| Abstract: | The base of the Middle Ordovician(i.e.Dapingian Stage) has been defined at the first appearance datum(FAD) of conodont Baltoniodusl triangularis at Huanghuachang,Yichang,China, but the precise correlation of the boundary to regions of other facies remain to be resolved.Herein we review the biostratigraphy and chemostratigraphy of the Huanghuachang Global Standard Stratotype-Section and Point(GSSP) section,and present our latest stratigraphic work on the nearby Chenjiahe section in Yichang,and the Hengtang Q... |
