O2 - Usually oxide of a metalExample UsesHematite Fe2O3Iron ore, pigmentCorundum Al2O3Abrasive, gemsMagnetite Fe3O4Iron oreII. Carbonates CO32-a. Common Sedimentary rock formersExample RockThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Calcite CaCO3LimestoneDolomite Ca, MG (CO3)2DolostoneIII. Sulfatesa. SO42- Common evaporate rock formersi. Example: Gypsum CaSO4 - H2O -> use: wallboard, cementii. Anhydrite: Gypsum without H2Oiii. Evaporate- evaporated sea waterIV. Sulfidesa.
