Rocks and Minerals of Ohio

While the Native bedrock of Ohio is primarily sedimentary, mainly limestone, sandstone and dolomite, many other igneous and metamorphic rocks can be found all over Ohio because glaciers brought them down from Canada. This live-action video looks at the principle rock types found across Ohio and where they might be found. It also examines the classification, origin, and economic importance of these rocks. Excellent introduction to the study of mineralology.
