1. Earth Science Chapter 2, Lesson 2 Mineral Groups

2. Silicate Minerals Minerals that contain a combination of silicon and oxygen Minerals that contain a combination of silicon and oxygen Silicate materials make up 96 percent of the Earth’s crust Silicate materials make up 96 percent of the Earth’s crust

3. Silicate Minerals Feldspar Minerals Feldspar Minerals Most common minerals in the Earth’s crust Most common minerals in the Earth’s crust White and Pink grains in granite that are visible is feldspar White and Pink grains in granite that are visible is feldspar Because of it’s coloration, it used a lot in building construction Because of it’s coloration, it used a lot in building construction

9. Chrysolite

10. Beryl

11. Topaz

12. Chrysoprase

13. Jacinth

14. Amethyst

15. Nonsillicate Minerals Minerals that do not contain a combination of silicone and oxygen Minerals that do not contain a combination of silicone and oxygen Makes up only about 4 percent of the Earth’s crust Makes up only about 4 percent of the Earth’s crust

16. Nonsillicate Minerals Can be divided into 6 categories Can be divided into 6 categories Native Elements Native Elements Carbonates Carbonates Halides Halides Oxides Oxides Sulfates Sulfates Sulfides Sulfides

17. Sapphire

18. Think Back 1. What are the two basic types of minerals? What is the difference between them? 2. Why can native elements not be silicate? 3. What are the two most common elements in the Earth’s crust?
