Salt is found in the Earth's crust as the mineral halite (rock salt), and a tiny amount exists as suspended sea salt particles in the atmosphere. [36] These particles are the dominant cloud condensation nuclei far out at sea, which allow the formation of clouds in otherwise non-polluted air. [37]
Salt domes are vertical diapirs or pipe-like masses of salt that have been essentially "squeezed up" from underlying salt beds by mobilization due to the weight of the overlying rock. Salt domes contain anhydrite , gypsum , and native sulfur , in addition to halite and sylvite .
Typically made by mining underground salt deposits, this type of salt is processed and refined to remove minerals and impurities, then fortified with anti-caking agents (such as silicon dioxide ...

[15] [16] Table salt is more processed than sea salt to eliminate minerals and usually contains an additive such as silicon dioxide to prevent clumping. [15] Iodine, an element essential for human health, [17] is present only in small amounts in sea salt. [18] Iodised salt is table salt mixed with a minute amount of various salts of the element ...
