Earth and Life Science - Classification of Minerals

This is a powerpoint presentation that is about one of the Senior High School Core Subject: Earth and Life Science. It is composed of the definition and the properties of the different classification of minerals.

1. CLASSIFICATION OF
MINERALS
Earth and Life Science

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

3. CLASSIFICATION OF MINERALS
•SilicateMinerals
•Oxide Minerals
•CarbonateMinerals
•Phosphate Minerals

4. SILICATEMINERALS
•Largestandmostimportantmineralclass
•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. OXIDEMINERALS
•Any naturally occurringinorganic compoundwith a structure
based on close-packedoxygenatoms in which smaller,
positively chargedmetalor other ions occur in interstices.
•Example:Corundum (Ruby and Sapphire), Chromite,
Magnetite

6. CARBONATEMINERALS
•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, H
3(PO
4).
•The main crystalline constituents of teeth and bones in
vertebrates.
•Examples:Iazulite,Triphylite, Monazite, Erythrite
