This is a 9" x 12" softcover book with 240 glossy color pages and over 1000 photos and diagrams. Agate and jasper structures are shown in macro-photography, micro-photography, and in representative thin-sections. The books weighs just under 3 lb. (1.5 kg.), so international shipping is expensive.
The first section explains the genesis of agates and provides diagrams of their internal structure with thin-section examples. This is followed by several sections showing example photographs of fortification agates, plume agates, moss & tube agates, sagenitic agates, and other varieties. Limited locale information is provided.
The next section explains the formation of jasper with examples of structural characteristics again using several thin-sections. It discusses much of the market misnaming of a host of materials as jaspers. This is followed by many sections with photographic examples of generic jaspers, brecciated jaspers, orbicular jaspers, and scenic jaspers.
Finally there is a short section with a discussion of rhyolites and their confusion with jaspers. Followed by an even shorter section on fossilized materials. Both of these sections have abundant photo-examples.
In this book two renowned experts share their lifelong passion for geodes and their extensive knowledge of world-class geode deposits as they present the latest theories on the formation and occurrence of these amazing mineral gifts of nature.
The most comprehensive book ever written on geodes of the Americas - a definitive reference for serious collectors and a delightful mineral exploration for both experts and novices.
