Paul W. Gast Lecture

The Paul W. Gast Lecture Series honors the Geochemical Society's first Goldschmidt Medalist. The lecture is awarded to a mid-career scientist for outstanding contributions to geochemistry. The lecture is presented as a plenary at the Goldschmidt Conference and includes a certificate and an honorarium (1000 Euro)

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