Geologists define mineral as a hmogenous naturally occurring substance with a definable internal structure . Minerals are found in varied forms in nature , ranging from the hardest diamond to the softest talc .
Rocks are combination of homogenous substances called minerals . Some roks , for instance limestone , consists of a single mineral only , but majority of the rock consists of several minerals in varying proportion , although over 2000 minerals have been identified only a few of abundantly found in most of the rocks .
A particular mineral that will be formed from a certain combination of elements depend upon the physical and chemical condition under which the material forms. This , in turn , results in a wide range of colours , hardness , crystal form lascia and density that a particular mineral possesses geologists use these properties to classify the minerals .
Minerals are usually found in ores . The term is used to describe and accumulation of ornamental mixed with the other elements . The mineral content of the Year must be insufficient concentration to make its extraction commercially viable .
