青海省三叠系十分发育,分布广泛,含菊石层位较多,材料丰富、完好,是我国研究三叠系及其菊石群的重要地区之一。本文讨论的材料,大多系青海省地质局的同志们在区域地质调查工作过程中采得的, 并交与笔者鉴定、研究。借此特表谢意。这些材料由于产地比较零星,材料不够系统,因此这里暂不建立菊石带,以“层”示之。 Triassic in Qinghai Province is well developed and widely distributed, with more ammonite layers, abundant materials, intact, is one of the important areas of Triassic and its ammonite group in China. The materials discussed in this article are mostly collected by the comrades of the Bureau of Qinghai Province’s geology during the course of the regional geological survey and submitted to the author for identification and research. To thank you very much. These materials due to relatively sporadic origin, the material is not systematic, so here is not the establishment of an ammonite zone, to “layer” show.
