The Story of Garnet: Tectonics, Water, and Time

Abstract

Garnet is a common mineral in many metamorphic rocks that dazzles with its colors and crystals. It also grows over a wide range of conditions, recording processes of the deep earth spanning millions of years. We will explore how garnet can be used as a history book of those tectonic, petrologic, and geochemical processes, many of which involve the role of fluids in the earth system. Garnet is just one example of how “Every Rock Has a Story,” referring to Ethan Baxter’s YouTube Channel to inspire kids of all ages about the geosciences.
