"TOPAZ!" - Edited by Wendell Wilson, 80
pages, 8 1/2 X 11" size, illustrated, soft cover. There are two major articles in
this book: 1. "The Mineralogy, Geology, and Occurrence of Topaz", by M.A.
Menzies, and 2. "Pink Topaz From the Thomas Range, Juab County, Utah", by E.
Ford, W. Chirnside, F. Lichte, and P. Briggs, all from the U.S. Geological Survey in
Denver, Colorado. Topaz occurs in a range of fluorine-rich silica environments, from
plutonic through volcanic, and very rarely metamorphic. Gem crystals in cavities form
under more limited conditions, primarily in granite-derived pegmatites, greisens and rarer
hydrothermal veins, as well as in some rhyolites. Such deposits, worldwide, produce a
variety of habits and colors of this popular mineral and gemstone. Menzies has provided an
outstanding 48 page "mini-book" covering the mineralogy and geology of noted
worldwide Topaz occurrences, and has included a collection of nearly 40 superb color
photographs of crystallized Topaz from around the world. The color photographs are
supplemented by several black and white photos of specimens, line drawings of Topaz
crystal habits, and several tables -- one of the tables lists 45 of the world's most
important gem and mineral localities where notable Topaz gems and/or specimen material
have been found. The article on the Topaz from the Thomas Range in Utah covers the geology
and mineralogy, and has a complete list of all of the accessory minerals identified from
the rhyolite of the district. Also included are several other short papers on Topaz,
reprinted from the Feb. 1995 FM-TGMS-MSA Symposium on Topaz. This soft cover book was
published by the Mineralogical Record, Inc., Tucson, AZ, as Vol. 26. No. l -- the Jan-Feb
1995 special issue entitled "Topaz!" Shipping weight: 2 pounds Order Item: MR26-1 Price: $15.00 |
