Abstract

Hydrous minerals, melts and glasses may be studied by a variety of calorimetric techniques. These include measurements of heat capacities and enthalpies by adiabatic, drop, transposed-T-drop and differential scanning calorimetry, and the measurement of enthalpies of reaction by solution, drop-solution, and decrepitation calorimetry. Some calorimetric experiments on hydrous melts at high P and T are possible. The system NaAlSi3O8-H2O has been studied. It shows small negative heats of mixing which may be consistent with Stolper's model (83M/4449) of an H2O dissociation equilibrium. (Author's abstract) -J.M.H.
