PBDB Interval

Chadian subage

346.7 - 340.2 Ma

The definition of this interval in the timescale Carboniferous of Western Europe is taken from the following source:

W. B. Harland, R. L. Armstrong, A. V. Cox, L. E. Craig, A. G. Smith and D. G. Smith. 1990. A Geologic Time Scale 1989. view

The top age has been interpolated based on the differences between the ages for international timescale boundaries quoted in the source and the currently accepted ages for those boundaries.

There are intervals in 6 timescales which overlap this one. show
