| 摘 要： | 齐姆根-桑株河地区石炭-二叠系分布广泛,层位齐全,化石丰富.据实测剖面及系统采集的类及腕足、牙形石、孢粉等化石较准确地厘定了石炭-二叠系各地层单元界线和岩石组合特征,自下而上划分出卡拉巴西塔克组、克里塔克组、和什拉甫组、卡拉乌依组、阿孜干组、塔哈奇组和克孜里奇曼组、棋盘组、普司格组、达里约尔组、杜瓦组,其中下石炭统仅分布于莫莫克以西.早二叠世中晚期-晚二叠世早期新藏公路以东普司格组属河流-湖泊-冲积扇相沉积,莫莫克-齐姆根地区棋盘组,达里约尔组以浅海相与河流三角洲相交互沉积及湖泊-河流相沉积为特征,晚二叠世晚期仅于新藏公路以东沉积冲积扇-扇三角洲相的杜瓦组.

| Abstract: | The Carboniferous-Permian strata are widely distributed in Qimugen-Sangzhuhe area, with complete stratigraphic sequence and abundant fossils. The lithologic associations and boundary of various stratigraphic units are defined based on the measured sections and systematically collected fossils such as fusulinida, brachiopoda, conodonts and spore-pollen. The whole sequence is divided into, from bottom up, Kalabaxitak Formation (C1kl), Kelitake Formation (C1k), Hoshilapu Formation (C1h), Kalawuyi Formation (C2k), Azigan Formation (C2a), Tahaqi Formation (C2-P1)t, Keziliqiman Formation (P1k), Qipan Formation (P1q), Pusige Formation (P1-2p), Daliyar Formation (P1-2d) and Duwa Formation (P2dw). The lower Carboniferous strata are only exposed in the area west of Momoke, while the upper Carboniferous-Permian strata exist evenly in the whole area. Pisige Formation of the middle-late Early Permian to early Upper Permian east of Xinjiang-Tibet highway consists of fluvial-lacustrine-alluvial fan sediments. Qipan Formation and Daliyar Formation in Momoke-Qimugen area consists of sediments of shallow marine facies intercalated with river-delta facies and lacustrine-river facies. Duwa Formation in the area east of Xinjiang-Tibet highway consists of alluvial fan-delta sediments. |
