Minerals Encyclopedia

Discusses over 600 mineral species & varieties. Covers not only the common minerals, including gemstones & previous metals, but also very rare minerals, known from only one locality. Frequency of the occurrence in nature is given as a symbol in the caption of each description, together with its crystal system, next to the name & the chemical formula. All the mineral species & varieties described are pictured in one or more color photos; some are also shown in form of massive aggregates, which is much more common in nature. Minerals are arranged into chapters according to the mineral system: elements, sulfides, halides, oxides, carbonates, borates, sulphates, phosphates, silicates, organic compounds, & rocks, meteorites & tektites.Korbel, Peter is the author of 'Minerals Encyclopedia' with ISBN 9780756764081 and ISBN 0756764084.
