Geology, Geochemistry & Geophysics

The study of the solid Earth and the oceans, and the processes that shape them, is fundamental to understanding the Earth & Environment as an evolving system.  The Earth holds natural resources that are vital to modern civilization, and it creates natural hazards that affect our lives.  The solid earth interacts with the hydrosphere, atmosphere, and biosphere through myriad geological processes including tectonics, volcanism, weathering, and erosion.  We study both modern and ancient processes and conditions through the lens of geological, geochemical, and geophysical observations at field sites around the globe and in our laboratories.  Research in this broad field explores the geologic record of 4.5 billion years of Earth evolution from the deep mantle to the surface, and encompasses phenomena ranging from earthquakes and volcanic eruptions to the slow erosion of mountains and coastlines, and structures ranging in size from individual mineral grains to entire planets.
