Several diapiric and related salt structures are located on the Sabana de Bogota, an elevated rolling upland 2,500 to 3,000 meters above sea-level in the central part of the Cordillera Oriental. The structures, which are exposed in locally exploited salt mines, are composed of salt and interbedded euxinic shales of late Triassic or Jurassic age. The association of the salt deposits with Upper Cretaceous formations necessitates a penetration of more than 13,000 meters of predominantly clastic sediments.

The structures, like those in Rumania, are thought to be the result of horizontal stress. It is believed that they had their inception during very recent geologic time, possibly as late as Pliocene or even Pleistocene.
