The Colours of Opaque Minerals

A full analysis of colour in opaque minerals, together with descriptions of about 270 of the principle ore minerals as regards their crystal structures, electronic structures (where known) and quantitative colour data.

Part 1 The nature of light and colours; Planck's radiation law; the eye; subjective colour problems; quantitative colour vision; CIE chromatically diagram; illuminants; colour atlases; colour names; metamerism; defective colour vision. Part 2 Light and crystals: polarization state of light waves; classical oscillator models; dispersion; radiation of electromagnetic waves; photons; quantum mechanical models; classical bond models; molecular orbital theory; bank theory. Part 3 Reflected light: Fresnel equations; tensors; relative permittivity tensor; propagation of light through anistropic media; reflectances of oriented sections; colours of oriented sections; anisotropy (polarization) colour between crossed and uncrossed polars. Part 4 Mineral data - metals and stoichiometric alloys (including gold, copper, niggliite, arsenic, graphite); rmXn minerals (including algodonite, maldonite, chalcosine, acanthite, ikunolite, pentlandite); RX minerals (including galena, sphalerite, chalcopyrite, stannite, enargite, nickeline, covelline); thiospinels; stibnite; RX2 minerals (including pyrite group, marcasite group, arsenopyrite group, molybdenite, melonite, krennerite); skutterudite; sulphosalts (including tetrahedrite, bournonite, proustite); oxide minerals (including spinel group, rutile group, wolframite group).
