William McDonough vs Terry Plank

William McDonough is a geologist and geochemist who has significantly advanced our understanding of Earth's composition and structure. He developed the widely accepted compositional model of the silicate Earth that describes the chemical makeup of Earth's crust and mantle. His research focuses on using the abundances of elements, particularly refractory lithophile elements, to constrain Earth's bu...

Terry Plank is a geochemist and professor at Columbia University who specializes in studying the volatile contents of magmas at subduction zones. Her research utilizes mineral inclusions preserved in volcanic crystals to reconstruct the concentrations of water and other elements in arc magmas. Plank has conducted field research at numerous subduction zone volcanoes worldwide, including those in Ce...
