JAMES DWIGH DANA

First published in 1837, Dana's System of Mineralogy has remained the definitive reference on descriptive mineralogy for over 150 years and seven editions. Now, for the first time in half a century, comes a new edition of this undisputed classic—comprehensive, up to date, and More...ready to take mineralogy into the twenty-first century. Dana's New Mineralogy, Eighth Edition describes, catalogs, and classifies the more than 3,000 mineral species currently recognized. Completely rewritten from the seventh edition, the material emphasizes mineral structure and is generously supplemented with unique, specially commissioned structural diagrams. Coverage is carefully balanced, from substantial essays on important species such as calcite and groups such as the feldspars to more compact descriptions of rare minerals. Silicate minerals have been included for the first time, and are classified into homologous groups sharing a similar structure. Entries identify minerals by Dana classification number, name, and chemical formula. Descriptions contain crystallographic data and information on morphology, physical properties, composition, and relationships with other minerals. The Eighth Edition also boasts extensive data on the locations of minerals worldwide, and offers instant access to the primary literature of the past half-century—including often difficult to locate sources from Eastern Europe and China. Extensive indexing makes it easy to find minerals based on proper, variant, regional, or common names. Years in the making, Dana's New Mineralogy, Eighth Edition has been worth the wait. It will continue to be the chosen reference companion of mineralogists, mineral collectors, gemologists, and geologists, as well as chemists, physicists, and amateur enthusiasts of every description. Dana's New Mineralogy classifies and describes the more than 3,000 mineral species currently recognized. Completely rewritten to keep pace with developments in mineralogy today, this Eighth Edition remains unrivaled as the definitive reference on the subject for professionals, students, and interested readers of every background.
