The Optical Properties of Minerals

  • H. H. Read

Abstract

Certain characters of minerals dependent upon light have already been considered. We have now to deal with the optical properties that are especially important in the study of the group of minerals known as the rock-forming minerals, that is, those that make up the common rocks of the earth’s crust. In this study, the rock-forming minerals are examined with the microscope and are either in the form of small grains or fragments or else in very thin slices. A microscope is also used in the examination of polished surfaces of ore-minerals. The description of the microscopes and of the methods of preparing the minerals for study with them is deferred until the principles of optics that underlie the study have been considered.
