Garvin begins with a brief treatment of the origins of Iowa's minerals, moving from the oldest -- with ages well in excess of a billion years -- to those most recently formed. He describes the state's major mineral occurrences, providing detailed information for both specialists and amateurs, including how to obtain access to collecting sites. A history of Iowa's mineral industries complements Garvin's more technical information; this history is supplemented with stories about the Cardiff Giant (who now has his own web page), Ottumwa's Coal Palace, and the meteor falls of the nineteenth century. Sixteen striking color photos showcase the finest of Iowa mineral specimens.
The minerals that occur most abundantly in Iowa make up the sandstone, shale, limestone, and dolostone bedrock strata and the soils and alluvium that blanket them. Readers of Iowa's Minerals will come away with a greater awareness and appreciation of Iowa's generous mineral endowment.
