The mdMELTS project is a far reaching vision of extending MELTS modeling capabilities down to the base of the Earth's lower mantle. While the "x" in xMELTS stands for extreme, the "md" in mdMELTS stands for molecular dynamics (MD). This project is being undertaken by Ghiorso (at OFM Research Inc.) and Frank Spera (at UC Santa Barbara) and is as yet unfunded. The idea is to extend the silicate liquid equation of state calibration to very high pressure (and temperature) utilizing MD computer simulations of liquids. This will allow liquid-solid phase equilibria to be modeled at high pressure. Our preliminary work on this project is focusing on the system MgO-SiO2. As results and models become available, they will be posted to this web site.
