Abstract

A relation between the thermo-electric potential of electronically conducting crystals and the temperature at which they are formed is deduced, certain conditions remaining similar. A device for measuring the thermo-electric potential of pyrite against a metal and the empirical relation of the potential to the temperature of formation is described. Used in combination with two-phase liquid inclusion measurements, the device also serves to measure the hydrostatic pressure at the time the pyrite crystallized.
