Since a lab later in the semester requires us to identify a number of minerals, I decided to include pictures of all the ones we identified in class last Thursday. Hopefully, all the pictures will be useful when studying.
Potassium Feldspar
Kaolinite
Obsidian
Quartz
On a side note, Quartz is the official state gem of Georgia. The state legislature designated it as such in 1976, specificially citing amethyst and clear quartz as examples.
Hornblende
Halite
Pumice
Micah
Amethyst
Galena
Limestone
Calcite
