WebAug 30, 2013 · 6. Mineralogy A mineral is a naturally occurring substance that is solid and stable at room temperature, representable by a chemical formula, and has an ordered atomic structure. It is different from a rock, which can be an aggregate of minerals or non-minerals, and does not have a specific chemical composition. Optical mineralogy involves studying rocks and minerals by studying their optical properties. Some of these properties are macroscopic and we can see them in mineral hand specimens. But generally we use a petrographic microscope, also called a polarizing microscope (Figures 5.1 and 5.2 show examples), and … See more Before starting a discussion of optical mineralogy, it is helpful to take a closer look at light and its properties. Light is one form of electromagnetic radiation (Figure 5.6). Radio waves, … See more The vibration direction of a light wave (which is the direction of motion of the electric wave) is perpendicular, or nearly perpendicular, to the direction the wave is propagating. In … See more [In the discussion below, references are made to crystal systems and to crystallographic axes. But we do not talk about them in detail … See more
Some minerals are colorless and transparent (quartz, calcite, feldspar, muscovite, etc.), while others are yellow or brown (rutile, tourmaline, biotite), green (diopside, hornblende, chlorite), blue (glaucophane). Many minerals may present a variety of colors, in the same or different rocks, or even multiple colours in a single mineral specimen called colour zonation. For example, the mineral tourmaline … WebJul 19, 2014 · Optical Mineralogy. WS 2012 /2013. Crystal systems and symmetry. The crystal systems are sub-divided by their degree of symmetry….
