The pink color of Himalayan salt comes from iron oxide impurities. It is mined from the Salt Range mountains in the southern part of the Pothohar Plateau, south of the Himalayas in Pakistan. Himalayan salt is obtained from a thick layer of Ediacaran to early Cambrian evaporites in the Salt Range Formation. This geological formation includes crystalline halite mixed with potash salts, covered by gypsiferous marl, and interlayered with gypsum and dolomite beds, along with occasional seams of oil shale.
