  1. GEOL 1307 Physical Geology Exercise #2 Mineral Identification

  2. Distribution of Elements in the Solar System • Elements in the Sun • Carbonaceous Chondrites • Elements in the Earth’s Core • Elements in the Earth’s Mantle • Elements in the Earth’s Crust • Elements in the Earth’s Hydrosphere and Atmosphere

  3. Minerals in Earths’ Crust • Oxygen = 46.6 % • Silicon = 27.7 % • Aluminum = 8.1 % • Iron = 5 % • Calcium = 3.6 % • Potassium = 2.8 % • Magnesium = 2.6 % • All Others = 1.5 %

  4. Mineral Identification • Mineral Classes • Silicates • Oxides • Carbonates • Sulfides • Sulphates • Halides • Phosphates • Hydroxides • Native Elements

  5. Using Mineral Properties to Identify Minerals • Luster • Color and Streak • Hardness • Moh’s Scale of Hardness • Cleavage • Special Properties • Using the Mineral Tables
