Major rock salt deposits, or halite, are found globally in various geologic formations, including bedded deposits and salt domes.1

North America

In the United States and Canada, extensive bedded salt deposits are mined for industrial and domestic use. Significant quantities are located in Texas, Utah, Kansas, Louisiana, Michigan, Ohio, western New York, and Ontario. Additionally, Nova Scotia contains important deposits, and the U.S. Gulf Coast is noted for its abundant salt domes.12

Europe

Europe features widespread salt deposits, particularly in Germany, which hosts extensively mined salt domes in the North German Plain. The sub-Carpathian region, spanning Poland, Hungary, and Romania, contains both bedded deposits and ancient salt domes. Other significant production occurs in France and Russia, where salt is precipitated in ancient lakes like Lake Baskunchak.13

Asia

Asia holds vast reserves of rock salt. Notable deposits include the Salt Range in Pakistan and various formations in Iran. In China, the Sichuan province has been a center for salt well production for over 2,000 years.41
