中文摘要：

Zhangcunping 区域在 Huangling 背斜的北方手足位于 Yichang，湖北省。这里， Ediacaran Doushantuo 形成的沉积继任在 Weng'an 区域与那是类似的，贵州省。很多新微化石(主要 acanthoacritarchs ) 从在这的 Doushantuo 形成，区域在这篇论文被报导。在 Weng'an ，贵州省和在 Yangtze 的 Doushantuo 形成的硅化的生物区系的 Doushantuo 形成的 phosphatized 生物区系塞满的石块集合表演类似，建议 Zhangcunping 区域是为在 Weng'an 区域之间的 Doushantuo 形成的关联的一把钥匙，贵州省和 Yangtze 峡。而且，新锆石虾 U-Pb 年龄(614.0 ± 7 .6 妈) 首先在 Zhangcunping 区域在 Doushantuo 形成的中间在暴露的表面下面从一根地平线被获得。这年龄不仅为 Ediacaran Doushantuo 形成的分提供一本新资料，而且显示在在 Yangtze 站台的 Doushantuo 形成的中间的暴露的表面的年龄应该对 614.0 ± 7 .6 妈后面。由于在暴露的表面上面位于的 Weng'an 生物区系的地平线， Weng'an 生物区系的年龄应该也对 614.0 ± 7 .6 妈后面。

英文摘要：

The Zhangcunping area is located at the north limb of the Huangling anticline in Yichang, Hubei Province. Here, the sedimentary succession of the Ediacaran Doushantuo Formation is similar with that in the Weng＇an area, Guizhou Province. A large number of new microfossils （mainly acanthoacritarchs） from the Doushantuo Formation in this area are reported in this paper. The fossil assemblage shows similarity as the phosphatized biota of the Doushantuo Formation at Weng＇an, Guizhou Province and the silicified biota of the Doushantuo Formation at the Yangtze Gorges, which suggests that the Zhangcunping area is a key for correlation of the Doushantuo Formation between the Weng＇an area, Guizhou Province and the Yangtze Gorges. Besides, a new zircon SHRIMP U-Pb age （614.0＋7.6 Ma） is first obtained from a horizon underneath the exposed surface in the middle of the Doushantuo Formation in the Zhangcunping area. This age not only provides a new datum for subdivision of the Ediacaran Doushantuo Formation, but also indicates that the age of the exposed surface in the middle of the Doushantuo Formation in the Yangtze Platform should be posterior to 614.0±7.6 Ma. Due to the horizon of the Weng＇an biota situated above the exposed surface, the age of the Weng＇an biota should be posterior to 614.0±7.6 Ma as well.
