Jessica Warren - Geography

Jessica Warren

Assistant Professor | Department of Geological Sciences

New research from Jessica Warren, a geologist in UD's College of Earth, Ocean, and Environment, and her colleagues has resolved 40 years of debate on the strength of olivine, the most abundant mineral in the Earth's mantle. 

Warren and researchers at Stanford University, Oxford University and University of Pennsylvania have published their findings in the American Association for the Advancement of Science journal Science Advances. 

“Measuring the strength of olivine is critical to understanding how strong tectonic plates are, which, in turn, matters to how plates break and create subduction zones like those along the Cascadia plate, which runs down the west coast of Canada to the west coast of the United States,” Warren said. It’s also important for understanding how plates move around over the million-year time scales.
