It is an honor to introduce Peter Ulmer, one of the winners of the 2022 Norman L. Bowen Award of the AGU Volcanology, Geochemistry, and Petrology section. Peter’s breadth of approaches spans experimental petrology, field geology, and magma rheolog...

Mike Walter is an experimental petrologist who, like Bowen, asks major questions about Earth. His career began with the resolution of a large number of questions surrounding the compositions of melts and residue produced during partial melting of ...

Graham Pearson merits the 2019 Norman L. Bowen Award for adding to our fundamental understanding of igneous processes in the upper mantle through studies of volcanic rocks, exhumed mantle sections, subcontinental mantle samples, and diamonds and thei...

Mary Reid is receiving the Bowen Award for her creative and innovative application of zircon geochronology for understanding active silicic magma systems. Her 1997 paper in Earth and Planetary Science Letters, “Prolonged residence times for the...

At a time when many of us focus on models of multidimensional chemical systems, pursue the first measurements of new isotope systems, analyze ever smaller samples, or write short, “silver-bullet” papers, Craig Manning brings exceptional r...

Bernard Marty has made major contributions to our understanding of the origins of volatile elements in the terrestrial planets. One could perhaps highlight four areas, centered on neon, carbon, nitrogen, and xenon. In parallel with Sarda and others, ...

The Bowen Award is presented to Dante Canil in recognition of his seminal work on the history of the oxygen fugacity of the upper mantle. By the early 1990’s Fe3+/Fe2+ measurements of peridotites and MORB glasses indicated that the modern suboc...
