    Lower and Upper Boundaries of Fortunian from Yichang, Hubei, China

    • 摘要: 对湖北宜昌地区滚子坳剖面寒武系纽芬兰统幸运阶顶底界线的位置进行较为细致的研究.通过切片法及酸蚀法对61个样品进行系统处理,获得了大量的小壳化石、疑源类化石及其他分类位置未定化石.系统鉴定和描述了23属44种.根据具刺疑源类化石Asteridium和小壳化石Protohertzina sp.的首现位置以及无机碳同位素BACE曲线最大负值位置可以推断出埃迪卡拉系-寒武系界线应该位于第1层底部往上约10.5 m处;根据Zhijinites longistriatus的首现位置以及无机碳同位素ZHUCE曲线最大值位置可以推断出幸运阶与第二阶的界线位置大致为第4层底部往上约2.78 m.此外,还将峡东地区的小壳化石Ⅱ带和Ⅲ带重新定义,即将Purella antiqua组合(Zone Ⅱ)修订为Purella antiqua-Siphogonuchites triangularis组合;将Aldanella yanjiahensis组合(Zone Ⅲ)修订为Aldanella yanjiahensis-Zhijiniteslongistriatus组合.
