摘　　要：本文详细描述了贵州罗甸纳水上石炭统罗苏阶 (L uosuan)和滑石板阶 (Huashibanian)的牙形刺序列 ,自上而下可详细划分为 :Diplognathodus ophenus- D.ellesmerensis,Idiognathoides ouachitensis,Streptognathodus expan-sus,Idiognathoides sulcatus parva,Idiognathodus primulus- N eognathodus bassleri,Idiognathodus primulus-N eognathodus symmetricus,N eognathodus symmetricus,Idiognathoides corrugatus- I.pacificus,I.sinuatus,I.sulcatus sulcatus和 Declinognathodus noduliferus等带。Declinognathodus noduliferus,Idiognathoides ouachitensis和 Mesogondolella clarki的首次出现分别代表罗苏阶、滑石板阶和达拉阶的开始。根据牙形刺和有孔虫的序列 ,罗甸纳水剖面上石炭统的罗苏阶和滑石板阶可与俄罗斯的巴什基尔阶 (Bashkirian)、莫斯科阶 (Moscovian)以及北美的莫罗阶 (Morrowan)和阿托克阶 (Atokan)This paper describes in detail the conodont sequence of the Upper Carboniferous Luosuan and Huashibanian in the Nashui section of Luodian, Guizhou. The following conodont zones can be recognized in the descending order: Diplognathodus ophenus D. ellesmerensis, Idiognathoides ouachitensis, Streptognathodus expansus, Idiognathoides sulcatus parva, Idiognathodus primulus Neognathodus bassleri, Idiognathodus primulus Neognathodus symmetricus, Neognathodus symmetricus, Idiognathoides corrugatus I. pacificus, I. sinuatus, I. sulcatus sulcatus and Declinognathodus noduliferus zones. The first occurrences of Declinognathodus noduliferus, Idiognathoides ouachitensis and Mesogondolella clarki are considered as the markers for the bases of the Luosuan, Huashibanian and Dalaan, respectively. Based on the conodont and fusulinid sequences, the Luosuan and Huashibanian of Luodian, Guizhou can be correlated with the Bashikirian and Moscovian of Russia, and Morrowan and Atokan of USA.
