Conference on "Isotope Tracers in Geochemistry and Geophysics": In honor of Professor Gerald J. Wasserburg on the occasion of his sixtieth birthday

Abstract

On March 23-25, 1987, more than 75 colleagues and former students from ten countries descended on Caltech to honor Professor Gerald (Jerry) J. Wasserburg on the occasion of his sixtieth birthday. Highlighting the three-day activities was a conference entitled "Isotope Tracers in Geochemistry and Geophysics", consisting of contributed research papers, all strongly influenced by an association with Jerry. It was with some nostalgia as well as with an appreciation of their current relevance that we listened to familiar subjects-Precambrian geochronology, radiogenic isotopes as petrogenetic tracers, crust-mantle differentiation, high-resolution ^(40)Ar-^(39)Ar chronology, chemistry of the oceans, rare gases in the atmosphere, isotopic anomalies in meteorites, nuc1eosynthetic components, and cosmochronology. Several talks dealing with terrestrial heat flow, the Antarctic ozone hole, and water solubility in magmas refused to be constrained even by the broad theme of the conference. The encyclopaedic interests of our mentor were made all the more evident by this diversity of scientific questioning.
