The ABEM WADI VLF instrument, including the antenna, battery, measuring unit, and GPS, was used . The typical VLF survey configuration is shown in Fig. 1a. The survey was conducted along a line that was almost parallel to the primary magnetic field (x-axis), and at the same time perpendicular to the direction of the geological strike as well as ...
The VLF WADI instrument displays the filtered real anomaly on the screen, and this anomaly can be roughly interpreted on site. The VLF-EM geophysical method is a quick and powerful tool for the study of shallow conducting lineament features in the near-surface earth (Telford et al., 1977). ... (VLF) range between 15-30 kHz.

The ABEM WADI VLF-EM Instrument used to measure the EM response is a portable instrument which measures the electrical properties of the subsurface, using EM induction as detailed in McNeil (1980a). In this work, thirteen EM profiles were made using a 20m coil spacing, with an expected maximum
The ABEM WADI VLF-EM receiver unit was used for the data col-lection. The transmitter used for this study is that of Great Britain (GBR) with frequency range of 15.2-15.6 KHz. The direction of the transmitter (T X) is approxi-mately parallel to the strike direction. The instrument measures the tangent of the tilt

Parts of the Eastern Basement Complex of Nigeria. The field data were collected using ABEM Wadi VLF (very low frequency) electromagnetic instrument with other accessories. A transmitter located at Cutler, Maine USA, designated as NAA with 24.0 KHz frequency and 1000Kw transmission power was used throughout the data collection exercise.

The EM16 VLF Receiver is the most widely used electromagnetic geophysical instrument of all time. Local tilt and ellipticity of VLF broadcasts are measured and resolved into inphase and quadrature components of VLF response. The EM16 has discovered several base and precious-metal ore bodies and many water-bearing fractures and faults.
