Project Grant 2426074

This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $335,953 to Purdue University to study the geochemical and temporal links between volcanism and plutonism at an ancient subduction zone volcano in Washington. The research team will reconstruct the record of volcanic eruptions and subvolcanic intrusive activity by analyzing the geochemistry, geochronology, and petrology of igneous rocks from the site. The objectives are to determine the timing of magma formation, compositional changes over time, and the depth of magma storage beneath the surface. The project will also produce educational videos and lab exercises to share the research motivation, methods, and findings with the public and high school students. This work will enhance the scientific understanding of subduction zone volcanoes and the hazards they present to nearby populations.
