    摘要:

    通过遥感构造综合解析,认为南天山东段榆树沟-铜花山地区为一巨型构造混杂带。该构造带可划分为南部和北部的两带变质褶皱地层系统、中带的构造混杂系统和不同期次的岩浆侵入体。结合同位素定年和岩浆侵入的综合对比与研究,认为该地区先后经历了五期构造运动,分别为:①南北向逆冲推覆,②北西西向左行走滑,⑧北西西向右行走滑,④南北向逆冲推覆,⑤北北西、北东向断裂。

    Abstract:

    The Yushugou-Tonghuashan area is a typical example of complex structure in orogenic belt. There are varieties of geological mass formed in different high-levels and they undergone different metamorphisms. Based on a comprehensive remote sensing structural analysis, the whole district can be subdivided into three structural belts, namely southern and northern metamorphic fold stratigraphic system, central tectonic mixed system and multi-stage intrusives. Isotopic dating of metamorphics and comparative analysis of rock types, tectonic block types and the characteristics of deformation further indicate that this area experienced five tectonic stages: (1) N-S overthrusting; (2) WNW-ESE trending sinistral strike-slipping; (3) WNW-ESE trending dextral strike-slipping; (4)N-S overthrusting; and (5) NNW and NE late-stage faulting.
