贵州剑河八郎寒武系“清虚洞组”的Redlichia及其地层意义
|
摘要
贵州境内寒武系黔东统都匀阶清虚洞组富含具有重要地层意义的三叶虫莱得利基虫,前人据此将该组由下而上划分为2个三叶虫带:Redlichia(Pteroredlichia)murakamii-Hoffetella-Eoptychoparia组合带和Redlichia(Redlichia)guizhouensis-Redlichia(Redlichia)nobilis富集带。对黔东剑河八郎地区松山剖面非典型的"清虚洞组"中大量的莱得利基虫化石进行了初步研究,根据分类和属种延限,识别出Redlichia(Pteroredlichia)murakamii带和其上的Redlichia(Redlichia)guizhouensis-Redlichia(Redlichia)nobilis组合带。Redlichia(Pteroredlichia)murakamii带的底界可下延至下伏地层杷榔组中上部,但带内未发现常见于黔北地区典型清虚洞组的Hoffetella。剑河八朗松山剖面"清虚洞组"上述两个莱得利基虫化石带可以分别与此前建立的两个掘头虫三叶虫带Arthricocephalus chauveaui带和Protoryctocephalus arcticus带对应,进而为斜坡相区的"清虚洞组"与浅水台地相区同期地层的生物地层对比提供化石依据。
Two redlichiid trilobite zones, the Redlichia(Petroredlichia) murakamii-Hoffetella-Eoptychoparia Assemblage Zone and the upper Redlichia(Redlichia) guizhouensis-Redlichia(Redlichia) nobilis Abundance Zone, have been recognized in the Cambrian Tsinghsutung Formation(Qiandongian Series, Duyunian Stage) in North Guizhou(platform facies), South China. However, little is known about the redlichiid assemblage of its contemporaneous sediments in the foreslope facies. Here we present new redlichiid trilobite fossils from the "Tsinghsutung Formation" at the Songshan section in Jianhe County, eastern Guizhou(outer shelf facies). So far we have found 3 species of the genus Redlichia, and most of the species are common in the Tsinghsutung Formation of North Guizhou. Based on their occurrences, two zones were detected, in ascending order they are Redlichia(Pteroredlichia) murakamii Zone and Redlichia(Redlichia) guizhouensis-Redlichia(Redlichia) nobilis Assemblage Zone, which positively coincide with two known Oryctocephalid trilobite zones of the Songshan section, Arthricocephalus chauveaui Zone and Protoryctocephalus arcticus Zone, respectively. It is worth mentioning that the Redlichia(Pteroredlichia) murakamii Zone here could begin from the middle part of the underlying Balang Formation, whilst Hoffetella, a typical trilobite taxon in the Tsinghsutung Formation of North Guizhou, is not yet available in Songshan section. New redlichiid trilobite fossils from the "Tsinghsutung Formation" at Jianhe, eastern Guizhou shed new light on biostratigraphy of Cambrian Stage 4 between the Yangtze carbonate platform and deep-water outer shelf facies in South China.
