What minerals are found with apatite?

What minerals are found with apatite?

Apatite is a phosphate mineral (and is the most abundant phosphorous-bearing mineral). The name actually covers three different minerals (fluorapatite, chlorapatite and hydroxylapatite) depending on the predominance of either fluorine, chlorine or the hydroxyl group.

Does apatite have magnesium?

Synthetic apatites are widely used both in the dental and the orthopaedic fields due to their similarity in composition with the inorganic phase of hard tissues. Biologic apatites are not pure hydroxyapatite (HA), but are calcium-deficient apatites with magnesium and carbonate as minor but important substituents.

How do you identify an apatite mineral?

Physical Properties Apatite is best known for its use as an index mineral with a hardness of 5 in the Mohs Hardness Scale. It is usually green in color, but can be yellow, brown, blue, purple, pink, or colorless. These colors are often so vivid that apatite has frequently been cut as a gemstone.

Is apatite a rock or mineral?

The apatite Mineral Group. Apatite is named for the Greek word apate, which means “deceit”, since Apatite is similar in appearance to many other minerals. Apatite describes a group of similar isomorphous hexagonal phosphate minerals. The primary Apatite group includes Fluorapatite, Chlorapatite, and Hydroxylapatite.

Where is apatite mineral found?

Apatite is found in Myanmar (Burma), Brazil, India, Kenya, Madagascar, Norway, Sri Lanka, South Africa, Mexico, Canada and the United States. There are three minerals that actually contribute to apatite, which is the reason for the varied colors and shades of this stone.

What kind of stone is apatite?

What is apatite composed of?

Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH−, F− and Cl− ions, respectively, in the crystal.

What is apatite worth?

What is apetite mineral?

What is apatite made from?

Apatite is calcium phosphate combined with fluorine, chlorine or hydroxyl. These three minerals are usually found in every specimen but some specimens have been known to have 100% of one or the other. It is often hard to spot the difference between the three minerals in hand samples of this stone.

Is apatite a common mineral?

Apatite is very common as an accessory mineral in igneous and metamorphic rocks, where it is the most common phosphate mineral.

Is blue apatite expensive?

Blue apatite is also sometimes heat treated to enhance its color. Because apatite is quite commonly found and not expensive, synthetic versions are rare.

What are the 7 mineral tests?

Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

What are the tests used to identify minerals?

Geologists use the following tests to distinguish minerals and the rocks they make: hardness, color, streak, luster, cleavage and chemical reaction. A scratch test developed by a German mineralogist Fredriech Mohs in 1822 is used to determine mineral hardness.

Is apatite a precious gem?

Apatite is a naturally occurring gemstone, largely unknown to the general public but prized by collectors for its many different colors and forms. The most common gem variety is a translucent to transparent semiprecious gemstone that is steadily increasing in popularity within the jewelry trade.
