Halite is composed of sodium and chlorine in equal proportions (NaCl). Rock salt and halite are not exactly synonymous terms. Halite is a mineral, rock salt is a type of rock that is predominantly composed of halite. Halite is an evaporite mineral. These are water-soluble minerals that crystallize out of concentrated aqueous solutions.
From the Greek άλς, sea, for halites, later modified by J.D. Dana to halite.
Halite (/ ˈ h æ l aɪ t / or / ˈ h eɪ l aɪ t /), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride (Na Cl). 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 the amount and ...
There are poisonous minerals that resemble halite. By using your finger you can keep yourself safe. Uses Halite has many uses. We get our table salt from it. In cold climates salt is used to control ice on roads and sidewalks. It is used to soften water and as an ore for sodium and chlorine. ... Fracture: conchoidal Other Characteristics: salty ...

Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. As discussed in the "Earth's Minerals" chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in Figure 5.
Hydrohalite is not strictly a variety of halite, but a very rare, similar mineral with the formula NaCl + 2H2O. This variation forms only under very unique conditions where the water does not dissolve the salt and becomes an integral part of the structure of the mineral. ... Conchoidal. 2.1 - 2.6.

In sedimentary environments, calcite most often occurs as limestone rock or as marble, which is metamorphosed limestone. In these rocks, calcite is often the only mineral present, but in some sedimentary environments, calcite may be associated with dolomite, gypsum, anhydrite, chert, or halite.
Halite, better known as rock salt, can easily be distinguished by its taste.Since taste is an important property of salt, there is a right way to taste a specimen of halite (or an unknown mineral that is similar to halite) and a wrong way.
Halide mineral, any of a group of naturally occurring inorganic compounds that are salts of the halogen acids (e.g., hydrochloric acid). Such compounds, with the notable exceptions of halite (rock salt), sylvite, and fluorite, are rare and of very local occurrence.
Despite being a common, iron-rich mineral, pyrite is rarely mined for its own sake, and most of our iron is produced from magnetite and hematite deposits. Those iron oxide minerals occur in larger concentrations and volumes than pyrite, so they are a more economical iron source.
Identifying Minerals. Identify and classify common rock forming minerals. ... In introductory geology, the key fracture types to remember are irregular, which most minerals exhibit, and conchoidal, seen in quartz. Crystal Shape. ... Halite, NaCl, is a halide mineral. Sulfates.
Halite is the same thing as the common tablesalt. It is very common in arid parts of the world. It forms when parts of the oceans is cut of and dries out (as the Mediterranean Sea once did) or in seas without outlets (for example The Dead Sea).
PHYSICAL GEOLOGY MINERAL IDENTIFICATION HELP SHEET By Dr. George Hudak (You must be able to identify these minerals on the lab exam)
The sure way to determine if a mineral is halite is to taste it. However, don't stick an unknown mineral sample in your mouth just in case it is poisonous. Instead, lick a finger and rub it against the mineral specimen that you think is halite. ... Fracture: Conchoidal ; Last modified April 15, 2003 by Lisa Gardiner. Shop Windows to the ...

Halite occurs in vast beds of sedimentary evaporite minerals that result from the drying up of enclosed lakes, playas, and seas. Salt beds may be hundreds of meters thick and underlie broad areas. In the United States and Canada extensive underground beds extend from the Appalachian basin of western New York through parts of Ontario and under much of the Michigan Basin.
The fracture that is commonly found exhibited by Halite is usually conchoidal when the mineral is examined under petrographic microscopes. The hardness measure of the mineral when it is evaluated using the Mohs scale method is usually 2.
Description. A mineral composed of sodium chloride that naturally occurs as colorless, cubic crystals. Halite is found in dry lakebeds, in underground salt deposits and near the ocean. Large deposits occur in Germany, Austria, Russia, France (Dax), India (Punjab), Canada (Ontario), and the U.S.

Halite: Non-metallic: Softer than glass: 3 perfect cleavages at 90°; Tastes like salt, feels greasy. Gypsum: Non-metallic: Softer than glass and softer than a fingernail: Generally clear to white; One perfect cleavage, may show up to 3 cleavages; Easily scratched with a fingernail.

Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lake s. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet.
Halite, commonly known as rock salt, is the mineral form of sodium chloride (NaCl). Halite forms isometric crystal. The mineral is typically colorless or white, but may also be with shades of light blue, dark blue, purple, pink, red, orange, yellow or gray depending on the amount and type of impurities.
