| 摘 要： | 齐姆根-桑株河地区侏罗纪形成昔力必里-库斯拉甫断陷盆地和达木斯-莫莫克-克里阳坳陷盆地,其间以琼阔若勒克背斜带相分割.下侏罗统莎里塔什组为冲积扇相沉积,康苏组属湖泊-三角洲相沉积,中侏罗统杨叶组至塔尔尕组以湖泊相沉积为主,上侏罗统库孜贡苏组为扇三角相沉积.沉积特征为侏罗纪早期快速充填,中期稳定沉降,晚期萎缩充填.康苏组、杨叶组湖泊相暗色碳质泥岩、粉砂质泥岩有机质含量高,厚度较大,为塔西南重要的生油岩.

| Abstract: | The Jurassic rocks in Qimugen-Sangzhuhe comprise Xilibili-Kuslapu fault basin and Damusi-Momoli- Keliyang depression basin separated by Qongkuoruolek anticline. The lower Jurassic Shalitash Formation consists of sediments of alluvial fan facies, and Kangsu Formation of sediments of lacustrine-delta facies. The middle Jurassic Yangye Formation and Taergar Formation are mainly composed of lacustrine sediments. The upper Jurassic Kuzigongsu Formation consists of sediments of fan-delta facies. The sedimentation is shown as rapid filling at the early Jurassic, stable subsidence at the middle Jurassic and shrinkage at the upper Jurassic. Kangsu Formation and Yangye Formation contains lacustrine dark carbonaceous mudstone and sility mudstone with high content of organic material and great thickness. These rocks are the important source rocks. |
