Summary:

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

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.
