本文描述了河南桐柏西北部蔡家凹大理岩岩片中丰富的高肌虫化石Tongbaiella xinjiensis gen.et sp.nov.、Xianzheella henanensis sp.nov.和Mononotella cf.chuanshanensis Huo et Shu及小壳化石Conotheca sp.共4属4种。据此确定含化石地层为寒武系,属浅海沉积环境。该生物群的发现为解决桐柏—大别造山带与秦岭造山带的衔接、北秦岭加里东褶皱带的东延问题提供了可靠证据,并为该造山带区域地层序列的建立奠定了基础。
This paper describes the abundant high-insect imaginary fossils Tongbaiella xinjiensis gen.et sp.nov., Xianzheella henanensis sp. Nov. And Mononotella cf. chuanshanensis Huo et Shu and Conotheca sp. From the Caijiawa marble in northwestern Tongbai, Henan Province. A total of 4 genera and 4 species. Based on this, it is determined that the fossil-bearing formations are Cambrian and belong to the shallow sea sedimentary environment. The discovery of the biota provided reliable evidences for solving the East Convergence problem of the Caledonian Fold Belt in the North Qinling and linking the Tongbai-Dabie orogenic belt with the Qinling orogenic belt and laid the foundation for the establishment of the sequence of the stratigraphic orogenic belt in the orogenic belt.
