| Abstract |
Recent work indicates that a new biostratigraphic criterion and a new stratotype are required to define the Tournaisian-Visean (T-V) boundary. Investigation of the T-V transition in Guangxi (South China) has provided data which give a new insight on the problem. The foraminifer Eoparastaffella provides a goon new criterion for the establishment of the T-V boundary, based on its evolutionary stages. The sequence stratigraphy of this interval may also play a part in the recognition of the boundary. The idea of a type basin rather than a type section is put forward in preference to a single section as a better way of understanding the transition. |
