Phase Diagram with Depth as Modeled with the ExoPlex Mass-Radius-Composition Calculator

Caption

This is a slice through a model composition of TRAPPIST-1 'f' which contains over 50 percent water by mass. The pressure of the water alone is enough to cause it to become high-pressure ice. The pressure at the water-mantle boundary is so great that no upper mantle is present at all; instead the shallowest rocks would be more like those seen in the Earth's lower mantle.
