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.
In geology and mineralogy, a mineral group is a set of mineral species with essentially the same crystal structure and composed of chemically similar elements. [1] Silicon-oxygen double chain in the anions of amphibole minerals. For example, the amphibole group consists of 15 or more mineral species, most of them with the general unit formula A ...
Halite (/ ˈ h æ l aɪ t, ˈ h eɪ l aɪ t / HAL-yte, HAY-lyte), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride (Na Cl). Halite forms isometric crystals .

This list includes those recognised minerals beginning with the letter H.The International Mineralogical Association is the international group that recognises new minerals and new mineral names; however, minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.
The thick halite beds of the Prairie Evaporite Formation are essentially impermeable, and numerous solution caverns have been artificially created in them to store natural gas and liquified petroleum gas products. [8] Storage of nuclear waste, carbon dioxide, and other waste products has also been discussed. [1]
Sylvite, or sylvine, is potassium chloride (KCl) in natural mineral form. It forms crystals in the isometric system very similar to normal rock salt, halite (NaCl). The two are, in fact, isomorphous. [5] Sylvite is colorless to white with shades of yellow and red due to inclusions. It has a Mohs hardness of 2.5 and a specific gravity of 1.99.
