| 摘 要： | 岩石地球化学特征显示,西天山木札尔特岩群成岩于塔里木原始古陆台内部毗邻陆缘活动带部位.后期木札尔特岩群总体经历3期变质作用和4期变形作用改造:早期低角闪岩相区域动力热流变质作用(M1)与前震旦纪塔里木运动(D1)相对应,构成近EW向断续展布的普通角闪石变质相带；主期角闪岩相区域动力热流变质作用(M2)与奥陶纪末至泥盆纪初的俯冲造山(D2)相对应,宏观上构成近NEE向展布的铁铝榴石-矽线石变质相带；晚期中高绿片岩相区域动力退变质作用(M3)与泥盆纪末至石炭纪末期的同碰撞造山(D3)相对应,宏观上构成叠加于先期变质相带之上的具网结状组构的动力变质带. |

| Abstract: | Geochemical characteristics show that The Muzhaerte Group Complex in western Tianshan Mountains formed in the mobile belt of the Tarim proto-continent margin.Later period the Muzhaerte Group Complex passed through three issue of superimposition deterloration and four issues distorts:earlier period it passed with low-hornblend-phase regional metamorphism(M1) in Tirim Movement in Pre-Sinian Period(D1),which formed the E-W-trending hornbiende metamorphic facies blet;lord period it passed with hornblend-phase r... |
