Abstract
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 an d granitoid, which are marked by a bimodal association. Here we present the tectono-magmatic framework of the Cuddapah intrusive province and in the l ight of it, the petrology, geochemistry and genesis of alkaline rocks are d iscussed to highlight the mid-Proterozoic intraplate alkaline magmatism in the eastern Dharwar craton.
