Petrology Lunch - Mobility of carbonate-rich melts within the deep carbon cycle - Carmen Sanchez-Valle

We are pleased to announce a Petrology Lunch with Carmen Sanchez-Valle on the topic of: Mobility of carbonate-rich melts within the deep carbon cycle.

Abstract:

In this presentation, Carmen will provide an overview of our recent efforts to determine the mobility of carbonate-rich melts in the upper mantle and their associated geodynamic signatures. First, Carmen will illustrate progress in constraining the density and viscosity of carbonate-rich melts under pressure using a combination of synchrotron-based experiments and molecular dynamic simulations. Further, Carmen will introduce a new global density model for multi-component mantle-derived carbonate-rich melts that permits accurate density predictions down to the mantle transition, i.e. 30 GPa, 800 – 2300 K. Finally, Carmen will discuss how the new data and models provide new constrains on the timescales of carbonate melt extraction, the upward migration of carbonate melts and their geodynamic signature within the deep carbon cycle.
