Observe an animation of metamorphic rocks forming

Matthew Nyman, Lenni Armstrong, Exploring Earth

The Flash animation shows the evolution of granitic igneous rock to a metamorphic rock focusing on changes in alignment of amphibole, plagioclase feldspar, and quartz crystals. An inset provides a close up of how pressure compresses mineral grains and forms new minerals. The animation can be paused and rewound to stress important points.
