Crystallography and mineral optics

  • What is crystal optics in geology?

    Crystals may have a single optic axis, in which case they are uniaxial, or two different optic axes, in which case they are biaxial.
    Non-crystalline materials generally have no birefringence and thus, no optic axis..

  • What is mineral optics?

    Optical mineralogy involves studying rocks and minerals by studying their optical properties.
    Today, most optical mineralogy involves examining thin sections with a petrographic microscope.
    Petrographic microscopes have polarized light sources that illuminate a thin section..

  • What is optical crystallography?

    Optical crystallography is the branch of science that focuses on the optical properties of crystals.
    Also known as crystal optics, it describes the behavior of light in anisotropic media, such as crystals, in which the light behaves differently depending on which direction the light is traveling.Oct 16, 2019.

  • What is the role of crystallography in mineralogy?

    In particular, crystallography, the branch of mineralogy that deals with the formation and properties of crystals, plays a huge role in our lives.
    This is because knowledge of crystals and their properties, and the technology that comes from them, are fundamental to electronics, and to modern living..

  • Why do optical properties often coincide with crystal form?

    The optical properties depend on the manner that visible light is transmitted through the crystal, and thus are dependent on crystal structure, crystal symmetry, and chemical composition of the mineral..

  • Crystals may have a single optic axis, in which case they are uniaxial, or two different optic axes, in which case they are biaxial.
    Non-crystalline materials generally have no birefringence and thus, no optic axis.
  • Optical properties of minerals, such as absorption, refraction, polarization, pleochroism, birefringence, and optical sign, are used in mineral identification, characterization, and research.
1) Transparent (minerals that transmit light and images through them) e.g., selenite. 2) Translucent (minerals that only transmit light) e.g. quartz. 3) Opaque 
Optical crystallography is the branch of science that focuses on the optical properties of crystals. Also known as crystal optics, it describes the behavior of light in anisotropic media, such as crystals, in which the light behaves differently depending on which direction the light is traveling.

Do I need to measure every optical property to identify a mineral?

So, just like identifying hand specimens based on physical properties, it is not always necessary to check or measure every optical property to figure out what a mineral is

What is optical mineralogy?

The optical properties of minerals are characteristic and serve for mineral identification

The subject of optical mineralogy is extensive and is dealt with in many excellent books (for a partial listing, see “Further reading” at the end of this chapter)

Optical crystallography, branch of crystallography that deals with the optical properties of crystals. Minus an external crystalline form, a mineral can be identified by revealing its optical properties. All crystals may be assigned to one of five groups that correspond to the seven systems of crystallization.
