Geologic History of Ohio
During the Mississippian period, dark organic muds gave way to fluvial and deltaicsilts and sands.
Marine seas gradually flooded the land surface and covered ohio by late cambrian period depositing silt mud and limy muds
Some of the rocks that were formed were conglomerate, sandstone, shale, clay, limestone, coal, and flint.
The swamp had reduced and most of Ohio became a coastal plain. The swamp was made of deltaic sand and mud.
Eastern Ohio was a big swamp.
Sandstone, coal, and limestone were formed in this period.
Where Are Raw Materials in Ohio Coming From?!
In addition to coal and refined petroleum, Ohio produces much quantities of salt, most of it comes from large rock salt mines. The remainder salt comes from brine. Limestone and dolomite are also highly useful products of the state's mining industry, followed by sand and gravel.

How are rocks and minerals used today?
Rocks and minerals are widely used today. They serve many purposes and help us accomplish many things. Ohio has produced mass amounts of minerals for more than 200 years. Coal, limestone, sandstone, clay, iron, steel, are materials that have helped build cities and monuments. Coal is one of the most valued types of rock that we use in Ohio. It contributes to generating electricity, and producing things like shampoo, paints, insulation, explosives, and fuel gas for cars. Ohio is 10th in coal production, 4th in limestone production, 3rd in sandstone production, 6th in sand and gravel production, 5th in clay and shale production, and 4th in salt production. Ohio plays a crucial role in mineral and rock production throughout the nation.
