| 摘 要： | 利用野外地质剖面、关键钻井剖面和区域地质资料,在地层划分对比和构造格局研究基础上,系统分析了东北地区中二叠世的构造岩相古地理面貌,将中二叠世作为一个单元进行岩相古地理编图,恢复了东北地区中二叠世的岩相古地理特征。研究表明,中二叠世东北地区主要发育深海-半深海沉积体系、浅海陆棚沉积体系、台地沉积体系、障壁海岸沉积体系以及扇三角洲沉积体系。早二叠世空谷期漠河古陆、佳木斯古陆和华北北缘高地在中二叠世依旧存在,研究区呈主体浅海-半深海沉积,周边古陆的格局。

| Abstract: | Based on the study of stratigraphic division, correlation and structural pattern, field data of the measure ment strata sections, privotal drilling profile and the existing regional geological data were used to make sedimentary facies analysis. The Early Permian tectonic lithofacies paleogeography in northeast China was analysed systematically and the lithofacies paleogeographic map of Middle Permian was produced. The study shows that the sedimentary sys- tems include deep-bathyal depositional systems, neritic shelf sedimentary system, platform sedimentary system and barrier coast sedimentary system and fan delta sedimentary system in Northeast China during the Middle Permian; in Middle Permian,the old lands of Mohe,Jiamusi and the highlands of northern margin of north China of Kungurian in Early Permian still existed and the main depositional area is shallow bathyal deposition surrounded by ancient land. |
