西藏南部泽当西金鲁村附近发现的一套硅质岩含有两个放射虫化石组合 :Capnuchosphaera triassica组合和Pseudostylosphaera nazarovi组合。这些放射虫化石可以同中三叠世拉丁期至晚三叠世卡尼期放射虫动物群对比。这套硅质岩为一外来岩体 ,包括在由高劈理化泥岩组成的混杂岩基质中。这是雅鲁藏布江缝合带三叠纪放射虫的首次报道。
A group of cherts found near Zendangsilulu village in southern Tibet contains two radiolariod assemblages: the Capnuchosphaera triassica assemblage and the Pseudostylosphaera nazarovi assemblage. These radioactive fossils can be compared with the Middle Triassic Latinian and Late Triassic Carney Period larvae. This set of silicalites is an extraneous rock mass that is included in a matrix of melange consisting of highly cleaved mudstones. This is the first report of Triassic radioactive insects on the Brahmaputra suture.
