Michigan Minerals

Michigan lies at the center of the Great Lakes basin and the diversity of minerals found in Michigan encompasses most of that found in the basin as a whole. Former A. E. Seaman Mineral Museum Curator George Robinson updated and revised the Mineralogy of Michigan by E. W. Heinrich, which was published by the museum in 2004 and is available in the online store.  The book contains 36 pages of discussion of the setting of Michigan minerals only available in the hard copy and an extensive index. The book also lists multiple unidentified mineral species not in the list below.

Provided here are the separate PDF files for each of the different minerals listed in the book as well as a subsequent update when applicable. The references cited in these entries are provided for the alphabetical listing of minerals found in Michigan.
