Dr Tanya Furman Looks Deep Into the Mantle

  • Jan 12, 2019

Our featured speaker this week is Dr. Tanya Furman, Penn State University.

"Drip magmatism and the instability of the subcontinental lithospheric mantle: Evidence from Saudi Arabian basalts"

Post-Miocene basaltic volcanism in the Middle East takes place in a complex tectonic setting with adjacent areas of subduction, rifting and transform motion. These plate interactions apparently destabilize the lower lithosphere, leading to eruption of mafic lavas with distinctive geochemical and mineralogical features. Simply put, these basalts have some of the most interesting textures that you will ever see because they capture the juxtaposition of processes occurring at both long (millions of years) and short (days) timescales. This talk presents an integrated picture of the origin of mafic volcanism through the interplay of metasomatism and lithospheric melting, drawing upon geochemical characteristics of the lavas and their crystal cargo.

Join us for this deep dive on Friday, January 18, 2019 at 12:30 PM in Room 204, Natural Science Building on the East Lansing campus.
