When continents split and a new ocean forms, large volcanic eruptions can occur. These eruptions create thick layers of lava mixed with sediment known as seaward dipping reflectors (SDRs). These features are common along continental margins and can host large mineral deposits. But, the mechanisms that generate the large volumes of magma for SDRs remain unclear. Hotspot mantle plumes from deep within the Earth are often invoked as the source of this magma. An alternative hypothesis is that formation of SDRs involves the continental lithosphere. This study focuses on East Greenland, a unique place where both igneous dikes onshore and offshore SDRs occur. The study will compare the geochemistry of these two features to trace the origin of the magma. New computer models using the geochemical results will show how continental lithosphere contributes to magma production during rifting. Findings will be integrated into a new course on the Energy Transition, helping students connect Earth Science with technology. The project also supports undergraduate and graduate researchers in geochemistry. Students develop Earth Science skills relevant to the challenges of the 21st century economy. This project will strengthen Michigan State University’s analytical geochemistry lab, a key resource for scientific and industrial partners in the Great Lakes region. This project is co-funded by the Marine Geology and Geophysics and Chemical Evolution of the Solid Earth and Volcanology Programs. Wh
