About the P.W. Gast Lecture

This award is bestowed jointly by the EAG and the Geochemical Society and has been named in honor of Paul W. Gast, the first Goldschmidt medallist (the Goldschmidt award is bestowed by the Geochemical Society). This lectureship is awarded to a mid-career scientist for outstanding contributions to geochemistry. The lecture is presented as a plenary at the Goldschmidt Conference.

The selection of the lecturer alternates between the GS Board of Directors and the EAG Council depending on the location of the Goldschmidt Conference.

To be eligible, nominees must have received their PhD at least 10 years and no more than 25 years of full time equivalent research employ before the Goldschmidt conference at which the lecture is presented.
Nominations of underrepresented groups are encouraged.

We are committed to promoting the diversity of our awardees, to recognizing a wide range of different types of exceptional contribution, and we acknowledge the different career paths that lead to the achievement of such contributions.

The award is presented annually at the Goldschmidt Conference and consists in a certificate and an honorarium (1000 Euros).

About Paul W. Gast

Paul W. Gast (1930-1973)

During his career, Paul W. Gast pioneered the study of rare earth elements in examining the crust, mantle, and interior of the planet. He led the development of the use of rubidium-strontium and uranium-lead radiometric dating methods for rocks, particularly for samples returned from the Moon. His examinations of trace elements resulted in new understands of how volcanic fluids originate. Gast was the first recipient of the V.M. Goldschmidt Award.
