Certain Physical Properties of Minerals

  • H. H. Read


Minerals possess certain physical properties that are considered in this chapter in the following order:
  1. (i)

    Certain characters depending upon light, such as colour, lustre, transparency, translucency, phosphorescence and fluorescence. Other optical properties especially valuable in the recognition of minerals in thin section under the microscope are dealt with in a later chapter.

  2. (ii)

    Characters depending upon certain senses, such as those of taste, odour and feel.

  3. (iii)

    Characters depending upon the state of aggregation, such as form pseudomorphism, polymorphism, hardness, tenacity, fracture, cleavage, and surface tension effects. Crystallography—the study of crystals—is considered in the next chapter.

  4. (iv)

    The specific gravity of minerals.

  5. (v)

    Characters depending upon heat, such as fusibility.

  6. (vi)

    Characters depending upon magnetism, electricity and radio-activity.
