摘要: 新疆三塘湖盆地中二叠统芦草沟组动物群以半咸水类型古鳕类和介形类Tomiella-Kelameilia-Panxiania组合为主体,纵向上与海相化石交替出现,反映了典型的陆缘近海湖泊环境。古植物和孢粉化石组合反映了安加拉植物群面貌,代表温湿气候背景。陆缘近海湖泊环境使水生生物群呈现多样性发展并异常繁盛,为芦草沟组优质生油岩的形成提供了生态环境保证。

Abstract: The fauna of Lucaogou formation of Middle Permian in Santanghu basin is dominated by Tomiella?Kelameilia?Panxiania combination of brackish palaeoniscoid and ostracoda, which occur alternatively with the marine fossils vertically, reflecting a typical epicontinental lake environment of paralic facies. The fossil plants and sporopollen assemblage reflect the features of Angara flora, representing the warm?humid climate background. The epicontinental lake environment of paralic facies enabled the diversified development and unusual flourishing of aquatic biota, thus providing material foundation for formation of premium oil source rocks of the Lucaogou formation
