Quartz is found in almost every geological environment. It is a common constituent in most of the rock types and soil groups. Granite, sandstone, limestone, and most of the igneous, sedimentary, and metamorphic rocks contain quartz. Quartz contains mainly oxygen and silicon. These two constituents make upto 75 % of the earth’s crust. An alternate name for the Quartz Group is the Silica Group.

If rocks could talk distribution OAGEE Session 616 Oct 17Mining Matters
Session 616: PowerPoint presentation used to lead the 2-hour workshop session at the 2014 OAGEE Conference at Ryerson University, Toronto, ON
Session Description: A Mining Matters teacher-facilitator will lead this hands-on session for middle school teachers (grades 7-9) while they identify various rock building minerals, investigate the rock cycle and the characteristics of the three rock groups as well as discover the interrelationship between them. Particular attention will be given to rocks and minerals of Ontario. This workshop will enhance your skills, confidence, and knowledge of Earth sciences and invigorate classroom instruction.
12. What determines if something is a mineral? Naturally occurring solid Crystal structure inorganic definite chemical make-up
13. What do you think? Which of these are minerals? Sand petroleum gold coal glass rubies diamonds water Here is a hard one – What about ice?
14. III. How do geologists identify minerals? 1. One way is color! http://www.minresco.com http://www.prettyrock.com http://www.gems-afghan.com http://www.globalcrystals.com
15. 2. A mineral's hardness helps identify it. Not all minerals have the same hardness. Some you can easily scratch with your fingernail! /vwdocs/vwlessons http://www.wpclipart.com http://www.infowest.com http://www.wpclipart.com http://www.prettyrock.com
16. 3. Streak test Streak is the color of a mineral powder. Many minerals appear a different color when powdered than they do as a big piece. The color may be entirely different, or it may be a different shade. http://cmsc.minotstateu.edu http://cmsc.minotstateu.edu http://www.uky.edu/KGS
18. 5. Minerals also have different densities. This means for equal size, they have their own special weight. Which one is worth more? How could you tell? http://www.palagems.com A scientist would measure their densities and they would be different! The first one is topaz (worth a lot) and the second is citrine quartz (not worth a lot).
20. 7. Another property is the way a mineral breaks. Fracture means it breaks in a random pattern that cannot be predicted. Cleavage means it breaks the same way every time. www.visionlearning.com donsmaps.com Calcite and halite break a special way. Quartz and chert break in a random pattern. There is not way to predict how they break. www.mrsciguy.com
