For a college-level introductory course in physical geology: An overview 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 degree of metamorphism to which the rock has been subjected. Reviews how to identify each of the following rocks, including what the rock was (parent rock) and what the metamorphic setting was in which each rock formed: marble, quartzite, hornfels, skarn, migmatite, gneiss, schist, phyllite, slate, serpentinite, eclogite, and greenstone.

**This video comes towards the middle of the semester, so some terms may not be familiar to the audience. In fact, it is recommended that you only watch this video AFTER you have watched Identifying Minerals, Identifying Igneous Rocks, and Identifying Sedimentary Rocks. This video goes over ALL of these rock types and explains how they transform into new metamorphic rock. It can be daunting if you start with this video.

The content of 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.
