Application of integrated geophysical techniques to delineate favourable structures and conductive zones for uranium mineralization in Narasinghpuri-Salwari Areas, Sikar District, Rajasthan

Geophysical techniques have played an important and indispensable role in delineating structures and conductive zones for uranium exploration in several areas in North Delhi Fold Belt (NDFB). Detailed magnetic and induced polarisation surveys conducted in Narasinghpuri-Salwari area, Sikar district, Rajasthan brought out structural features and conductive zones. Present study area is northern extension of well known Rohil Uranium Deposit (RUD), along the albitite line. Surface and subsurface geological data of the area suggests that the uranium mineralization is structurally controlled, associated with deep seated fractures/along axial regions of folds. In NDFB, uranium mineralization is closely associated with disseminated sulphides which highlights importance of induced polarisation survey in the study area
