halite
Sign in to saveHalite ( ), commonly known as rock salt, is a type of salt, the mineral (natural) 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 gray depending on inclusion of other materials, impurities, and structural or isotopic abnormalities in the crystals. It commonly occurs with other evaporite deposit minerals such as several of the sulfates, halides, and borates. The name halite is derived from the Ancient Greek word for "salt", ().
AI overview
Halite, commonly known as rock salt, is the natural mineral form of sodium chloride (NaCl) that typically appears as colorless or white crystals, though it can also be various other colors depending on impurities. It matters because it's a naturally occurring salt mineral that commonly occurs alongside other evaporite minerals and has practical applications as a source of salt.
