Abstract
In recent years there has been a great increase in our knowledge of thermophysical properties of magma. The purpose of this paper is to review recent experimental developments on the properties of magma and discuss these properties at high pressures. First, the thermophysical properties of magma necessary to understand volcanological phenomena are surveyed. Secondly, the properties of magma at 1 atm are summarized with respect to two empirical laws, additivity (additive property of constituent oxides of magma) and the law of correspondihg state. Thirdly, the results of seismic wave velocities and electrical conductivity for partially molten peridotite are shown and some thermophysical properties of magma at high pressures are reviewed and discussed. In the final section, problems concerning the properties of magma that will be studied in the future are discussed.
