[en] Geophysics is an integral part of most uranium exploration programmes. In India, the induced polarisation technique is being widely employed to locate buried uranium bearing horizons which are associated with sulphides. The inherent drawback with this method has been its inability to demarcate the target occurring in adverse topographic conditions. In this paper, a case is chosen from Arbail, India to explain the importance of dynamic parameters computed from the IP transient decay curves to define the ore bearing horizons precisely.
