| 摘 要： | 本文论述了安徽歙县伏川蛇绿岩带发现的微古植物化石(计有15属19种)和它的时代意义.经统计优势属有:Leiominuscula,Leiofusa,Asperatopsophosphaera,Germinosphaera, Melanocyillum等5属,通过对比和论证,提出了这些化石形成时代为中元古代蓟县纪.结合同位素年龄资料和地质特征的分析研究,推测了伏川蛇绿岩套形成的地质时代在913～963 Ma之间.

| Abstract: | This paper discussied microflora in the ophiolite belt(containing 15genera and 19 species) and its age significance at the Fuchuan village,Shexian County,Anhui province.It is calculated that dominant genera of these microflora have five genera:Leiominuscula,Leiofusa,Asperatopsophosphaera,Germinosphaera,Melanocyillum.Through correlation data and information,the authors suggerst that the age of these microflora is Mesoproterozoic Jixianian.Based on the analysis and study of the geological character and isotope age of opliolitic suite,the authors proposed the opliolitic suite occurred in 913~963 Ma.. |
