The structure and isothermal equation of state of aragonite were determined to 40 GPa using synchrotron single-crystal X-ray techniques. In addition, powder diffraction techniques were used to determine thermal expansion between 298–673 K. At room

The rare evaporite minerals hanksite, Na22K(SO4) 9(CO3)2Cl, and tychite, Na6Mg 2(CO3)4(SO4), are excellent case studies for the high-pressure behavior of ionic groups since their structures combine ionic complexity and high symmetry (hexagonal P63/m
