This paper relates the petrological studies of pyroxenites-carbonatites from Samalpatti Complex Southern Granulite Terrane (SGT) of peninsular India. The Samalpatti complex (SC) is one of the complexes in Tamil Nadu consisting mostly associated with alkaline rocks of Carbonatites, Pyroxenites, Peridotite and Syenites. In the research area Gerigepally Pyroxenites-Carbonatites are occur as outcrops, thin lensiod bodies and bands. The study area comes under the Samalpatti Complex and situated under Southern Granulite Terrain (SGT). From the field of study area samples were collected along the fresh outcrops and well cuttings. Megascopy of the samples shows dark coloured, fine to coarse grained and massive form of pyroxenites. Pyroxene is the essential mineral, biotite and hornblende are accessory minerals and showing coarse grained poikilitic texture. Whereas carbonatites are calcite rich coarse grained rocks. In the laboratory prepared thin sections most of the Pyroxenites observed that more ultramafic minerals like augite, diopside, biotite, enstite.
