Available in PDF, EPUB and Kindle. Book excerpt: Catalogues of the minerals found in Tasmania have been kept since almost the earliest days of mining and have been of invaluable assistance to prospectors, mineral explorers, mineralogists and collectors. This catalogue was first published by the Tasmania Department of Mines in 1910, and was extensively revised in 1969. Since then the improvements in technology and further investigations of minerals and mineral deposits have not only increased the number of identified species and data on mineral occurrences, but have also invalidated many previous 'species'. This catalogue extensively updates the previous catalogue. A total of 753 minerals are described, comprising 483 confirmed species, 162 unconfirmed species, 72 variety or invalid names, and 36 series and group names. All entries in the 1969 catalogue have been re-evaluated and are now reclassified as to their known or likely validity. Species invalidated or doubted from the 1969 listing have been retained, with comments.
