For an introductory college-level physical geology lab class: a review of how to identify common rock-forming minerals. Includes a review of various diagnostic properties, such as cleavage and fractures; hardness; density; color; streak; crystal form; and optical properties such as luster, transparency, and double refraction. Minerals covered include: hornblende, micas (biotite and muscovite), feldspars (plagioclase and potassium feldspars), garnet, olivine, pyroxene, quartz, serpentine, talc, calcite, gypsum, graphite, galena, pyrite, fluorite, halite, hematite, and magnetite. Note: this video indicates over 300 known minerals on Earth; that number is now in the thousands!
**This video comes in the middle of the semester, so there may be terms with which the audience is unfamiliar. For a full playlist, refer to the Geology playlist on the EarthRocks! RU-vid Channel.
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.
