Halite

How to identify Halite:
Halite is also known as Rock Salt. It is usually white or colorless. It can also be light blue, dark blue, pink, red, yellow, gray and orange. Another characteristic is its salty taste.

Well crystallized specimens of halite cubes can be very impressive and popular. Some are colored an attractive pastel pink by inclusions bacterial debris that is trapped during crystallization in an evaporative lake. Often these specimens that are sold worldwide 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 imagination to enhance their inventory. They are putting sticks, animals skulls and other imaginative items into these lakes and retrieving them relatively short time later covered in clusters of white or pink halite cubs.
Luster:
Glassy

Cleavage:
The Cleavage is perfect in 3 directions forming cubes.

Uses:
Halite aka Rock Salt is used for many reasons. Such as seasonings for food, melting ice in the winter, salt licks for farm animals, to produce common salt and chlorine, and many other reasons.

One way people use Halite is for farm animals. The Halite is put into a block form and they call it a salt lick. The Farm animals lick this block of salt throughout the day. They do this because they do not get any salt in their diet. Their diet consists of alfalfa, grain, and occasional apple or carrot. These Salt licks help put some salt into their diet so then they don't get a disease called White Muscle Disease. This disease is where the muscle looks white instead of red; it can also lead to heart failure.

Salt is necessary for people and animals to have in their diets. It is used in the food industry and as rock salt to melt snow on roads. It is used to help keep food for long amounts of time, in ceramics, soap, nuclear reactors, and animal food.
Hardness: 2.5
Chemical Composition:
Sodium Chloride. Formula: NaCI.

Streak: white

How it forms:
Halite is a salt that is sedimentary. All salt comes from the sea in some way. If salt is found on land, it is because there was once a sea there that disappeared, leaving the salt behind. It is formed when water that contains salt evaporates and leaves the salt behind. If it is hard layers underground, it is called rock salt.

In smaller bodies of water, evaporation will make a vapor that rises. Then the salt in the water will form crystals and fall back into the water. When this happens over and over, a bed of salt is made. Salt is mined in differnet ways depending on where it is found or even made. For the salt that is found where seas used to be, underground mining can be used.

Where you can find Halite:
Halite can be found everywhere in the world. Halite is found in many current evaporative deposits such as near Salt Lake City, Utah and Searles Lake California ion 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 minded for road salt.

Check out how big these Salt Crystals can get. They are almost as tall as the dude in the picture.

Halte rock salt is used all round the world. It is to melt the ice of the roads people can bye it at the store and they us it for the drive ways so the cars dont slipe.

What's that on your chips? It's a mineral called halite! If you look closely at ordinary table salt, you will see that, just like other minerals, it looks like crystals. Halite is salt. In its natural form, it's called rock salt.external image halite2_med.JPG








Key Terms:
1. Cleavage: When certain minerals break into preferred directions to get more or less smooth surfaces.
2. Luster: When used in minerals, it means the nature of the mineral surface. Also considering it's reflective qualities.
3. Streak: Its the line of powder you get from rubbing a mineral onto a hard, rough, white surface. The streak helps determine the character of the mineral.
4. Halite: A soft, white, colorless mineral. It occurs in cubic crystals with perfect cleavage. The chemical composition is sodium chloride. Also known as Rock Salt.
5. Mineral: Any class of substances in nature. Neither a vegetable or an animal. A substance of chemical composition and it usually has a definite crystal structure.
6. Vitreous: Glass

Halite can be any color like white red, yellow, orange, pink, green, blue, violet, and gray.

Salt is produced in most of the countries on the earth. After the United States, the largest producers of salt are China, Germany, India, and Canada. In most other countries having a seacoast, salt for local use is produced by evaporation of seawater.

 DID YOU KNOW?!?

  • That Halite melts at 804°!
  • Halite colors are: Colorless, whitish, yellow, red, purple or blue




OUR CITES

Rock salt is mined underground deposits by drilling and blasting. Deposits are reached through a circular shaft, typically about 20 feet in diameter and as deep as 2,000 feet, depending on the depth and location of the salt deposit.

What they say is that all the salt of the Grate Salt Lake be give to every one in the world and there would be alot salt left. Tha is what Utah is is know for and if you go to the the Grate salt lake during the summer u can flote in the water becase of all the salt.

Halite rock rock salt is found all around the wourld. Itis where ther was a sea are a lake and it evaporated and all the salt was left behind and it turnd into salt. The salt is mined useing big trucks and that photo's that are one ther those are the trucks they use to get the salt.
