The Science & Society Distinguished Public Talks Series presents, "The Discovery and Significance of Diamonds from The Alps," a talk by Jane Selverstone on Thursday, Nov. 17 at 5 p.m. A meet and greet will also be held beginning at 4:30 p.m. The lecture, which is free and open to the public, will be held in room C at the University of New Mexico Conference Center, located at 1634 University Blvd., NE. Plenty of free parking is available.

Selverstone and her colleagues discovered metamorphic diamonds In the Italian Alps in 2010. The diamonds were discovered in oceanic rocks that were subducted to a depth of approximately 140 kilometers and then brought back to Earth's surface along faults. The diamonds are the first ones to be found in the Alps and are also the first metamorphic diamonds to be found in rocks of clear oceanic origin. The diamonds occur in and are associated with fluid inclusions that were trapped during subduction. As a result, they provide researchers with direct information on mechanisms of fluid-mediated carbon transfer at depth in the Earth. Selverstone will provide an overview of Alpine geology, describe the discovery of the diamonds and discuss the implications for carbon cycling at convergent plate boundaries

Selverstone is a research professor in UNM's Department of Earth and Planetary Sciences. She is a Fellow of both the Geological Society of America and the Mineralogical Society of America, and has been highly lauded for both her research and teaching. In 2007, Selverstone was named the Outstanding Teacher of the Year at UNM.

Her research includes the application of petrologic and geochemical techniques to interpretation of tectonic processes; determination of pressure-temperature-time-deformation paths; relationships between fluid-rock interaction and deformation; feedback effects between metamorphic reactions and deformation mechanisms; the use of mantle and crustal xenoliths to document lithospheric evolution; and chlorine stable isotope geochemistry.

Science & Society Distinguished Public Talks are co-sponsored by the Albuquerque section of the Institute of Electrical & Electronic Engineers (IEEE) and its Life Members Affinity Group, Sigma Xi (the Scientific Research Society), the Department of Physics & Astronomy, the College of Arts & Sciences, the University Honors Program, and the Division of Continuing Education.
