| 摘 要： | 在鄂西、松(滋)宜(都)地区松木坪原下三叠统大冶组底砾岩中,首次发现晚二叠世的旋齿鲨化石和火山碎屑物,从而把该层砾岩划归二叠系顶部,改称“顶砾岩”为好,在本区此层相当于大隆组,而把原长兴组划归吴家坪组上段。

| Abstract: | Abstract The feat that some edestidae fossils (Helicoprion SP. ) and volcanic cinders were
collected from a stratum .which was originally called "the basal conglomerate "of the Trias-
sic system da ye Formation, at Songmuping in Songsi-Yidu area of west Hubei suggests that
this stratum is actually the top of the Permian Epoch and should be renamed as "Top Con-
glomerate",In this area .the concerned stratum is equivalent to the Dalong Formation ,and
the original Changxing Formation should be defined as the upper section of the Wujiaping
Formation. |
