Ohio's geology is rich with source materials used in numerous industries and in making a variety of everyday products. A robust history of industrial minerals extraction has driven the state's economy since before statehood in 1803. Today, Ohio continues to be a leading producer nationally of several commodities, including limestone, dolomite, sandstone, and conglomerate; sand and gravel; clay and shale; and salt.
The ODNR Division of Geological Survey compiles production and economic data, submitted by the state's industrial mineral operators, to produce the annual Report on Ohio Mineral Industries. The report is available as a free download and includes a map of active operators.
