Petrochemistry and petrogenesis of Kalpatta granite, South India

摘要

Kalpatta granite is one among the acid plutons puncturing the Precambrian rocks of Kerala consisting of three dominant phases. The polyphase pluton is a well-differentiated, calc-alkaline, peraluminous, post-orogenic, A-type granite ranging in composition from granite to granodiorite-adamellite. Geochemical discriminant diagrams, mineralogy, and major and trace element chemistry suggest that the variants are products of polyphase late magmatic crystallization. [References: 25]
