Abstract
The potential capabilities of gravity and magnetic methods in the evaluation of geologic structures have been effectively utilised. Using these methods, semi-detailed surveys were conducted around the radioactive occurrences at Lotapahar (22°36'30"N. and 85°35'E.), in the western sector of the Singhbhum shear zone, primarily to decipher structural features, the common host for Uranium mineralisation.
The interpretation of gravity and magnetic data enabled delineation of a ENE-WSW trending fracture zone. Forward modelling of a gravity profile yields the sub-surface disposition of this fracture zone and facilitated planning of boreholes for uranium exploration in the area. The magnetic and the regional gravity maps indicated the contact of Chakradharpur granite and metasediments of the Iron Ore Group which is indistinct on the surface.
