John W. Valley received the Bowen Award, presented by the Volcanology, Geochemistry, and Petrology Section at the 2003 Fall Meeting in San Francisco, California, last December. Jim O'Neil and I are particularly pleased to present Professor John Valley, of the University of Wisconsin, for this year's Bowen Award. We have known John for about 25 years, first as a graduate student, and now as colleague and good friend. We nominated him in recognition of his recent work on zircons from early Archean rocks of northwestern Australia, which provides documentation of previously missing Earth history with evidence for an early ocean and a relatively cool history during the Hadean Eon. John has also published a major review on oxygen isotope variations of magmatic zircons preserved through geologic time, as a result of which he proclaims that zircons are forever. |
