Unformatted text preview: 3 ), Dolomite (CaMg(CO 3 ) 2 ), Siderite (FeCO 3 ), and Rhodochrosite (MnCO 3 ). (a) Examine the samples of dolomite and siderite provided, carefully listing the optical properties of each mineral. (b) Summarize on a separate sheet of paper the optical properties common to each of the carbonate groups, and the main differences between each (calcite group, vs. aragonite group). (c) Explain the differences between the minerals calcite, dolomite, and siderite. How can you tell these three minerals apart in thin section ?...
