Feng Qinglai Du Yuansheng (China University of Geosciences, Wuhan 430074)Zhang Zongheng Zeng Xianyou (The 3nd Geological Party, Henan Bureau of Geology & Mineral Resources, Xinyang 464000)  
The radiolarian fauna described in this paper was collected from the Caijiawa marble (correlation with the Yianlinggou Fortnation in Qinling Group) in Tongbai region of Henan Provinoe, and includes 8 species (3 uncertain and 2 new species), 7 genera ( 1 new genus) which are Archaeospongopmnum compactum Nakaseko et Ni shimura, Yangia chinensis Feng, Shengia yini (Feng), Cenosphaera sp., Triassocampe? sp., Pactarentinia sp., Triassomitra zhangi n. gen. et sp. and Triassomitra litangensis n. gen. et sp.. It lived in Continental slope environment of subabyss during the early Triassic. According to the marine Triassic strata found here for the first time in Tongbai region,it is thought that Qinling paleo-ocean during the Permian and Early Triassic ran through entire Qinling-Dabie region, was an important passage way between paleo-Tethys and paleo-Pacific, and was finally closed by Indosinian movement .
