TL;DR: The Ravipadu gabbro pluton (RGP) is one of the basic intrusives occurring within the deep Precambrian crust composed of amphibolites and granulites in the Prakasam igneous province of India.

TL;DR: A petrochemical comparison of the QS and NS suggests that they are derived from a feldspathic residual liquid by liquid immiscibility under variable P H 2 O and P CO 2 conditions as mentioned in this paper.

TL;DR: The gabbro plutons of Boggulakonda, Settupalle, Purimetia, Pasupugallu and Chimakurti in the Prakasam alkaline province (PAP) in Andhra Pradesh occur in a narrow zone (east of the Cuddapah basin) within the Precambrian amphibolites and granitic gneisses.

TL;DR: The doleritic and basaltic dykes of Ravipadu in the Prakasain Province traverse and extend beyond the gabbro pluton and exhibit ophitic -subophitic, intergranular and equigranular textures as mentioned in this paper.

TL;DR: The calc-alkaline complex of Chanduluru (CL) in the Prakasam alkaline province of Andhra Pradesh is composed of two distinct petrographic suites viz. a gabbro-diorite suite and a melasyenitegranite suite as discussed by the authors.
