Deposit type

  • Evaporite

Summary:

The deposit is in the Taquari-Vassouras sub-basin and is a bedded evaporite.

The Taquari-Vassouras mine is located near Aracaju (Sergipe state) in north-east part of Brazil. The stratigraphic column of the Taquari-Vassouras sub-basin consists, from the base up to the top, of sediments of age varying from the lower Cretaceous (Aptian) to the Terciary, that overlie discordantly the crystalline basement. The potash deposit is found at a depth of 450–500 m in the Ibura Evaporites which consist, from the bottom up, of limestones, anhydrites, halites, carnalites, tachydrites, with interspersed shales, halites with seams of silvinite, calcilutites (clayey fine-grain limestones) and shales. There are two main potash zones, the Upper Basal Silvinite and the Lower Basal Silvinite.
