Abstract

Currie proposed a criterion for predicting liquid immiscibility in silicate melts with reference to their free energies before and after crystal fractionization of a melt. The present authors have calculated the rock analysis data given by Philpotts and proved the validity of Currie ’s method.

The authors are particularly interested in the study of immiscibility in the magma in relation with iron deposits. Therefore, they have also calculated the data for artificial silicate melts as well as the data from the famous Kirunavaara iron deposit.
