| Abstract: | 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. |
