Major rock salt deposits, also known as halite, are found on all continents and originated from the evaporation of ancient seawater. These deposits occur in extensive beds and as salt domes.12
Key locations include:
- North America: Extensive deposits are mined in the United States (notably New York, Texas, and Louisiana), Canada, and Nova Scotia.132
- Europe: Significant deposits are found in Germany (including the North German Plain), Poland, Hungary, Romania, and near Dax, France.124
- Asia: Deposits occur in the Salt Range of Pakistan, as well as in Iran, India, and the Sichuan province of China.12
- Russia: Large deposits are located in the southeastern region of the country.2
These formations are often associated with sedimentary rocks such as limestone, dolomite, and shale. While some deposits remain unexploited, others are heavily mined for industrial and domestic use.213
