The book describes spectral luminescent properties of a large group of minerals. This is the first publication of the kind that has no analogues in the scientific literature on the subject. Part I presents classification of luminescent substances in nature at several systematic levels: global luminescent geospheres, geochemical luminescent anomalies and crystal-chemistry systematization of luminescent minerals. New luminescence techniques are described: detection of luminescent properties of minerals (apatite, fluorite, calcite, plagioclases, scheelite, and other) versus their genetically-defined features; mineralogical analysis; models of luminescent haloes of kimberlite pipes, ruby bearing scarns, emerald-bearing rocks, etc. Techniques for luminescent sorting of minerals are also depicted. Part II summarizes spectroscopic luminescent properties of minerals. It includes photo-, X-ray-, and cathodoluminescence spectra, excitation spectra and time-decay parameters of...
