| 中文摘要: |
| 北塔山构造混杂岩(带)为阿尔曼泰古生代板内缝合带,该构造混杂岩(带)是由无序基质和外来岩块组成,划分为蛇绿质混杂岩和泥砂质混杂岩2种类型,并分别建立了索尔巴斯陶岩组和柯克阿得尔岩组2个构造岩石单位。综合研究证明,阿尔曼泰小洋盆洋壳形成的时代为早泥盆世—晚泥盆世,与西伯利亚古板块和古准噶尔地块再次拉张有关。 |
| 英文摘要: |
| Tectonic mélange in the northern Tarshan area is an intraplate suture of Paleozoic Armantai plate consisting of disorder matrix and exotic blocks. It is composed of ophiolite mélange and muddy and sandy mélange and divided into Suoerbastao formation and Kekearder formation. Comprehensive study shows that oceanic floor crust of the small Armantai ocean basin was formed in Early Devonian-Late Devonian period and is related to extension of Paleo-Siberia plate and paleo-Jungar block. |
