摘　　要：本文研究了广西扶绥县柳桥地区二叠纪末期的浅水相小有孔虫动物群。该动物群赋存于硅质岩相地层中的灰岩夹层里。动物群丰度和分异度均较高,共发现12属25种。其中包括长兴期的常见分子如Glomospira,No-dosaria,Colaniella等。此有孔虫组合与Colaniella组合大致相当,可以与类Paleofusulina带和Gallowayiella带相对比。A shallow water smaller foraminifera fauna is studied from limestone intercalations of the upper Permian chert from Liuqiao area, Guangxi Zhuang Autonomous Region, China. The fauna is of relatively high diversity and abundance with 12 genera and 25 species (including sp. unidentified), in which some common species of Upper Permian are present such as Glomospira, Nodosaria and Colaniella. This fauna can be generally correlated with Co- laniella assemblage and Fusulinide Zones of Paleofusulina and Gallowayiella.
