Himalayan salt is mined from the Salt Range mountains, the southern edge of a fold-and-thrust belt that underlies the Pothohar Plateau south of the Himalayas in Pakistan. Himalayan salt comes from a thick layer of Ediacaran to early Cambrian evaporites of the Salt Range Formation. This geological formation consists of crystalline halite intercalated with potash salts, overlain by gypsiferous marl and interlayered with beds of gypsum and dolomite with infrequent seams of oil shale that accumulated between 600 and 540 million years ago. These strata and the overlying Cambrian to Eocene sedimentary rocks were thrust southward over younger sedimentary rocks, and eroded to create the Salt Range.
Himalayan salt is a table salt. Analysis of a range of rock salt salt samples showed them to be between 96% and 99% sodium chloride, with trace presence of calcium, iron, zinc, chromium, magnesium, and sulfate, all at varying safe levels below 1%. Salt crystals have an off-white to transparent color, while the trace minerals in some veins of salt give it a pink, reddish, or beet-red color.
