1Acanthomorph Biostratigraphic Succession of the Ediacaran Doushantuo Formation in the East Yangtze Gorges,South China显示文摘大 acanthomorphic acritarchs 在华南在几个地区在 Ediacaran Doushantuo 形成的燧石被发现了,包括湖北省的东方 Yangtze 峡,贵州省的 Weng'an 区域,并且在其它地方。然而,他们为 biostratigraphic 分和 Ediacaran 继任的关联的潜力被外形控制, taphonomic 偏爱,和分类问题限制。在 Yangtze 峡, Doushantuo 形成通常被细分进四个 lithologic 成员。在 Weng'an 区域,然而, Doushantuo 形成包括就 mid-Doushantuo erosional 表面分开的更低、上面的部分。在在 Zhangcunping 节的 Yangtze 峡, Doushantuo 继任在 Weng'an 类似于那。到目前为止,在 Yangtze 之间的关联塞满并且 Weng'an 区域,并且在其它地方是争论的一个问题。解决争论,我们在 Yangtze 峡区域选择了八节并且全身地取样了 Doushantuo 形成的燧石小瘤,特别地集中于上面的 Doushantuo 形成。我们的数据证实在第二和第三个成员独立出现的二个不同集合,它被一次否定 13C 旅行(EN2 ) 分开。更低的集合被 Tianzhushania 和大 acanthomorphic acritarchs 的一间多样的套房描绘。上面的集合与更低的集合被区分开来,由(1 ) Tianzhushania 的缺席;(2 ) 出现丰富, 100150 m,光滑墙的球形的微化石;(3 ) 包括种类在这个成员从第二个成员和新形式延长的高度多样的 acanthomorphic acritarchs 的出现;(4 ) 原生生物的未命名的新形式的出现;并且(5 ) 管状的微化石 Sinocyclocylicus guizhouensis 的出现。因为统治 Tianzhushania 的集合不是在澳大利亚的现在,看起来仅仅上面的 acanthomorph 集合是在场的,因此,更低的 Doushantuo acanthomorph 集合在澳大利亚失踪。YIN Chongyu LIU Pengju Stanley M.
