摘要
在论述了吐哈盆地晚石炭世、早三叠世、晚二叠世早-中期、晚二叠世晚期-早三叠世、中晚三叠世、早中侏罗世、中晚林罗世和白垩纪-新生代的沉积格局和物源分析的基础上,总结了吐哈盆地的演化特征,认为,从晚石炭世至三叠纪,吐哈盆地和博格达地区由裂谷盆地逐渐演化为坳陷型盆地.早中侏罗世,吐哈盆地与准噶尔盆地一起成为统一的准平原化坳陷型盆地.到了中晚侏罗世,统一的大盆地开始解体,至第三纪和第四纪,吐哈盆地北部才发展成为前陆盆地.
Based on the provenance analysis, this paper discussed the sedimentary framework in Late Carboniferous, Early Permian, early-middle period of Late Permian, late period of Late Permian -Early Triassic, Mid-Late Triassic, Early-Mid Jurassic, Mid-Late Jurassic and Cretaceous-Cenozoic in Turpan-Hami basin. In Late Carboniferous-Triassic, Turpan-Hami basin and Bogda area evolved gradually from rift basin to depression basin. In Early-Middle Jurassic, Turpan-Hami basin and Junggar basin wholly evolved into united peneplain depression basin which then began to break up during Mid-Late Jurassic, and the north of Turpan-Hami basin evolved into foreland basin during Tertiary-Quaternary .
