Mark Stelten has conducted research on magmatic systems since 2008 with an emphasis on geochronology and geochemistry. He has worked on a variety of volcanic and plutonic systems over the course of his career. Prior to working with the U.S. Geological Survey, he conducted research on the Tuolumne Intrusive Suite in Yosemite National Park, the South Sister volcano in Oregon and the Yellowstone Plateau Volcanic Field in Wyoming.
