Paperback : £13.57
Step-by-step Questions and Answers with detailed colour photographs for easy identification. The Firefly Guide to Minerals, Rocks and Gems is designed for easy and reliable identification of minerals, gems and rocks. The identification process begins with the stone's streak colour, which is how the book is organised: Blue, Red, Yellow, Brown, Green Black and White. Using a sequence of straightforward questions and answers - aided by over 1,000 photographs and drawings -- the book narrows down the possibilities among 350 minerals, gems and rocks to reach the conclusive classification. Identification is then further narrowed down with respect to Crystal form, Hardness, Luster, Density, Cleavage, Break and Tenacity. Each rock's main photograph shows the general or typical view, and identification tips about features are noted in the margins of the respective page. Similar stones are presented for comparison and tips are provided that can eliminate imposters. Drawings show the mineral's crystal shape. The chemical formula reveals the elements from which the mineral is composed. There is also information about where the stone is typically found and some of the ways that humans have utilised it. Packed with beautiful photographs of earth's many rocks, minerals and gems, The Firefly Guide to Minerals, Rocks and Gems is perfect for amateur mineralogists and collectors. AUTHOR: Rupert Hochleitner has a PhD in Mineralogy. His area of specialisation is systematic mineralogy. Other research areas are meteorites, in particular those of the planet Mars, oxidation minerals, and pegmatitic phosphate minerals. He has published numerous scientific articles and was for a long time editor-in-chief of the journal LAPIS, a specialist magazine for mineral collectors and mineral lovers. Since 1993, he has been deputy director of the Mineralogical State Collection Munich. 1043 colour and 257 b/w photographs

A scholarly survey of mineralogy, this manual will appeal to the
serious specimen collector with its stunning photos and erudite
detailing. A color chart in the fold-out cover divides sections
into blue, red, yellow, brown, green, black, and white rocks. A
matching back cover categorizes and diagrams 28 crystalline forms.
Each entry identifies the mineral by chemical formula and lists
succinct details of cleavage, hardness, luster, density, fracture,
and tenacity. Some contain common names (fool's gold, desert rose).
Descriptors specify types -- vitreous, aggregate, metamorphic,
igneous, radial -- and catalogue geometric shapes with such terms
as isometric, monoclinic, tetragonal, rhombic. Commentary links
minerals with geological formation in Alpinetype fissures,
sedimentary rock, and hydrothermal veins and identifies some
locales, such as Iceland, the Canary Islands, and Silverberg in the
Bavarian Forest. A knowledgeable historian as well as mineralogist,
Hochleitner notes anecdotal particulars; for example, the fact that
Goethe was a rock hound, aegirite bears the name of the Nordic sea
god, and copper working began in the Stone Age. A book for serious
students of geology and earth elements, this work comes highly
recommended for public, high-school, and college libraries.--Mary

Hochleitner's pocket-size field guide is detailed and precise.
Arranged by streak color, it includes abundant, details photos of
specimens in naturel states and, often, close-ups after cutting or
polishing, as well as key features for identification. Brief
descriptions and information on chemical composition, crystal
structure, and location aid in usefulness. Consider for all
libraries when updating earth sciences or mineralogy sections.--

Packed with beautiful photographs of earth's many rocks, minerals
and gems... An ideal instructional reference for geology students,
amateur mineralogists and collectors alike -- making it
unreservedly recommended for personal, professional, community, and
academic library collections.-- "Midwest Book Review" (12/1/2019

The Firefly Guide to Minerals, Rocks and Gems is a field guide
designed for quick and easy identification, and appears in a
compact paperback take-along tote format that lends to this use.
Photos of rocks and gems are accompanied by notes on crystal forms,
hardness, density, and more. Each photo captures both typical views
and close-ups of the rock's shape in comparison to others which may
be closely related. This eliminates many problematic identification
obstacles, making The Firefly Guide to Minerals, Rocks and Gems an
essential reference for rock hounds actively working in the
field.--Diane Donovan "Donovan's Literary Services" (12/1/2019
