Mineral Observations Pg. 24 Write down each mineral Mineral Observations Pg. 24 Write down each mineral. Skip a line between mineral names. 1. Halite- 2. Calcite- 3. Magnetite- 4. Apatite- 5. Sulfur- 6. Mica- 7. Pyrolusite- 8. Pyrite- 9. Feldspar- 10. Fluorite- 11. Olivine- 12. Bauxite- 13. Quartz- 14. Hematite- 15. Barite-

As you walk around the stations, write down observations about the mineral samples. You will have 30 seconds at each station. Name:________________ Observations: Color:_____________ Shiny or not shiny? Smooth or rough? After you are done: What characteristics do all minerals have in common?

What is a Mineral? Mineral- a natural, usually inorganic solid substance with a crystal structure. Inorganic=nonliving Pyromorphite

What do all minerals have in common? Are formed by natural processes. Are NOT alive and NEVER were alive Are solids with a definite volume and shape. Are elements or compounds with a unique chemical makeup Are made up of particles that are arranged in a pattern that is repeated over and over (called a CRYSTAL)

Crystal forms(add under #5) A.euhedral crystal Ideal crystal form= good crystal faces Grow in open spaces

Crystal forms(add under #5) B. anhedral crystal -not ideal crystal form=No crystal faces - Grow in tight spaces Sulfur Calcite

Crystal forms(add under #5) C. subhedral crystal - Between a euhedral and anhedral crystal. Most naturally occurring minerals grow in less than ideal conditions (such as growing with limited space) and therefore are often subhedral or ahedral crystals. Pyrite Hornblende

Minerals in the Earth’s Crust More than 3000 different types of minerals, but only 20 are common. Quartz(SiO2)is the most common mineral in the Earth’s crust.
