Minerals
The Basics:
- Rocks are made of minerals but minerals are not made of rocks!
- Minerals all share 4 common characteristics: solid, inorganic, crystalline structure, and must have a definite chemical composition
- An Element is a "pure" substance made of only one type of atom
- Some minerals are made of only one type of element, such as gold, wheras some may be made of more than one type, such as quartz, which is made up of silicone and oxygen.

Luster
Metallic
Non Metallic
Cleavage and Fracture -see This Website for more examples
Cleavage - Tendency to split along definite crystalline planes, yielding smooth surfaces
Fracture - When minerals are stressed they shatter making no two pieces truly the same. There are two basic types of fractures, Conchoidal and Non-Conchoidal
Obsidian is an example of conchoidal fracture
