Mid-Proterozoic Intraplate Alkaline Magmatism in the Eastern Dharwar Craton of India: The Cuddapab Province
Subscribe/Renew Journal
In the Dharwar craton, the recently recognized Cuddapah intrusive province hosts an array of mid-Proterozoic alkaline and non-alkaline intrusives; the latter are represented by two manifestly voluminous magma types: gabbro and granitoid, which are marked by a bimodal association. Here we present the tectono-magmatic framework of the Cuddapah intrusive province and in the light of it, the petrology, geochemistry and genesis of alkaline rocks are discussed to highlight the mid-Proterozoic intraplate alkaline magmatism in the eastern Dharwar craton.
