Energy-dispersive X-ray powder diffraction spectra have been collected for aragonite (CaCOr) and dolomite [CaMg(COr)r] at high pressure and high temperature, using synchrotron radiation and a cubic multi-anvil apparatus. Unit-cell volumes were measured up to 7 GPa and 1073 K along several isothermal paths. This study has confirmed previously determined but still debated values of the bulk incompressibilities at 298 K t65.4(5) GPa for aragonite and 90.7(7) GPa for dolomitel and thermal… CONTINUE READING
