What does halite mean?
Halite is the naturally occurring mineral form of sodium chloride, the chemical compound familiar as ordinary table salt. It commonly forms clear, pale, cubic crystals and can accumulate in thick beds or domes created by the evaporation of saline water. Geologists use the word when identifying particular minerals or reconstructing environments in which seawater or brine once evaporated. In industrial contexts, halite may also mean rock salt obtained by mining. Refining and processing this mineral produces much of the salt consumed at the table, although culinary “salt” can also have a broader meaning that includes other mineral salts. Halite is therefore useful when precision matters: it distinguishes a specific mineral and its geological history from salt in the more familiar culinary or general sense.
nounHalite is the mineral form of sodium chloride, commonly known as salt. It also refers to naturally occurring rock salt, especially when used in geology or descriptions of mineral deposits.
- The mineral sodium chloride, typically occurring as clear or pale cubic crystals.
- Naturally occurring rock salt, especially as a deposit or geological formation.
"The researchers discovered extensive halite deposits beneath the basin."
"The mine produces halite from a deposit thousands of metres below the surface."
"Thin layers of halite provide geological evidence of an ancient saline environment."
A rare plural used when referring to individual specimens or distinct occurrences of the mineral.
"The collection contains several unusually large halites from the deposit."
Table salt is refined halite: the familiar kitchen crystals began as a natural mineral.

Where does halite come from?
Halite is a 19th-century English scientific formation based on a Greek word meaning “salt,” with the mineral-suffix element “-ite.” The same Greek salt root also underlies words such as halide and halogen, while halo comes through a related Greek form. Together, these words preserve the long history of salt’s importance in language, chemistry, and commerce.
How halite is actually used
Halite is primarily a technical term used in geology, mineralogy, and the salt industry. In general writing, “rock salt” is usually more immediately understandable, while “salt” may also refer to other chemical compounds or to salt used in culinary contexts.
Easily confused with halite
Halite is sodium chloride, whereas hyalite is a variety of opal sometimes containing water.
