During the early stages of Earth's formation, a massive ocean of molten rock known as a 'magma ocean' blanketed the planet's surface and penetrated deep into its core. The cooling rate of this 'magma ocean' played a crucial role in shaping the layered structure of the Earth and determining the chemi

“This magma ocean has been an important part of Earth’s history, and this study helps us answer some fundamental questions about the planet,” said Mainak Mookherjee, an associate professor of geology in the Department of Earth, Ocean, and Atmospheric Science. To overcome those limitations, Mookherjee and collaborators ran their simulation for up to six months in the high-performance computing facility at FSU as well as at a National Science Foundation computing facility. This eliminated much of the statistical uncertainties in previous work.
