In these cases, halite is said to be behaving like a rheid. Unusual, purple, fibrous vein-filling halite is found in France and a few other localities. Halite crystals termed hopper crystals appear to be "skeletons" of the typical cubes, with the edges present and stairstep depressions on, or rather in, each crystal face. In a rapidly ...
Two commercially important halide minerals are halite and fluorite. The former is a major source of sodium chloride, in parallel with sodium chloride extracted from sea water or brine wells. Fluorite is a major source of hydrogen fluoride , complementing the supply obtained as a byproduct of the production of fertilizer.
Hydrohalite is a mineral that occurs in saturated halite brines at cold temperatures (below 0.1 °C). It was first described in 1847 in Dürrnberg, Austria. It exists in cold weather. Phase diagram of water–NaCl mixture

Halite is the mineral form of sodium chloride. Structure. Most alkali metal halides crystallize with the face-centered cubic lattices. In this structure both the ...
The Prairie Evaporite Formation, also known as the Prairie Formation, is a geologic formation of Middle Devonian age that consists primarily of halite (rock salt) and other evaporite minerals. It is present beneath the plains of northern and eastern Alberta , southern Saskatchewan and southwestern Manitoba in Canada , [ 3 ] and it extends into ...
Many salts are halides; the hal-syllable in halide and halite reflects this correlation. All Group 1 metals form halides that are white solids at room temperature. [2] A halide ion is a halogen atom bearing a negative charge. The common halide anions are fluoride (F −), chloride (Cl −), bromide (Br −), and iodide (I −).
Sylvinite is a sedimentary rock made of a mechanical mixture of the minerals sylvite (KCl, or potassium chloride) and halite (NaCl, or sodium chloride). [ 1 ] [ 2 ] Sylvinite is the most important source for the production of potash in North America , Russia and the UK .
