Abstract

Structural parameters have been refined using X-ray intensity data for a stoichiometric dolomite single crystal at room pressure and at 1.50, 2.90, 3.70, and 4.69 GPa; and for a single crystal of a ferroan dolomite with approximately 70 mol% CaFe(CO₃)₂ at room pressure and at 1.90, 2.97, and 4.0 GPa. The principal structural change with increasing pressure is compression of the CaO₆ and (Mg,Fe)O₆ octahedra. In addition to displaying similar axial compressibilities, dolomite and ankerite display similar bond compressibilities and bulk moduli. No phase change was observed in either compound throughout the pressure range studied. -from Authors
