DOWNLOAD EBOOKOver 140 color photos, diagrams, and text reveal the crystal structures, habits, names, and changing family relationships of silicate crystals. This thorough guide provides an introduction to crystallography, the current classification of silicate structures, and reviews orthosilicates, disilicates, chain silicates, sheet silicates, and framework silicates. Explore different ways the silicate tetrahedron can be arranged and great diversity of structures that result. Crystal structure is presented with drawings of ideal crystal forms and photographs of real crystals. In this way, mineral collectors can better understand the interplay between atomic arrangements and external habits, and ultimately develop an eye for recognizing crystal symmetry. This book is a must for all serious collectors of minerals.

DOWNLOAD EBOOKWith the tremendous growth of population in this and neighboring states, there are more collectors than ever before and with the rapidly escalating prices for mineral and fossil specimens in the retail market, there is a great demand for displayable material. It has become necessary for professional geologists, hobby collectors, and commercial collectors to recognize each others existence and to try to work together within a framework of regulation, courtesy, and common sense so that material of scientific value is not lost and undue restrictions are not placed upon collecting. There is a continuing need for collectors and professionals to work together with resource managers and legislators to develop workable laws and rules affecting the collecting of minerals and fossils. This publication contains details information about collecting areas, divided by county to make for ease of use. Each collecting area contains information about the minerals, rocks, or fossils present, map recommendations, and other helpful tips on getting to the sites.

DOWNLOAD EBOOKThe definitive resource for mineral collectors, this comprehensive book describes the structural relationships among orthosilicateminerals, known for their hardness and brilliant colors, and the geological conditions that create prized specimens. It is illustrated with nearly 500 structure diagrams, color photos, and electron micrographs that will help collectors appreciate the minerals already in their collection, build a collection with greater depth, and find additional information. A web link allows readers to view the crystal structuresin three dimensions for a richer appreciation of their details, and an extensive bibliography includes easily accessible references ranging from foundational literature to reports on current scientific research.
