Geologist to discuss convergent plate boundary processes

By Matt Brueseke

Robert Stern, professor of geosciences at the University of Texas, Dallas, will give a public lecture "Convergent Plate Margins, Subduction Zones, and Island Arcs" at 4 p.m. Thursday, March 26, in 216 Thompson Hall.

Stern is a 2014-15 Geo PRISMS Distinguished Lecturer, sponsored by the National Science Foundation. He and his students/collaborators use geochemical and isotopic data to address how modern arc crust forms above subductions zones and evolves into true continental crust, how new subduction zones form, and when and why plate tectonics began on Earth.
