Abstract
Several lensoid bodies of carbonatite occur within a wide zone of fenitisation in the granulite terrain of Kollegal taluk, Karnataka. These are emplaced along deep NNE-SSW fracture system and are associated with pyroxenite, talc-tremolite schist showing varying degree of fenitisation. The sovite and beforsite varieties show high percentage of SiO2 due to contamination during emplacement The Fe20 3 , MnO and MgO values of Ajjipuram carbonatites broadly compare with the Koratti carbonatites occurring on the eastern part ofthe mobile belt with similar tectonic history.
Keywords
