Geology of Gem Deposits

Geology of Gem Deposits book

Topics in Mineral Sciences Volume 37

Editor: L.A Groat

Gem deposits are rare because in general the conditions that promote their formation are unusual and thus worthy of scientific study. Modern geological and analytical techniques have been applied to gem occurrences in Canada and elsewhere, and our models and understanding of their formation are being radically altered.

Short course volume 37 looks at gemstones from a geological perspective and reviews our current understanding of diamond, ruby, sapphire, jade, and emerald deposits and the lesser-known coloured gems.

Description

Gems have been prized for thousands of years, for their colour, lustre, transparency, durability, and high value-to-volume ratio. Because many gems are produced from relatively small, low-cost operations in remote regions of developing countries it is difficult to obtain accurate statistics regarding production and value…

In this handbook, we concentrate on the geology of gem deposits. For logistical reasons we concentrate on those varieties that are most significant in terms of the world gem trade (chrysoberyl, diamond, emerald, non-emerald gem beryl, jade, ruby, sapphire, tanzanite, topaz, tsavorite.) In addition, there is a chapter on gem-bearing pegmatites and on coloured gem occurrences in Canada. Gem materials not addressed in this volume include amber, amethyst, chalcedony, garnet, lazurite, malachite, opal, peridot, rhodonite, spinel, and turquoise, some of which might be included in a subsequent edition.
