Tract delineationThe Gulf of Mexico tract consists of areas of Jurassic salt diapirs believed to have the potential for potash were outlined within known areas of Jurassic rock occurrence in the southeastern United States and eastern Mexico as determined using Ege (1985, plate 1) and a geologic map of Mexico (University of Arizona Center for Mineral Resources, 1999).
