Identifying Metamorphic Rocks -- Earth Rocks!

For an introductory college-level physical geology class: a review of how to classify and identify a metamorphic rock. Includes a discussion of foliation and other clues to look for in a rock to indicate the intensity or grade of metamorphism to which the rock was subjected. Reviews how to identify each of the following rocks, including what the rock used to be (parent rock) and what was the metamorphic setting in which each rock formed: marble, quartzite, hornfels, skarn, migmatite, gneiss, schist, phyllite, slate, serpentinite, eclogite, and greenstone. **This video comes near the middle of the semester, so there may be terms with which the audience is unfamiliar. In fact, it is recommended that you watch this video only AFTER watching Identifying Minerals, Identifying Igneous Rocks, and Identifying Sedimentary Rocks. This video reviews ALL those rock types and discusses how they transform into a new metamorphic rock. It can be overwhelming if you start first with this video.

Content within this video is based on information available in any standard introductory college geology textbook (or lab manual), such as Essentials of Geology -- Tarbuck and Lutgens -- Pearson Publishing.
