In the UK, it is known as rock salt. The rock salt (the dried remains of ancient seas) is an underground deposit of salt that is mined and used to grit icy roads and pavements.
Rock salt has formed at various times in the geological past as a result of the drying up of the sea. At these times, the evaporating water left behind beds of sea-salt. Thick deposits resulted from the repeared inundations of the sea, followed by evaporation. This mineral is called halite.Also rock salt can be extracted from ancient rock deposits, known as "Himalayan" or "pink Himalayan" rock salt. It is very high in minerals including iron oxide, which gives it its color. The true Himalayan is mined in Pakistan, but salt from other sources is similarly marketed.
