| Abstract: | Honghuayuan Formation (lower Ordovicion) in northern Guizhou belongs to the realm of lithostric unit. This paper discusses the meaning of Honghuayuan Formation. According to research of conodont biostratigraphy, the diachronism of Honghuayuan Formation has been verified,its boundary of bottom progressively falls and the boundary of top progressively rises from west to east. For this reason,Honghayuan Formation of norther Guizhou is trapezoid in shape and lies between Tongzi Formation and Mean Formation (or Daban Formation). Finally, according to the evolution of the sedimentary environment, the author preliminary explain the diachronous mechanism of Honghayuan Formation. |
