The study area forms a part of Madurai block and lies in the Dindigul and Karur district of Tamilnadu, India. Madurai block is the largest Granulite block of South India. It is bounded by Palghat Cauvery shear zone in the north and Achankoil shear zone in the south. The study area falls in the survey of India Topographic sheet number 58 J/2 and 58J/6. The Kadavur structural basin is a large-scale structural formation of rock strata formed by tectonic warping of previously flat lying strata. This basins was the result of sediment that filled up a depression or accumulated in the study area and were resulted by tectonic events long after the sedimentary layers were deposited. The structural study of the area reveals three major folding and development. Geomorphology of the study area reveals a dome-basin morphometry with radial drainage patterns. The various geomorphic features such as the structural hills, bajadas, pediments, escarpments and second order relief features such as plains, plateaus, mountains ranges, large dome and basins etc are significance. Geomorphic features like structural hills, linear ridges, escarpments, colluvial fills, bajadas, pediments and buried pediments were identified and their boundaries were demarcated. Bajadas comprises of pebbles, boulders, stones and sand materials made up of quartzites, gabbros and anorthosite. Weathered anorthosite formed maximum part of the pediments. Escarpments and ridges are made up of quartzites and forms the structural hills of the study area. The entire area of the district is a pediplain. The Rangamalai hills and Kadavur hills occurring Eastern Ghats and rise to heights of over 1031 m above MSL. In the present study mainly focussed on the geomorphological features in Kadavur taluk, Karur district, Tamilnadu, India.
