Conglomerate is similar in structure and appearance to sandstone. However, the grains of quartz and rock debris are larger than sand particles.

In Ohio this kind of sedimentary rock also is of Late Paleozoic age, and occurs mainly in the eastern half of the state.

As with sandstone, conglomerate is one of Ohio’s industrial rocks.
