Ohio's most important resources are fertile soils, and valuable mineral deposits such as coal, oil, natural gas, and rock salts.
The mineral composition and texture of the rock are most important in determining how a rock was formed. These factors provide clues about the conditions under which the rock formed, such as temperature, pressure, and the presence of fluids. By analyzing these characteristics, geologists can infer the rock's origin and history.
Carbonates are the second most important mineral group.

Quartz
The most common rock forming mineral groups would be: silicates, carbonates, sulfates, sulfides, halides, and oxides.
The most common mineral found in rocks is quartz. Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, making it abundant in the Earth's crust.
a rock called Magnetite. :3
mineral oil
Mineral texture provides clues as to the origin of the rock particles and the processes which lead to the rock's formation. Texture would include the size and arrangement of the mineral crystals or particles found in the body of a rock.
