Minerals are naturally occurring chemical compounds with an ordered crystalline structure, classified into silicate, oxide, carbonate, and phosphate minerals. Silicate minerals, which make up about 90% of the Earth's crust, form from the crystallization of molten rock, while oxide minerals consist of inorganic compounds with close-packed oxygen atoms. Carbonate minerals react with acid and are often found in marine sediments, while phosphate minerals are inorganic salts that are key components of teeth and bones in vertebrates.

MINERALS
Earth and Life Science

2. MINERALS
•It is a naturally occurring chemical compound that occurs
naturally in its pure form (organic solid form)
•It has an ordered crystalline structure

3. CLASSIFICATION OF MINERALS
•Silicate Minerals
•Oxide Minerals
•Carbonate Minerals
•Phosphate Minerals

4. SILICATE MINERALS
•Largest and most important mineral class
•Approximately makes up of 90 percent of the Earth’s Crust
•Created when molten rock matter containing oxygen and
silicon cools and solidifies, causing the crystallization of
different minerals at successively lower temperatures and
pressures
•Example: Quartz

5. OXIDE MINERALS
•Any naturally occurring inorganic compound with a structure
based on close-packed oxygen atoms in which smaller,
positively charged metal or other ions occur in interstices.
•Example: Corundum (Ruby and Sapphire), Chromite,
Magnetite

6. CARBONATE MINERALS
•Any minerals that tend to be brittle, many have rhombohedral
cleavage, and all react with acid.
•Most often formed as biogenic or chemical sediments in
marine environments.
•Example: Calcite, Magnesite and Dolomite

7. PHOSPHATE MINERALS
•Any of a group of naturally occurring inorganic salts of
phosphoric acid, H3(PO4).
•The main crystalline constituents of teeth and bones in
vertebrates.
•Examples: Iazulite, Triphylite, Monazite, Erythrite
