PALINGENESIS:-The formation of magmas, usually of granitic composition, through selective or complete fusion of igneous or metamorphic rocks deep in the earth. Fusion occurs when the rocks are acted upon by juvenile fluids. The magmatic melts resulting from palingenesis develop further through replacement of the rock by magma that selectively assimilates components (SiO2, K2O, Na2O, AI2O3, and others) and through the formation of injection gneisses and migmatites. Granitoid magmatism in the deep zones of geosynclines results. Palingenesis may occur in part during regressive metamorphism.
