Книга: Geology of Gems
|Узнать о поступлении|
Geology of Gems is the first comprehensive English language publication to place gem deposits into a concise geological and genetic framework which provides an understanding of existing deposits and the environments of their formation. The book is international in scope and covers most major deposits, although there is a strong emphasis on former USSR and Russian Federation deposits. Eighteen chapters are devoted to specific gems (Precious Corundum, Beryl, etc). Each chapter contains historical and mineralogi-cal data, with discussions regarding chromophores responsible for various varieties. Major gem deposits and districts are described for each country relative to a geological-genetic classification. The text is liberally illustrated with geological and geographic maps, sections (with scales) and other figures, as well as with numerous, excellent colour photographs.
