Geochemistry

The Geochemistry faculty study a wide range of processes and interactions, including products of large-scale Earth differentiation, such as the composition, evolution and age of the mantle and core, the formation and evolution of oceanic and continental crust, interactions between the geochemical environment (soil, water, air) and human health, fundamental questions involving the oceans and continental water systems, global geochemical cycles involving the atmosphere, oceans and Earth's interior, natural and engineered methods for carbon capture and storage, and using a wide range of geochemical archives to understand how and why the ocean and climate have changed at timescales ranging from seasons to millions of years. The faculty has developed strong collaborations with Columbia University engineers, biologists, public health researchers and American Museum of Natural History petrologists, planetary geologists and paleontologists.
