Tholeiitic - Opis:
- The Bethampudi anorthosite complex is essentially a leucograbbro (gabboric anorthosite and anorthositic gabbro), anorthosites, amphibolites, and pegmatite occur as concordant or discordent bodies. This work involves detailed geological geochemical investigations of amphibolites so as to reveal their possible protolith. The field relaltions, major, trace and rare earth element compositions of ampbibolites suggest that they are petrogenetically related to anorthosites by fractional crystallisation. Protoliths of the amphibolites show a tholeiitic signature that prevails over the sub-alkaline nature and E-MORB affinities. They were generated from a depleted mantle surface with the influence of a subduction and within-plate components.
