Graptolite Biostratigraphy of Liantan Formation of Lower Silurian of the Dajianshan in Liantan, Yunan County, Guangdong Province
摘要
Abstract
The Lower Sliurian Liantan Fm,consisting of shales,is well developed at Dajianshan,in Liantan,Yunan County,Guangdong Province.Based on detailed research on the graptolite of Liantan Fm,6 genera and 12 species were found in the Dajianshan section.They respectively belong to 3 graptolite zones:① Demirastrites triangulates;② Demirastrites convolutus;③ Monogra ptus sed gwickii.These graptolite assemblages of Liantan Fm in the study area could be correlated with the graptolite assemblages of Longmaxi Fm in Yichang,Hubei Province,Anzigou Fm in the sounth of the West Qinling Mountains,Longmaxi Fm in Ningqiang,Shanxi Province,Shuangchanghe Fm in Chengkou,Sichuan Province,and Angzanggou Fm in the Northern Qilian Mountains and Zhangwan Fm in the east of the Eastern Qinling Mountains.Hence,the age of Liantan Formation in the stuy area should be Aeronian in the Early Sliurian.关键词
