 39.00% to 45.48%, TiO₂ contents from 1.60% to 3.01%, and Mg^# values from 50 to 60. They are relatively weakly enriched in light rare earth elements (La/Yb)_N = 1.34~2.25) and show no Eu anomalies (δEu = 0.76~1.12). They are enriched in large ion lithophile elements (LILEs: Rb, Ba, K, Sr) and depleted in high field strength elements (HFSEs: Nb, Zr, Hf). The amphibolites belong to the alkaline rock series. LA-MC-ICP-MS zircon U-Pb dating reveals that these three amphibolites crystallized at 298.4±1.7 Ma, 297.7±1.6 Ma, and 295.5±1.6 Ma, respectively. Whole rock Sr-Nd analysis reveals initial ⁸⁷Sr/⁸⁶Sr ratios from 0.7047 to 0.7051 and ε_Nd(t) values from −2.63 to 1.81. Conclusion Based on the comprehensive analysis of regional geology, chronology, geochemistry, and Sr-Nd isotopes, it is suggested that the primitive magma of the early Permian amphibolites in Qincheng may have been created by partial melting of the lithospheric mantle, and these rocks were formed in a post-collisional extensional tectonic setting. It is furthermore implied that the Paleo-Asian Ocean in the Harlik Mountains region closed before the early Permian.
