Study Notes

Properties of Minerals

Minerals are naturally occurring, inorganic solids with a definite chemical composition and crystalline structure.
Common properties used to identify minerals include hardness, luster, color, streak, cleavage, fracture, density, and specific gravity.

Identifying Minerals

Hardness measures a mineral's resistance to scratching, often evaluated using Mohs hardness scale.
Luster describes how a mineral reflects light; categorized as metallic or non-metallic.
Color is a visible characteristic but can be misleading due to impurities; streak test involves scraping a mineral on porcelain to reveal its powder color.
Cleavage refers to the tendency of a mineral to break along flat surfaces, while fracture describes an uneven break.

Density Lab Importance

Completing labs accurately is crucial; points are deducted for incomplete submissions.
Pay special attention to highlighted sections in your lab, particularly involving density measurements.
