滇西保山西邑地区香山组一段牙形石的发现及其时代意义
The discovery of conodonts from the first Member of the Xiangshan Formation in the Xiyi area, Baoshan, western Yunnan Province, and its biostratigraphic significance
摘要
Abstract
The first Member of Xiangshan Formation in the Xiyi Pb-Zn mining area of Baoshan is rich in conodont,and 5 genera,7 species,1 conformis species and 2 undetermined species were identified.They are:Ancyrodella curvata,A.nodosa,A.spp.,Ancyrognathus triangularis,Icriodus alternatus alternatus,I.sp.,Palmatolepis hassi,Pa.simpla,Polygnathus webbi,Po.cf.tenellus,and Po.sp..The conodonts assemblage is considered to be correlated with Late Palmatolepis rhenana zone,suggesting that the first Member of Xiangshan Formation is Late Frasnian of Late Devonian instead of Early Carboniferous in age.关键词
