  189The Mineral Industry of 
Indiana 
This chapter has been prepared under a Memorandum of Understanding between
the 
Bureau of Mines, U.S. Department of the Interior, and the Geological Survey,
Indiana 
Department of Natural Resources, for collecting information on all nonfuel
minerals. 
By James J. Hill' and L. J. Prosser, Jr.2 
The value of Indiana's nonfuel mineral production was $291 million in 1978
and $326 million in 1979. Although value surpassed the $300 million mark
for the first time in 1979, output declined in all commodities except abrasives,
peat, and stone. The following, in decreasing order of value, con- 
tinued as the State's leading commodities: 
Portland cement, crushed stone, and sand and gravel. Clays, gypsum, masonry
cement, dimension stone, and lime were also produced. Imported materials
processed in the State included fluorspar and perlite.
