摘　　要：新疆西天山那拉提构造带变质核部杂岩分布于新疆巩留县那拉提山山脊北侧,整体沿那位提南缘构造带北侧呈近东西向展布,为一套由高级变质表壳岩、灰色片麻岩组成的早前寒武系高级片麻岩系,历经多期不同构造体制变形变质改造与再造,形成多相片麻岩系,并呈长垣状变质核部杂岩隆升,构成那拉提造山带的核部构造物质组成。The complex in the metamorphosed core of the Nalati tectonic zone in the western Tianshan, Sinkiang, occurs in the north side of Nalati mountain ridge in Gonglu County, Sinkiang. Distributed at east-west direction, it consists of a high-grade metamorphosed gneissic Complex and represents a huge boundary faulted zone of sutured plates, showing the characteristics of subducting structure-ophiolite melange features.
