摘要
天全龙门下泥盆统按岩性特征被分为平驿铺组和甘溪组，从甘溪组中识别出两个腕足化石带：Ｄｉｃｏｅｌｏｓｔｒｏｐｈｉａｐｕｎｃｔａｔａ延限带和Ｅｕｒｙｓｐｉｒｉｆｅｒ－Ｒｏｓｔｒｏｓｐｉｒｉｆｅｒ组合带。文章还将其与北川甘溪下泥盆统进行了对比。
The Lower Devonian is divided into the Pingyipu Formation and Ganxi Formation inLongmen of Tianquan County according to the lithological features. Two brachiopod biozones, Dicoelostrophia punctata range-zone and Euryspirifer-Rostrospirifer assemblage-zone are recognizedfrom the Ganxi Formation.A correlation of the Lower Devonian between Tianquan and Ganxi ismade.
