| 摘 要： | 国际地层委员会确认二叠系下界以牙形刺 Streptognathodus isolatus的首次出现为标志。目前在我国 ,S.isolatus仅见于贵州紫云羊场一地 ,产出层位介于 Streptognathodus elegantulus带与 S.elongatus- S.simplex带之间的界面 ,且大体与类 Pseudoschwagerina uddeni- Ps.texana带之底相当。本文推荐贵州紫云羊场剖面作为我国的石炭系与二叠系界线层型。

| Abstract: | The basal boundary of the Permian System has been officially ratified by the ICS, with the GSSP at Aidaralash Creek, northern Kazakhstan. It is defined on the first occurrence of the conodont Streptognathodus isolatus Chernykh et al . 1997 slightly below the contract between the ammonoid genozones of Shumardites Vidrioceras below and Svetlanoceras Juresanites above, corresponding approximately to the base of the fusulinacean Sphaeroschwagerina vulgaris S.fusiformis Zone. In China, the Streptognathodus isolatus only has been defined in Carboniferous Permian boundary section of Yangchang, Ziyan of Guizhou Province, and is referred to as the Streptognathodus elongatus S.simplex Zone. The Yangchang section is suitable as a stratotype for Chinese Carboniferous Permian boundary. |
