Panyam study area situated in Kurnool sub-basin, India. This study area covered with different geological formations from place to place. Radiometric studies which is a very good tool for geological mapping, were carried out to identify the anomalies corresponding to these formations. From the interpretation of Radiometric contour map the anomalies can be noticed easily which are maximum correlate with these formations. For convenience two geological boundaries BL1 and BL2 also drawn in this map. Below boundary line-BL1, the larger area mostly covered with Nandyal shales, exhibit high values > 7 μR/hr except at the soil cover areas. The low anomalies < 3 μR/hr are observed above BL2 line, due to Panyam quartzites. The zone between BL1 and BL2 covered with Koilakuntla Limestone with Nandyal shales exhibit different anomalies low to high.
