【摘要】 报道了采自青藏高原东部玉树隆宝蛇绿混杂岩硅质岩岩块中的放射虫化石。该放射虫组合包括Latentifistula cruxNazarov et Ormiston,Pseudoalbaillella scalprata scalprataHoldsworth et Jones,Pseudoalbaillella scalprata rhombothoracataIshiga,Pseudoalbaillellasakmarensis(Kozur)等。该放射虫组合属于Pseudoalbaillella scalprata rhombothoracata带,该带可以进行全球对比,地质时代为早二叠世。放射虫动物群与可可西里、滇西等地的古特提斯放射虫组合一致,它指示了玉树早二叠世存在深水沉积盆地。更多还原

【Abstract】 This paper reports the Early Permian radiolarians found from the chert of the Longbao ophiolitic mélange in Yushu,east of Qinghai-Tibetan Plateau.This radiolarian assemblage includes Latentifistula crux Nazarov et Ormiston,Pseudoalbaillella scalprata scalprata Holdsworth et Jones,Pseudoalbaillella scalprata rhombothoracata Ishiga,Pseudoalbaillella sakmarensis(Kozur),et al.It is characterized by radiolarians and can be correlated with the Early Permian radiolarian assemblages of Hoh Xil and the West Yunnan of China.This discovery indicates that the Early Permian basin is a wide pelagic basin in the Yushu area.更多还原
