Is there Oxygen in the Earth’s outer core
Project headed by Professor Dave Walker of the Lamont-Doherty Earth Observatory of Columbia University, New York, USA
Use energy dispersive X-ray diffraction; and high pressure / high temperature phase transitions to help determine the volume of Oxygen at high pressure and temperature (~550°C and 2 to 9 GPa). Then see if the volume this has interesting implications for Oxygen being involved in the Earth’s Outer Core
