Abstract: The behavior of calcite at pressures up to 1000 GPa is simulated taking into account the high-pressure phase transition. The shock-wave loading of calcite was calculated using a thermodynamically equilibrium model. A few-parameter equation of state of the Mie--Gruneisen type is used to describe the behavior of condensed phases. In the phase-transition region, the components of the sample under study are considered as a mixture of low- and high-pressure phases. The shock Hugoniots of single and double compression are constructed in the pressure range from 1 to 1000 GPa, and the heat capacity along the normal isobar, entropy as a function of temperature, and the thermodynamic potential along the shock Hugoniots were calculated. The simulation results were verified against experimental data and available calculation results
