摘要
本文首次报道了铜仁一带中寒武世“粘土页岩层”(非正式岩石地层单位)中Nangaops、Oryctocephalus、Mufushania,PAGETIA等常见于台江—丹寨小区凯里组三叶虫组合,并将其与凯里组进行了对比,从而正确划分了“粘土页岩层”,为台江—丹寨小区凯里组三叶虫组合在铜仁一带的分布提供了有力的佐证。
The association of trilobite: Nangaops, Oryctocephalus, Mufushania, Pagetia, etc. in 'Clay Shale Layer' (informal lithostra-tigraphic unit) of Middle Cambrian age in Tongren region is first reported. The association is often fonnd in Kaili Formation in the region of Taijiang-Danzhai. So, the discovery of the association furnishes fresh evidence for correct division of the ' Clay Shale Layer' and the distribution of the association of trilobite in Kaili Formation in Tongren Region.
