Presentation transcript:

Chap 3, Sect 2 (Identifying Minerals) Objectives: Identify 7 ways to determine the identity of minerals. Explain some special properties of minerals.

Tech Terms: luster– the way in which a mineral reflects light. streak – the color of the powder of a mineral. cleavage – the tendency of a mineral to break along smooth, flat surfaces.

fracture – the tendency of some minerals to break unevenly along curved or irregular surfaces. acid test – determines if a mineral contains calcium carbonate (silicate or nonsilicate) HCL acid

hardness – a measure of a mineral’s resistance to being scratched hardness – a measure of a mineral’s resistance to being scratched. Use Moh’s hardness scale. 7. density – the measure of how much matter is in a given amount of space.

Special Properties Minerals that glow under ultraviolet light have a property known as fluorescence. Magnetite –natural magnet. Uraninite –radioactive Calcite –reacts with acid. Quartz –produces a small electric current. It is used in microphone, radio transmitters, watches.
