Abstract

High-pressure experimental data are used to evaluate the validity of the Lindemann melting criterion for minerals. The parameters required in this Lindemann expression can be determined from an inversion of thermodynamic data so that a direct comparison with experimental melting data can be made without resort to model potentials. It is demonstrated that the Lindemann expression is inconsistent with experimental melting data for a variety of substances, particularly at low pressures. In some cases (argon, sodium chloride and potassium chloride), the melting slopes observed at high pressures are consistent with a Lindemann expression. In general, it is found that a Lindemann criterion is not an adequate description of the melting behavior of minerals. Therefore, an application of the Lindemann law to obtain the melting temperatures of minerals at high pressures, and to determine the fusion curve of the earth's deep interior is, at present, speculative.
