Optical mineralogy properties
WebThin sections are prepared in order to investigate the optical properties of the minerals in the rock. This work is a part of petrology and helps to reveal the origin and evolution of the parent rock. A photograph of a rock in thin section is often referred to as a photomicrograph. Thin sections are also used in the microscopic study of bones ... WebOptical properties are a striking expression of the anisotropic internal structure of minerals. The best way to convince yourself that this is true is to examine a thin section of a rock (a 20–30 μm thick slice, see Chapter 10) in a petrographic microscope with polarized light and compare the effects with those from a plain glass slide.
