Modelling of aeromagnetic anomaly and its implication on age of emplacement of ultramafic–mafic– alkaline complex at Jasra, Assam

The aeromagnetic anomaly around Jasra in Assam, based on which the Atomic Minerals Division had discovered an ultramafic–mafic–alkaline carbonatite complex has been modelled. Inferred direction of magnetization of the source body suggested the age of emplacement of the source to be around Jurassic p...

description The aeromagnetic anomaly around Jasra in Assam, based on which the Atomic Minerals Division had discovered an ultramafic–mafic–alkaline carbonatite complex has been modelled. Inferred direction of magnetization of the source body suggested the age of emplacement of the source to be around Jurassic period which is correlated with the time of breaking up of the Gondawanaland and the northward drift of the Indian plate and crustal upheavals.
