| 摘 要： | 安徽沿长江地区．下奥陶统红花园组发育良好．产大化石Ｃａｌａｔｈｉｕｍ－Ｍａｎｃｈｕｒｏｃｅｒａｓ－Ｃｏｒｅａｎｏｃｅｒａｓ组合及牙形石Ｓｅｒｒａｔｏｇｎａｔｈｕｓ带等。其时代相当皖南下奥陶世宁国阶早期Ｎ１至Ｎ２笔石带；其生物地层特征与扬子地层区基本一致。据此．本文揭示宁国阶早期扬子海与华北海可能是相通的。

| Abstract: | This paper deals with the Honghuayuan Formation in the Yanstze area whose time is equivalent to the N1described herein show that the big fossil association of Calathium-Manchuroceras-Coreaoceras,Serratogwhuszone and deposition are basically consistent with those in the Yangtze stra It.It is suggested that the Yangtze sea was probably connected with the Norm China sea in the early Ningguo stage. |
