Mineralogy of Arizona / Минералогия Аризоны

Many new mineral species have been documented in Arizona since the third edition of Mineralogy of Arizona was published in 1995. This new edition adds to the extensive work of the previous authors, who built the foundation on which this new effort rests. This edition is dedicated to these men: John Anthony, Sidney Williams, and Richard Bideaux.The field of mineralogy has undergone many changes since the third edition. Mineralogical nomenclature has changed, and now some species have been relegated to group names (e.g., monazite group); others have had element designations added, as in euxenite-(Y); and still others have been discredited for various reasons. The new analytical equipment available today has made it possible to more easily subdivide previous valid species, often based on the major element present. This is illustrated by the zeolite minerals, where chabazite is now a group name with five species who differ only in the major element present: Ca, K, Mg, Na, or Sr. Older references are unaware of the new nomenclature, and many occurrences are noted where the specific species as now defined is not presently known. This new edition lists a total of 992 valid mineral species in Arizona, which is an increase of 182 species compared with
the third edition. Several mineral species found in the third edition have been discredited and are no longer found in the occurrences section. Many are discussed in some detail in appendix E. Fifty-one minerals were removed from the third edition because they were either discredited as a mineral species by the International Mineralogical Association (IMA), changed to a group name, or renamed by changes in nomenclature as mineral groups and relationships were redefined <...>
