| Abstract: | Reinvestigation on the original section of the Changyang Formation reveals that the faults in the top of the section do not seriously affect the sequence of the Changyang Formation and there is no mis-recognition problem on the original recognized sequence of the Changyang Formation.The conodont analysis on the two samples from the original section and nearby area reveals that the Changyang Formation yields a typical Lower Carboniferous conodont assemblage characterised with abundant Siphonodella levis,some... |
