C). CSI Minerology As we went from station to station, we looked at each minerals physical properties which lead us down certain paths that would tell us what the mineral was called. We examined fifteen different minerals in total. The first one, was located in the non-metallic (dark colored) luster category and was harder than glass and did not have cleavage present, it's harness=7 and was dark browish, this mineral was known as Smoky Quartz. For the second mineral, this one was in the nonmetallic (light colored) category and was harder than glass, had cleavage present, and had a hardness of 6, this mineral was known as Plagioglase feldspar. For the third mineral, it was also in the light colored nonmetallic luster category and had cleavage present and a hardness of 2-2.5. This mineral was known as Muscovite. The fourth mineral was in the dark colored nonmetallic category and was harder than glass and did not have cleavage present, it was olive green and had a hardness of 6,5-7. This mineral was Olivine. The fifth mineral, was in the light colored nonmetallic section and had no cleavage and a hardness of 7 (harder than glass) this mineral was Quartz. The sixth mineral, was a metallic luster that was harder than glass and had a black streak, this mineral was magnetite. The seventh mineral was a light colored nonmetallic and had cleavage present as well as a harness of 6 (being harder than glass) this mineral is known to be Potassium feldspar. The eight mineral was light colored nonmetallic and had cleavage present and was sorter than glass. This mineral was white or almost colorless and was known as Halite. The ninth mineral was a metallic luster with a hardness of 1 and had a dark grey streak. This mineral was graphite. The tenth mineral
