| 摘 要： | 在测制甘肃文县地区石坊群地层剖面中发现了孢子化石,共计14个属,56个种,将其与贵州独山、都匀地区的早、中泥盆世孢子化石组合对比,发现组合特征基本一致。因而确定了石坊群地层时代属早、中泥盆世,为石坊群地层划分、时代确定及地质构造发展史研究提供了可靠的依据。

| Abstract: | Spore fossils including 14 genera and 56 species were discovered in the Shifang Group of Wenxian Coun-ty, Gansu Province. The discovery indicates that Shifang Group in this area belongs to early-middle Devonian be-cause these spore fossils can be compared with spore fossils of the Dushan and Duyun areas in Guizhou Province.This wonderful discovery has an important geologic significance in the division and time determination of the stra-tum and tectonic evolution study in this area. |
