| 摘 要： | 双湖托纳木地区处于北羌塘坳陷南部,仅发育上侏罗统索瓦组和雪山组沉积。本文在地层系统详细剖面测制基础上,对索瓦组和雪山组地层剖面进行立典性研究,重点进行了索瓦组和雪山组的层序地层研究,表明羌塘盆地晚侏罗世层序地层的独特性,从层序地层分析的角度证实了侏罗纪北羌塘盆地原型为前陆盆地。

| Abstract: | Late Jurassic sequence stratigraphy in Tuonamu region of Qiangtang basin in northern Qinghai-Tibet Plateau is studied in the paper.Marine facies of China,middle and upper Jurassic formations were well-developed in Qiangtang basin,which is the most ideal studying region at the present.Tuonamu region is placed in the south of Northern Qiangtang basin,where only developed Suowa formation and Xueshan formation,which belong to upper Jurassic.This paper approached the geologic strata section of Suowa and Xueshan formation based on detailed measuring section of stratum system,and priority researched sequence stratigraphy of the Suowa formation and Xueshan formation,the result shows the uniqueness of the sequence stratigraphy of late Jurassic period in Qiangtang basin. |
