This site contains 15 time-lapse QuickTime movies that show the experimental deformation behavior of octachloropropane. This compound shows similar microstructures to those found in quartzite, and thus is a nice analog for the deformation of rocks. The movies illustrate cataclastic deformation, grain boundary opening, formation of subgrains, subgrain boundary formation and grain boundary migration, ribbon formation, grain growth at zero strain rate, and grain boundary migration during high temperature deformation.
Part of the Cutting Edge collection. The NAGT/DLESE On the Cutting Edge project helps geoscience faculty stay up-to-date with both geoscience research and teaching methods.
