The Story of Ohio: Geologic and Economic Connections
By Peyton S., Chloe S., Ella S., and Casey L.
Ohio's Geologic Past
Permian Time Period: 299-251 million years ago
Ohio's Southeastern region was a swamp, but over time, the deposited sediment from rivers, sand, and mud, filled it in. Eventually, layers of rock from this period were uplifted, allowing for easier testing. The time period was dated mostly by analyzing these layers consisting of sandstone, shale, coal, and more, instead of the little fossils found from this time period.
Silurian Time Period: 443-416 million years ago
Despite the beginning of this period including a relatively dry climate for Ohio, water soon filled the land. Some of it was shallow and heated easily, but most of the sea covering Ohio was deeper and contained reefs. Later, after some of the shallower seas dried up we were able to extract salt from it.
If you look closely, you can see the imprint of coral!
Ohio's Geologic Past
Ordovician Time Period: 488-443 Million Years Ago
Generally shallow seas covered Ohio in this time period, which meant there was lots of life including horn corals, brachiopods, clams, snails, and more. Rock evidence shows periodic ash layers from nearby volcanic eruptions during this period.
Precambrian Time Period: 4.6-542 Million Years Ago
This time period included continental plate movement and volcanic eruptions. A mountain range formed in the later stages of the Precambrian period, and then weathered over time, producing a hilly landscape.
Where are Ohio's raw materials found?
Did You Know?
Ohio is ranked 4th
in the production of salt
and limestone, and 10th
in the production of coal.
It is also ranked 3rd in the
consumption of coal.
- Salt

- Coal

- Limestone
How do we use these resources today?
In our Homes and Everyday Usage
We use many of these resources in homes today: clay, shale, coal, salt, sandstone, gypsum, limestone, sand, gravel, and petroleum. They are used for parts of the house, outside, inside walls, and even for small little things such as doorknobs! Some examples are: windows are made of sand, silica, aluminum, and petroleum, and driveways are made of petroleum, sand, and gravel. We also use them in many everyday products, such as: soap is made with clay, peanut butter contains salt, and gypsum is included in many cupcakes!
Active vs Inactive Mines
The Rosebud Mining Company produces coal in both Ohio and Pennsylvania. There are three Rosebud mines found in Ohio. The company was founded in 1979 by Clifford Forrest. Some of the largest integrated steel companies in the world purchase from the Rosebud Mining Company.
Dessecker Coal Mine
Rosebud Mining Company
The Dessecker Coal Mine is located in New Philadelphia, Ohio. It was active from 1947 until 1995 and now sits as an inactive mine. Twin brothers Marion and Milton Dessecker ran the mine. From September to May, the brothers would mine coal. After the Federal Coal Mine Health & Safety Act was put into place in 1969, the same year the twins filed for abandonment. Behind locked gated, the Desseckers would continue mining coal until 1995.
