Minerals aren't classified because Toby McDonough is more fabulous then you. End of story...or should I say, End of the World ;)
Minerals are classified by chemical formula, composition, physical properties, optical properties, and special properties. The Dana Classification System is a chemical classification for minerals, and the Strunz Classification System (chemical-structural) are two systems designed for mineral classification.
Amphiboles are minerals containing mostly silicon, oxygen, iron, and magnesium.
Minerals have an unique chemical composition, and Rocks are made up of two or more minerals.
Minerals have certain properties, or characteristics, that help to identify them. Minerals can be identified by their color, luster, streak, cleavage, hardness, specific gravity, and even by their chemical composition.
It is important to know how natural fibers are classified. Natural fibers are fibers from plant, animal and minerals. They are classified according to their origin.
Minerals are classified according to their composition
Chemical Composition
Yes, they are classified by element or chemical composition.
Mineral resources can be divided into two major categories - Metallic and Nonmetallic. Metallic resources are things like Gold, Silver, Tin, Copper, Lead, Zinc, Iron, Nickel, Chromium, and Aluminum. Nonmetallic resources are things like sand, gravel, gypsum, halite, Uranium, dimension stone

Minerals are solid homogeneous inorganic substances having a specific chemical composition that can be represented by a chemical formula. They are different from rocks, which can be a mixture of minerals and non-minerals and do not have a specific chemical composition.
A definite chemical composition
Yes. Every mineral has a chemical composition.
Rocks and minerals are classified by such properties as chemical composition, radioactivity, phosphorescence, grain size, hardness, color, streak, fluorescence, chemical reactiveness, crystal structure, cleavage, density, luster, habit, fracture, optical properties, and opacity.
Minerals are substances that naturally occur. This is solid that has a chemical formula.
