The amplitude of analytic signal of real component of very low frequency electromagnetic (VLF-EM) and resistivity method were used to determine the location of fracture zone in part of hard rock area of Mirzapur district, Uttar Pradesh, India. The satellites Imagery was used to delineate the lineament besides prior information for appropriate locations using integrated geophysical surveys. The VLF-EM data was acquired along the six VLF traverses profiles. The results were obtained using Fraser and Karous-Hjelt filters to correlate with the Hilbert transform and amplitude of analytic signal of real component of VLF-EM data and the amplitude of the 2-D analytic signal of the real component in the form of an image of the profile. The real component of the Hilbert transform generates an approximate depth of fracture zone in part of hard rock area. It was correlated with results based on resistivity sounding and geoelectrical cross section.
