A Review on the Nomenclature of Angadimogar and Kumbdaje Plutons, Kasaragod District, Kerala

Pink and grey granites occur as minor, more or less circular bodies at Angadimogar and Kumbdaje areas of Kasaragod district, covering about 10 km². These granites are emplaced within the charnockites and gneisses during the Late Precambrian. These granites arc coarse grained and traversed by anastomising patches of aplite. They are in sharp contact will the country rock. The Angadimogar pluton was carlier considered a syenitic body. Normative mineralogy and petroghaphy of the Angadimogar and Kulnbdaje plutons show high content of silica and other salic minerals and confirm that they are in fact granites. The major oxide chemistry of the plutons is similar to the major granitic plutons of South India. Thus, contrary to the earlier views, we suggest that these bodies are granites.
