Study Notes
Characteristics of a Mineral
- A mineral must be a solid substance.
- A mineral must be naturally occurring.
- A mineral must be inorganic, meaning it is not living and not made from living things.
- A mineral must have a fixed chemical formula, composed of specific elements.
Physical Properties of Minerals
- Crystal Habit: the external shape or form of a mineral, including platey, elongate, or equant shapes.
