THE MINERAL HALITE

  • Chemistry: NaCl, Sodium Chloride
  • Class: Halides
  • Uses: Major source of salt and as mineral specimens.
  • Specimens

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. The right way is to first lick your index finger, rub it against the specimen and then taste the finger. This limits the amount of the mineral that actually gets in your mouth, an important consideration when you consider that there are poisonous minerals that resemble halite.

Halite is found in many current evaporative deposits such as near Salt Lake City, Utah and Searles Lake, California in the U.S., where it crystallizes out of evaporating brine lakes. It is also found in ancient bedrock all over the world where large extinct salt lakes and seas have evaporated millions of years ago, leaving thick deposits of salt behind. The cities of Cleveland and Detroit rest above huge halite deposits that are mined for road salt.

Perfectly formed cubes of halite are typical of the habit of this mineral. However it does form some unusual interesting habits that are much sought after by collectors. One habit is called a hopper crystal which forms what has been termed a skeleton of a crystal. Just the edges of a hopper crystal extend outward from the center of the crystal leaving hollow stairstep faces between these edges. Hopper crystals form due to the disparity of growth rates between the crystal edges and the crystal faces.

Another habit of interest is the vein filling fibrous habit found at Mulhouse, France and at some other localities. Often specimens are brightly colored purple and blue and with the silky luster due to the fibers, they represent a wonderful and a very uncharacteristic variety of halide. These specimens are a must have for teachers of mineral identification classes that want a stumper for those end of the session ID exams. Of course they are still easy to identify with the oft forgot simple taste test.

Well crystallized specimens of halite cubes can be very impressive and popular. Some are colored an attractive pastel pink by inclusions of bacterial debris that are trapped during crystallization in an evaporative lake. The pink color can fade with time and/or exposure to sunlight.

Often the specimens that are sold world wide in rock shops and in mineral shows were grown within the past year. In fact, the crystals form so fast and so well in some evaporative lakes that mineral dealers are using their imaginations to enhance their inventory. They are putting sticks, animal skulls and other imaginative items into these lakes and retrieving them a relatively short time later covered in clusters of white or pink halite cubes.

PHYSICAL CHARACTERISTICS:

  • Color is clear or white but can be found blue, purple, pink, yellow and gray.
  • Luster is vitreous.
  • Transparency: Crystals are transparent to translucent.
  • Crystal System is isometric; 4/m bar 3 2/m
  • Crystal Habits are predominantly cubes and in massive sedimentary beds, but also granular, fibrous and compact. Some crystals show a crystal type called a hopper crystal discribed above.
  • Cleavage is perfect in three directions forming cubes.
  • Fracture is conchoidal.
  • Hardness is 2
  • Specific Gravity is 2.1+ (light)
  • Streak is white.
  • Associated Minerals include other evaporite deposit minerals such as several sulfates, halides and borates.
  • Other Characteristics: Salty taste.
  • Notable Occurrences include Searles Lake, California and Utah in the U.S., Germany, and Mulhouse, France.
  • Best Field Indicators are taste, cleavage and crystal habit. Note that the similar halide sylvite (potassium chloride) has a distinctively bitter taste, and does not powder as easily with a knife blade.

Wt: 10.2oz
Searles Lake, California, U.S.A.
This lovely Halite specimen is colored pink by bacteria that were trapped when the salt precipitated out of solution. Its largest crystals approach 1 inch in all dimensions and show good examples of a form known as "hopper crystals," wherein the face of a crystal has formed concentric depressions in the shape of said crystal. Salt is delicate and highly soluble, and so should be kept in a safe, dry place.

The only word fit to describe this item is "unique". It is a cattle skull (minus the horns, unfortunately) that has been half covered with a thick crust of crystalline pink halite! It's huge! The pink halite crystals achieve hoppered cubes that are 2" long on each side maximum. This is really an amazing specimen that we probably won't be able to replace.

This specimen is quite different from most of the halite pieces that I've seen. For instance, the crystals(which are all interlocked into a form that resembles a stalactite) are all a translucent white color with zones of transparency. Secondly, the faces are all clean and smooth-- there are no "hopper faces"! On top of all of that, the specimen comes from way up north in Canada, one of my favorite places!

Wt: 11.7 oz
Searles Lake, Trona, California, U.S.A.
This specimen is basically made up of a cluster of pink halite crystals- like most other evaporite products, it has no host rock. On the faces where it was not separated from the salt crust it came from, there are crystals up to 1 inch long or more along the edge. They all possess the cubic shape and waxy luster of salt crystals, and all show evidence of the "hopper effect". Their pink color is common for Searles Lake halite, and comes from the presence of bacteria trapped in the crystals.

Wt: 1 lb., 0.9 oz. (479 g)
Searles Lake, Trona, California, U.S.A.
This specimen consists of part of a Halite crust. It is made up of hundreds of intergrown cubic crystals that range in size from a few millimeters to 0.8" (2.0 cm) along an edge. All have a pale pink color and pearly to waxy luster, and are translucent. Their cubic forms show definite hopper effects, and all are in very good condition, with little discernable damage. As exposure to light causes the specimen's pink color to fade, it is best to store it in a box, out of which one can take it for display or examination.

What looks almost like a stalactitic Halite formation comprises this large hand specimen. It is made up of hundreds of intergrown Halite cubes that are aligned directionally with each other. These cubes range in size from 0.1" (3 mm) or less up to 1.3" (3.3 cm) and are in excellent condition, showing only a small amount of human-induced damage. Their form is excellent- edges are well-defined and faces are clean, possessing a pearly luster. Only the largest crystals show any of the "hopper effect" that is common with Halites from the U.S. state of California. All have a milky-white color and are basically translucent, though a few show patches of colorlessness and clarity. There is no host rock present.

A cluster of intergrown Halite cubes makes up this hand specimen. These cubes range in diameter from a few millimeters to nearly 1.1" (2.8 cm) and are generally in very good condition, showing only a small amount of damage. Their cubic form is excellent, and like most Halite crystals from this locality, demonstrate the "hopper effect" that occurs when the edges of a crystal grow more quickly than its faces. All have a uniform pale pink coloration (caused by bacteria trapped within) and a bright pearly luster. The cluster is basically translucent, but some edgeward crystals show a very faint transparence in areas. There is no host rock present.

I cannot tell if this Halite specimen is actually stalactitic in nature- however, I think that it is, as it only shows fresh damage at one end. It consists of scores, or perhaps hundreds of intergrown Halite cubes that are in excellent condition and reach diameters of nearly 1" (2.5 cm). All have excellent cubic form, with well-defined edges and clean faces that possess a waxy luster and show no "hoppering". All have a milky-white color and are translucent to dimly transparent. Several show a thin layer of clarity that runs along one plane near the center of each crystal (see the second image). There is no base or host rock present, though there are tiny bits of a reddish material stuck to the piece (these could be made of halite, however).

This hand specimen is made up almost entirely of partly intergrown Halite cubes. These cubes are generally in excellent condition and measure as much as 0.9" (2.3 cm) along an edge. All have excellent cubic form, though one or two are slightly warped, and all show the "hopper effect" which is standard for Halite from this locality. Their color is a pale pink and they have a pearly luster. Though a few may show patches of transparence, they are generally translucent. The crystals rest on a more massive bed of Halite that may be mixed with an indeterminate amount of trona.

Dozens of large Halite crystals rest on the more massive Halite crust of this specimen. These crystals reach over 1" (2.5 cm) in diameter and are in excellent condition, showing almost no damage. Their cubic form is likewise excellent- they occur in a hopper form, wherein the edges of each crystal grew more quickly than their faces, creating depressions that are graduated by concentric "steps". All have the pink color that is common for Halite from this locality, and their luster is pearly at beast. They are generally translucent, though most contain patches of transparence. The color fades drastically to white at one point on the base, which I believe contains a substantial amount of trona.

Searles Lake, San Bernardino cty., California
This is a nice specimen of pink halite crystals resting on a piece of evaporite matrix. The largest crystal measures nearly 1.2" (3.0cm) across. Several of these crystals exhibit hopper-growth, a condition occuring when crystal edges grow more quickly than the centers. The pink color is due to algae in the crystallizing solution. There is only very minor damage to this specimen.

This is an interesting halite specimen, due to the random pattern of purple color zones inside the crystal. I suspect that all of the faces are either cleavage or fracture, but I do note that the surfaces that I think are "fracture" do not show a normal conchoidal fracture pattern, and indeed look more like surface striations.

This large halite crystal has a natural termination on the top surface, but entirely cleavage or fracture surfaces elsewhere. The coloring is interesting, as the bottom of the crystal is clear and colorless, and towards the top are numerous zones of color. Mostly, the zones are a deep purple and are vertically oriented. There are some horizontal blue color layers, also,

This is a very nice halite specimen. It is extremely transparent, and part of the crystal is colored blue from three orthogonal planes of parallel color-defect zoning. The blue color is a crystal ion defect effect - it would disappear if the specimen was disolved. Five surfaces are cleavage, and one looks fractured - there are apparently no original crystal surfaces. Still, the specimen is appealing. From one side, there are a dozen or more horizontal blue zones. From the front, there are additional parallel blue zones at a 45 degree angle. And from the top, there is a cross-hatch of color zones at right angles. This is a very nice cabinet specimen.

This large cabinet specimen of halite is a beautifully patterned blue color. The blue splotches appear nearly random from most angles, but are clearly layered from some viewpoints. Other than the blue color zones, the halite is transparent, colorless, and very transparent. There do not appear to be any original crystal surfaces - rather, most surfaces are cleavage, with some obvious fracture surfaces breaking the symmetry of the orthogonal cleavage planes. There are some very interesting patterns visible on the surface. The overall appearance is a deep and pretty blue. This specimen shows well when backlit. However, it is halite, and should be kept in a dry cabinet OR shuld be constantly illuminated (via a warm light source) to keep its temperature slightly above ambient to prevent humidity from pitting the surface.

because it presents so nicely. It is a cluster of hoppered pink halite cubes perched on a non-descript host rock (it may just be dirty, massive halite). The top of the rock is colored pink by a thin, porous coating of halite. The bottom of the specimen is covered with hundreds of small perfect cubes of clear, colorless halite. To my eye, the color of the larger crystals is a nice pink, with no hint of the orange that seems to show up in our (unretouched) photos.

This is a beautiful specimen of halite (table salt). It is complete - I see no attachement points. It is completely formed of cubic crystals of colorless halite, which have a white appearance over-all due to internal fractures and milky inclusions. The intergrown crystals are arranged in several spires of stacked crystals which look like just two spires until closely examined. Some of the smaller crystals are very transparent, and many crystals show color zoning - one half colorless, the other half milky. THe one imperfection I note is that (before I purchased it) the specimen appears to have been stored on cotton which became damp, and some of the cotton fibers have adhered to parts of the specimen. I have removed most of them, but the vitreous luster is dulled where the moisture touched the surface.

I believe that this is a stalactite of halite. It is pretty, consisting of several lines of intergrown cubes of white halite. The attachement point is not obvious in that there is not a clear breakage point, but one end (the only end to show any damage at all) must be the starting point of the stalactite, as the lines of crystals appear to flow from there. Careful mounting will yield an impressive specimen.

Three intergrown halite crystals comprise this specimen. One is only a fraction of a complete crystal, and forms the base. The other two, while incomplete, are still nicely aesthetic, strongly hoppered crystals with a pink color. Some portions of the crystals are colorless and very transparent, but overall the halite is colored pink by inclusions of bacteria.
