A cluster-fractal model of silicate melt structure is proposed. Plutonic and volcanic melts have great mobility due to their high temperature and low viscosity. The melt exists in a wide range of temperatures. In the liquidus-subliquidus range, it is macrohomogeneous and formed by volumes of clusters of close chemical composition and structure. Within these volumes, minerals nucleation and growth occur. The melt and crystals are characterized by a metastable state. They are stable only under fixed RT conditions.
