Abstract
Section titled “Abstract”Lamproites are mantle-derived ultramafic rocks and primary source rocks for hosting diamond apart from kimberlites.The present study area, Ramadugu lies in the North-Eastern part of Dharwar craton, along the NE margin of Cuddapah basin.These Lamproites are tube or pipe like structures and emplaced with a NW-SE trend.LISS-IV imageries were utilized to demarcate the drainage pattern, lineaments and hydro-geomorphology of the area.Ground Magnetic surveys were conducted using a Proton Precession Magnetometer (PPM) to delineate the Ramadugu Lamproite body.The magnetic anomaly maps were based on about 800 observation points along nine profiles of 500 m in length.The observation interval was 5m.The results of the present study have helped in a better understanding of the lineaments and the geological litho-units associated with the occurrence and emplacement of the Lamproite body in Ramadugu, Cuddapaha Basin, Andhra Pradesh and surrounding regions, where there is an occurrence of several Lamproites.
