Fundamental aspects of structural phase transitions are discussed in view of XAFS measurements of the local structure below and above To. The experimental results show that the local structure and the order parameter have very different temperature dependencies. In particular, while the order parame

The enthalpy of calcite has been measured directly between 973 K and 1325 K by transposed-temperaturedrop calorimetry. The excess enthalpy has been analysed in terms of Landau theory for this tricritical phase transition. The zero-point enthalpy and entropy allow estimates of the parameters a and C
