Hey's Chemical Index of Minerals

All CIM references are taken from the THIRD EDITION of Hey's Mineral Index, by A. Clark, Dept. of Mineralogy, Natural History Museum, London.

Book Information: 852 pages. hard cover. Published by Chapman & Hall, London 1993.

Hey's Mineral Index groups all minerals into one of 32 groups based on their chemistry - allows you to search for minerals using these groupings.

Click below to view subgroups or minerals in each of Hey's groups.

Primary Groups
