| 摘 要： | 新疆东天山地区星星峡一带的原星星峡群为一套岩性复杂、变质程度差异很大的变质岩系,在该区进行的1∶50000区调工作中,通过详细的地表调查和地层剖面测量,并参考了相关变质侵入体的同位素年龄后认为,根据岩石组合、变质程度、同位素年龄等地质标志,可将其初步解体为大致形成于晚太古代—古元古代的天湖岩群(Ar3—Pt1T.)和长...

| Abstract: | The original Xingxing Xia group of Xingxing Xia in Xinjiang is a set of metamorphite system of complex lithology and obviously different metamorphic grade.According to Baishidu 1∶50000 regional geological survey and rocl assemblage metamorphic degree and the combination of stromatolite,strata sequences of this region are rearranged.They include TianHu rock suite of Archean-Proterozoic ear,Xingxing Xia rock suite of Changchengian system.At the same time,wa did the regional contrast research on rock assemblage,metamorphite and deformation of every rock suite. |
