Red Sanders as a Stratigraphic Guide in The Correlation of The Cuddapah Formations

Dr. S. Siddi Raju

Abstract :

From the studies carried out by the authors in Collaboration with the Geological Survey of India and State Forest Department, it is observed that the natural distribution of Red Sander plant (Pterocarpus santalinus Linn. f.) is almost wholly confined in the entire world to the tropical dry deciduous forests in the Palakonda, Veliknoda and Lankamalai hill ranges, which lie between 13°30’ and 15°0’ north latitudes and 78°45’ 79°30’ east longitudes in Chittoor, Cuddapah and Nellore Districts of Andhra Pradesh state in South India and comprise essentially of Nagari Quartzites, Cumbum Shales and Quartzites, Irlakonda Quartzites, Pullampet Quartzites and Shales and Bairenkonda quartzites of Cuddapah Supergroup of proterozoic era. From its restricted geographical and geological distribution, it is suggested that Red Sanders could be used as a stratigraphic guide to recognize a group within the Cuddapah Super group. While agreeing with the latest classification of the Cuddapah Supergroup by the Geological Survey of India that the Cuddapah Supergroup consists of the Papaghni, Chitravathi and Nallamalai Groups, a case has been made out to include all the geological formations supporting the growth of Red Sander under the Cheyair Group a term abandomed in the latest classification of the Geological Survey of India, and fix its stratigraphic position between Chitravathi and Nallamalai Groups
