Abstract:

The lithostratigraphy of the Ramagiri Greenstone belt has been studied using IRS – P6, LISS-IV satellite data and the map has been cross checked in the field and has been further refined. This study has clearly indicated that the belt has lower Ultramafic Group followed by Greenstone Group that in turn is overlain by Sedimentary Group (located in the Karnataka state and is known as Kustigi-Hungund belt). The Ramagiri Greenstone belt is studied in association with the associated granitoid plutons and gneisses. The basement- cover relationship is not exhibited by this belt. The details about the above stated stratigraphic column are documented in detail in the thesis. Amongst the type areas, Lepakshi is in Anantapur district in Andhra Pradesh and the Ilkal and Muddenur are in Karnataka State. Since, the greenstone groups of rocks are predominant; the belts are designated as greenstone belts. The Ramagiri Greenstone belt has the Lepakshi and lower part of Ilkal Formations located in Anantapur district. Hence, the work is restricted to the two said formations only. Ilkal is located in the Karnataka State. Hence, the place called Polepalle located nearer to Ramagiri in Andhra Pradesh has been selected as a Proto-type area The Ramagiri Greenstone belt is known for gold mineralization. Ramagiri was popular since pre-independence days because of the occurrence of gold in the area. Gold was mined earlier by John Taylor & Company and in the recent years by Bharat Gold Mines Limited (BGML). Gold in this area is localized in the meta-basic volcanic.
