The Paul W. Gast Lecture Series honors mid-career scientists for outstanding contributions to geochemistry.

Carrie Masiello was given the honor of presenting the Paul W. Gast plenary lecture on Wednesday August 21st at the 2019 Goldschmidt Conference in Barcelona, Spain.

Paul Werner Gast (1930-1973)  pioneered the study of rare earth elements from the Earth’s core to its crust.  Gast is credited with leading the development  of rubidium-strontium and uranium-lead radiometric dating methods for all rocks, which was especially important for dating samples from the Moon. His studies of trace elements improved our understanding of the origin of volcanic fluids.
