Description:

We will begin with a review of what minerals are inferred to be in the core and what minerals are inferred to be in the mantle. Students will then sketch what they think the core-mantle boundary looks like. Students will make observations of samples of pallasite (identify texture and compositions). Next using phase diagrams (e.g., Fe, olivine, post-perovskite) determine the temperatures and pressures at which these minerals might be stable at the core-mantle boundary. What is the coordination number for these inferred phases at this boundary? Are the phases liquid, solid or both? Next assess and describe how P and S wave velocities change at the core-mantle boundary.
