摘要
通过对吐哈盆地托克逊地区二叠系、三叠系、侏罗系的野外剖面实地观察及大量化石鉴定成果的综合分析，认为该区地层发育不全，侏罗系源岩的区域性盖层齐古组（Ｊ３ｑ）缺失，局部性盖层残缺不全。该地区的主力源岩应以上二叠统和三叠系为主。同时通过对中生代淡水瓣鳃类、脊椎动物的研究。
Through comprehensive analysis of site observation of outcrop section of
Permian, Triassic and Jurassic and fossil analysis in Toksun area, TurpanHami basin, it is
suggested that stratigraphic hiatus occurrs in study area. Qigu formation(J3q) as regional
caprock of Jurassic source rock is missing and local is also incomplete. The major source rock
in study area may be dominated by Upper Permian and Triassic. Moreover, paleoecology and
paleoclimatic variation in Late TriassicJurassic are preliminarily discussed on a basis of study
over freshwater Lamellibranch and vertebrate of Mesozoic.
