This volume is historically the fifth and most comprehensive catalogue of South Australian minerals yet prepared, and is based on work begun by the South Australian Department of Mines in 1956. For descriptive convenience, the State has been areally divided into fourteen regions: these regions (if relevant) are arranged alphabetically for each mineral species included in the catalogue, and known localities are grouped under the particular region. A set of regional maps, which act as a guide to the location of prominent mineral occurrences, has been provided. More detailed maps are readily available from State and Commonwealth mapping authorities. The Mineralogical Record - published, 1980 edition of M. Fleischer's Glossary of Mineral Species, has been used as the controlling reference on formal mineral names and compositions given collectively to specimen descriptions presented.
