Description

Rogers (1972) proposed the name Metropolis Depression for an inferred basin or depocenter that existed during the Silurian Period and Early Devonian Epoch. The Metropolis Depression is essentially the same as the Vincennes Basin of Droste et al. (1975) and later researchers. Although the name Metropolis Depression has priority, Vincennes Basin has been more widely accepted and published; therefore, use of the name Metropolis Depression should be discontinued.
