Abstract—Magnetic method is the simplest method to identify the geological features which are preva由ng in the subsurface. The study area is located in western part of the Cuddapah Basin which mainly comprised Tadipatri shales and sills. Tilt derivative technique is used to delineate the faults and hidden sills in the subsurface and constructed a structural map. There are twenty faults are identified in this area which are trending mainly in two directions NW-SE and NE-SW. The hidden sill segments are the source for high magnetic anomalies in the middle part of the study area and these segments also trending in same direction as sill outcrops in the northern part.
