Abstract
Kalpatta granite is one among the acid plutons puncturing the Precambr ian rocks of Kerala consisting of three dominant phases. The polyphase pluton is a well-differentiated, calc-alkaline, peraluminous, post-or ogenic, A-type granite ranging in composition from granite to granodio rite-adamellite. Geochemical discriminant diagrams, mineralogy, and ma jor and trace element chemistry suggest that the variants are products of polyphase late magmatic crystallization.
