... Abstract The Isthmian Salt basin occupies the whole northern part of the Isthmus of Tehuantepec. Identified strata range from probable Permian to upper Miocene. Post-Miocene deposits unconformably overlie all other strata, but no study has been made of them. The Miocene section has been studied...
