Halite is the common table salt, NaCl. It forms cubic crystals, or can be massive, compact or granular. It is most often white when pure, but can also be coloured by impurities and be purpleish, reddish, yellowish, orange or colourless.
A mineral is a substance that usually. is an inorganic solid. (elemental mercury is an exception) allowing sulfates and halides to precipitate where the water evaporates. Native gold. Rare specimen of stout crystals growing off of a central stalk, size 3.7 x 1.1 x 0.4 cm, from Venezuela.
Mineral classification can be an organizational nightmare. With over 3,000 different types of minerals a system is needed to make sense of them all. Mineralogists group minerals into families based on their chemical composition.
Mineral of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides).

A mineral is a chemical compound with a given composition and a defined crystal structure. A rock is a mixture of one or several minerals, in varying proportions. A rock has only two of the characteristics minerals have–it is a solid and it forms naturally.
Halide minerals are a group of naturally occurring inorganic compounds that are salts of the halogen acids and encompass minerals with a dominant halide anion (F−, Cl−, Br−, and I−). Complex halide
The mineral gold is made of atoms of the element gold. The atoms are arranged in a cubic pattern. Crystals of gold form cubes because of the way is an oxide mineral. Halides are miner als that contain the elements fl uorine, chlorine, iodine, or bromine. Fluorite and halite are halide minerals. Carbonates are

MINERALS SORTED BY MINERAL GROUP . Most minerals are chemically classified as native elements, sulfides, sulfates, oxides, silicates, carbonates, phosphates, halides, nitrates, tungstates, molybdates, arsenates, or vanadates. More information on and photographs of these Gold commonly occurs in microscopic amounts in the earth and in
Halides are minerals composed of the halogen elements (fluorine, chlorine, bromine, iodine) with a metal (eg, halite or table salt, fluorite). Halides are generally soft, brittle and light in

· Gold nugget (placer gold) from Colorado, USA. (DMNH 10549, Denver Museum of Nature & Science, Denver, Colorado) A mineral is a naturally occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally occurring solid chemical.
