Center for Isotope Geochemistry

The Center for Isotope Geochemistry (CIG) is a joint-institution research center, with labs both at LBNL and UC Berkeley. This state-of-the-art analytical facility was established in 1988 to measure the concentrations and isotopic compositions of elements in rocks, minerals, and fluids in the earth’s crust, atmosphere, and oceans. CIG has a community of roughly 25 people—scientists, research lab staff, postdoctoral researchers, graduate students, and administrative/computer support staff. It is directed by Donald J. DePaolo, (Associate Lab Director of Energy & Environmental Sciences) at Lawrence Berkeley National Lab, and Class of 1951 Professor of Geochemistry, Department of Earth and Planetary Science, UC Berkeley.

These facilities provide state-of-the-art characterization of all types of earth materials for research. The instrumentation and laboratories are integral to CIG's focus on developing new isotopic ratio methods to study fundamental earth processes, and environmental and energy problems of national interest.
