Phase relations of CaCO 3 at high pressure and high temperature

Phase transitions in calcite, a naturally occurring crystalline form of CaCO 3 , have been investigated by three different experimental techniques: (1) in-situ X-ray diffraction (XRD) using synchrotron radiation to 6 GPa and 1750 °C in a cubic anvil press; (2) Raman scattering to 10 GPa at room temp...
