Guided Notes on Identifying Minerals
Mineral Properties Each and every mineral has certain mineral properties. The properties of each mineral depends on the following;  1) The type of elements.
Mineral Identification. Color Most notable characteristic Caused by presence of trace elements or compounds Least reliable way to identify a mineral because:
Standard/Objective: S6E5.b. Investigate the contribution of minerals to rock composition..
DEFINITION OF MINERAL Naturally occurring, Inorganic Solid with a definable chemical composition and crystal structure Physical Properties Crystal Form.
Crystal Shape: Cubic Fluorite Crystal Shape: Dodecahedron Garnet.

Mineral Identification

Identify A Mineral Physical Properties Hardness How easily it can be scratched Mohs Scale Luster Way it reflects light Metallic or nonmetallic

Mohs scale

Identify A Mineral Specific Gravity The ratio of a mineral’s weight compared to the weight of an equal volume of water Streak The color of a mineral when it is in powdered form Depends on the softness of the mineral

Identify A Mineral Cleavage Minerals that break along smooth flat surfaces Mica Fracture Minerals that break with uneven (not planar) surfaces Quartz Other Magnetite – magnetic Calcite – light in 2 rays, fizzes with HCl acid
