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.
