Cation disorder in dolomite, CaMg (CO

The structure of dolomite, CaMg(CO 3) 2, was determined from 298 to 1466 K at a constant pressure of about 3 GPa using in situ synchrotron X-ray diffraction data to investigate the state of disorder.An order parameter s, defined as 2 x Ca − 1, varies from s = 1 (where x Ca = 1) for a completely ordered dolomite to s = 0 (where x Ca = 0.5) for a …
