Description

GEOLOGIC RESOURCES OF MICHIGAN:

A SUMMARY OF HISTORIC PRODUCTION DATA

Peter Voice, Ph.D., Department of Geosciences, WMU

Abstract: The Michigan Geological Survey has generated a summary of historic natural resources production from the mid-1800’s to the present. Production statistics were gathered from historic Michigan and U.S. Geological Survey annual reports and other sources. Production curves and summary data tables were generated.

Commodities considered in the survey include metallic resources (iron, copper, gold, silver), non-metallic minerals (salt, rock gypsum), aggregates (sand, clay, crushed rock, etc.), and energy resources (oil, natural gas, and coal). Significant resources include iron ore (1.5 billion metric tons), copper ore (6 million metric tons), salt (300 million metric tons), gypsum (110 million metric tons), sand and gravel (3.2 billion metric tons) and crushed stone (2.1 billion metric tons). Exploitation of energy resources has generated 1.3 billion barrels of oil, 42 million metric tons of coal and 8 trillion cubic feet of natural gas.

Most commodities harvested in Michigan exhibit similar production curves with increasing production from the 1880’s to the 1970’s. Post-1970 most commodities exhibit declining production. All of the commodities were sensitive to recessions. In 2013 dollars, the estimated value of the historically-produced, geologic resources from Michigan is 560 billion dollars.
