| 摘 要： | 本文研究的苏皖地区二叠纪孤峰和大隆组放射虫硅质岩中的有孔虫属国内首次报道，通过这两个硅质岩相区有孔虫组合特征的分析，它们可与同时代碳酸盐岩相区的有孔虫组合进行比较，根据生物组合与地球化学特征分析，这两个组的含有孔虫的放射虫硅质岩可能是由于上升流作用形成的沉积。

| Abstract: | Some foraminifers in the radiolarites of Gufeng and Dalong Formation (Permian) in Jiangsu and Anhui Provinces are reported for the first time. Based on the analysis of the foraminiferal assemblages in these siliceous facies tracts, they are compared with foraminiferal assemblages in the carbonate facies tracts of the same age. Judging from the features of faunal assemblages and geochemistry, the radiolarites containing foraminifers in these two Formations might be formed by the effect of the upwelling. |
