摘要:

大兴安岭地区古生界构造变形表明,上古生界自二叠纪末以来遭受了3期构造变形改造:第一期变形为二叠纪末华北板块与佳蒙地块碰撞造成的近EW向展布的断裂和褶皱构造,强度由南向北有减弱的趋势;第二期变形为侏罗纪西太平洋板块俯冲导致的NE—NNE向左行走滑断裂和褶皱构造;第三期为NW向具有右行走滑特征的断裂构造,时间大致在晚侏罗世—早白垩世。综合区域构造、沉积岩古地理分析对比,初步将大兴安岭地区上古生界划分为早古生代、D—C1、C2—P2、P3—T1  4个构造层:早古生代末加里东运动之后,在D—C1期间早期以伸展为主,总体表现为北海南陆的古地理特征;早石炭世末期松嫩地块与额尔古纳—兴安地块沿嫩江—扎兰屯一线碰撞拼接;C2—P2期间总体表现为造山后伸展特征,表现为北陆南海;P3—T1时期古亚洲洋的闭合,海水退出,转为陆相。

Abstract:

The structure and deformation studies show that the Upper Paleozoic have been suffered three deformation events since the end of the Permian in the Daxing’anling area. The first deformation produced E-W trending faults and folds, which were resulted from the collision between the North China plate and Jia-Meng block along the Xar Moron River suture zone. The second deformation formed NE-NNE trending sinistral strike-slip faults and folds due to the western Pacific Oceanic plate subduction to the Asian continent in Jurassic. The third deformation produced the NW trending faults with dextral strike-slip feature in the Late Jurassic-Early Cretaceous. The four tectonic layers of Early Paleozoic, Devonian-Early Carboniferous, Late Carboniferous-Middle Permian and the Late Permian-Early Triassic have been divided according to the studies and the comparisons of regional tectonics and paleo-geography in the Daxing’ anling area. After Caledonian movement in the end of the Early Paleozoic, the area was in the regional extension tectonic setting during Devonian-Early Carboniferous, which developed marine facies sediments to the north and terrestrial facies sediments to the south. In the end of the Early Carboniferous the Songnen block collided with the Ergun-Xing’an block along the Nenjiang-Zhalantun belt. During the Late Carboniferous-Middle Permian, the area was in the regional post-orogeny extension tectonic setting with the sediments of the terrestrial facies in the north and the marine facies in the south. The Paleo-Asian Ocean was closed during the Late Permian-Early Triassic period, the sea water retreated from the area and became terrestrial setting.

Key words: structural deformation, tectonic layer, structural analysis, Upper Paleozoic, Daxing’anling, NE China
