1. Geology of Limestone

Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO3). Formed from the accumulation of marine organisms, limestone is often found in areas that were once underwater. The geological formations in Ohio consist of various limestone deposits, some dating back over 400 million years. The most significant limestone formations in Ohio are the Cincinnati and the Ohio Shale, which provide a rich source of this valuable mineral.

The Importance of Limestone

Limestone is essential for several reasons, including:

• Construction Material: Used in buildings, roads, and bridges.
• Agricultural Lime: Improves soil quality and pH balance.
• Industrial Uses: Raw material for cement, glass, and steel production.
