14. What makes up a mineral?

15. Mineral Facts: There are thousands of different kinds of minerals.
Many of the minerals come from magma cooling.
Some are formed from compounds dissolved in a liquid.
There are about 100 common minerals formed from the 8 most abundant elements from the Earth’s crust: aluminum, iron, calcium, sodium, potassium, magnesium, oxygen, and silicon.

20. Properties of Minerals
How to identify minerals…
Color
Luster – the way a mineral reflects light (metallic or non-metallic)
Hardness – the ability of a mineral to resist being scratched
Streak – powder scraped off is the same color as the mineral
Density
Crystal shape – 6 basic crystal shapes
Cleavage and fracture – how a mineral breaks
Special properties – individual properties that individual minerals have (ex. Magnetite is naturally magnetic)

21. Today’s Goals: Know how to tell if something is a mineral or not
Explain how color and luster are used to identify minerals

22. LUSTER
Luster refers to how light is reflected from the surface of a mineral.
Is it shiny? Does it look oily?

23. COLOR
Most minerals occur in more than one color.

24. Luster: Yes or No?
Yes

25. Luster: Yes or No?
Yes

26. Luster: Yes or No? No

27. Luster: Yes or No?
Yes (glassy luster)

28. Luster: Yes or No?
Yes

29. Luster: Yes or No? No

30. Why is color not the best property to use to identify a mineral?
