Plutonites

      The plutonic magmatites (plutonites) resulted from the solidification and crystallization of magma in major depth below the surface. During this process progressive crystallization of silicate melt takes place. This fractionated crystallization cased a magma differentiation and formation of a suite of plutonites. Also assimilation of materials from surrounding rocks of the magmatic chamber affects the composition of plutonites.
