What lies beneath the ice? Using the geochemistry and geochronology of modern river cobbles to better decipher the evolution of a glaciated volcanic arc (Wrangell Arc, Alaska, U.S.A.)

What lies beneath the ice? Using the geochemistry and geochronology of modern river cobbles to better decipher the evolution of a glaciated volcanic arc (Wrangell Arc, Alaska, U.S.A.)

The ~30 Ma to Recent Wrangell Arc (WA), Alaska is an ideal location to study subduction and slab-edge magmatism. However, the WA covers a huge area (~15,000 km2) and ~29% of the WA is covered by glaciers with rugged topography, making bedrock sampling challenging. We addressed these barriers with ge...
