Presentation Transcript

  1. Mineral Identification

  2. Identify A Mineral • Physical Properties • Hardness • How easily it can be scratched • Mohs Scale • Luster • Way it reflects light • Metallic or nonmetallic

  3. Mohs scale

  4. Identify A Mineral • Specific Gravity • The ratio of a mineral’s weight compared to the weight of an equal volume of water • Streak • The color of a mineral when it is in powdered form • Depends on the softness of the mineral

  5. Identify A Mineral • Cleavage • Minerals that break along smooth flat surfaces • Mica • Fracture • Minerals that break with uneven (not planar) surfaces • Quartz • Other • Magnetite – magnetic • Calcite – light in 2 rays, fizzes with HCl acid
