The Permian Zechstein is a good candidate for solution mining and salt cavern storage, with sizeable halite-dominated salt structures and halite beds at optimal depths below the seabed. The FAB's geological history makes it the optimal site for salt cavern storage in the Central North Sea where much of the Zechstein has been more …

Halite commonly known as rock salt, is the mineral form of sodium chloride (NaCl). Halite forms isometric crystals. The mineral is typically colorless or white, but may also be light blue, dark blue, purple, pink, red, orange, yellow or grey depending on the amount and type of impurities. It commonly occurs with other evaporite deposit minerals ...

The authors interpret these beds as facies formed in salt-pan or hypersaline-lagoon, transitional, and mudflat environments. Halite is distributed approximately as it was deposited. Breccia in limited areas along one halite margin indicates post-burial dissolution, and these breccials are key to identifying areas of subrosion.

V.A Evaporite. Evaporite deposits (largely bedded halite, sylvite, gypsum, anhydrite, and various potash salts) form from the precipitation of solid mineral crystals from a concentrated solution of salt- or freshwater, in other words, from brine.

Under pressure, these deposits flow upwards to form large salt domes that distort the surrounding beds, often forming traps for oil and natural gas. Much of the offshore production of hydrocarbons along the Texas and Louisiana coast is associated with salt domes. In rock shops, large halite crystal masses are often sold as decorative stones.
