A Short Reflection on Books

Most books on minerals are field guides and "picture books". They can help to identify your specimen and to learn something about their properties, but they don't get you anywhere beyond that. I strongly recommend to get and read textbooks on geology and mineralogy. They don't sort minerals just by their color, but deal with the topic systematically. First they look very boring and it needs some discipline for a layman to work through them. But once you've read a few chapters, you will note that slowly something of a "big picture" is about to emerge.


Recommended Books

I'd like to recommend a few books that I found worth reading. In accordance with what I've written above, some of them are textbooks on geology, and only a few deal specifically with quartz.

  • Physical Geology, by Brian J. Skinner and Stephen C. Porter
    A well written introductory textbook on physical geology with lots of figures.

  • The Solid Earth - An Introduction to Global Geophysics, by C.M.R. Fowler
    This book has nothing to do with quartz but is about the inner workings of the planet earth, and it clearly addresses expert readers and undergraduate students of geology. However, I had more than one aha experience when reading it, so for those of you who "want to know", it is listed.

  • Minerals - Their Constitution and Origin, by Hans-Rudolph Wenk and Andrei Bulakh
    A nice introduction to mineralogy. Different from most textbooks on mineralogy (that simply count off minerals following to the Dana or Strunz system), it introduces minerals and mineral groups in the context of geological environments.

  • Minerale und Gesteine - Eigenschaften - Bildung - Entstehung, by Gregor Markl
    This book is a very nice introduction into petrology and its methods and is mentioned because it is a very notable exception from German scientific literature: it has been written with the reader in mind.

  • The System of Mineralogy of J.D. Dana. III. Silica Minerals, by Clifford Frondel
    The first comprehensive and still best English monography on silica minerals.

  • Quarz-Monographie
    - Die Eigenheiten von Bergkristall, Rauchquarz, Amethyst, Chalcedon, Achat, Opal und anderen Varietäten
    , by Rudolf Rykart.
    From the collector's point of view, still "The Book" on quartz, in particular when it comes to crystal morphology. As far as I know, there is no recent English quartz monography that is a match for it. The book has unfortunately not yet been translated from German.

  • Silica - Physical behavior, geochemistry and materials applications, by P.J. Heaney, C.T. Prewitt and G.V. Gibbs (Editors).
    Reviews in Mineralogy, Vol.29
    Mineralogical Society of America, 1994
    ISBN 0-939950-35-9
    This is a collection of reviews on silica structures and properties, including those of quartz, by various authors. The articles are referenced individually in the text of these web pages and are accordingly listed under "Articles". The book can be regarded as a scientific publication.
