Web5 – Optical Mineralogy KEY CONCEPTS Light entering a crystal may be absorbed, refracted, or reflected. Optical mineralogy involves studying rocks and minerals by studying their optical properties. Today, most optical mineralogy involves examining thin sections with a petrographic microscope. All isometric minerals (e.g., garnet) are isotropic – they cannot reorient light. Light does not get rotated or split; propagates with same velocity in all directions. These minerals are always black in crossed polars.All other … See more
