摘要
本文详细描述了贵州罗甸纳水上石炭统 (宾夕法尼亚亚系 )剖面的生物地层和年代地层 ,其牙形刺序列自上而下可详细划分为 :Streptognathodus isolatus,S. wabaunsensis,S. tenuialveus,S. firmus,Idiognathodusnashuiensis,Streptognathodus simulator,S.guizhouensis,S.gracilis- S.excelsus,S.cancellosus,S.clavatulus,S. nodocarinatus,Idiognathodus podolskensis,Mesogondolella clarki - Idiognathodus robustus,Diplognathodusophanus- D.ellesmerensis,Idiognathoides ouachitensis,Streptognathodus expansus,Idiognathoides sulcatus parva,Idiognathodus primulus- N eognathodus bassleri,Idiognathodus primulus- N eognathodus symmetricus,N eognatho-dus symmetricus,Idiognathoides corrugatus- I. pacificus,I. sinuatus,I. sulcatus sulcatus,Declinognathodusnoduliferus和 Gnathodus bilineatus bollandensis等带。Declinognathodus noduliferus和 Streptognathodus isolatus的首次出现分别代表上石炭统 (宾夕法尼亚亚系 )和二叠系的开始。根据牙形刺和有孔虫的序列 ,罗甸纳水剖面的上石炭统 (宾夕法尼亚亚系 )地层自下而上可划分为罗苏阶 (L uosuan)、滑石板阶 (Huashibanian)、?
This paper describes in detail the Upper Carboniferous (Pennsylvanian) biostratigraphic and chronostratigraphic strata from the Nashui section, Luodian of Guizhou.They can be subdivided,in the descending order, into: the Streptognathodus isolatus, S. wabaunsensis, S. tenui- alveus, S. firmus, Idiognathodus nashuiensis, Streptognathodus simulator, S. guizhouensis, S. gracilis-S. excelsus, S. cancellosus, S. clavatulus, S. nodocarinatus, Idiognathodus podolskensis, Mesogondolella clarki-Idiognathodus robustus, Diplognathodus ophanus-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 , Declinognathodus noduliferus and Gnathodus bilineatus bollandensis zones. The first occurrences of Streptognathodus isolatus and Declinognathodus noduliferus represents the bases of Permian and Upper Carboniferous, respectively. Based on the fusulinid and conodont zones, the Upper Carboni- ferous strata in the Nashui section can be subdivi- ded , in the descending order, into the Maping, Dalaan, Huashiban and Luosuan stages. Accor- ding to the conodont zones the Upper Carboniferous strata from Nashui can be corralated with the Gzhelian, Kasimovian, Moscovian and Bashkirian in Russian, and the Virgilian, Missourian, Desmoinesian, Atokan and Morrowan in North America.
