Geophysical prospecting involves the use of a series of techniques and geophysical methods capable to emphasize the composition and structure of the basement. Thus geophysical methods have been developed to meet the requirements of depth and resolution required by engineering, geological and hydrogeological survey works .
Geophysical methods used:
2. Geoelectrical investigation
3. Electromagnetic investigation
- Frequency Domain (FD) and Time Domain (TD)
- Metal Detection (MD)
- Very Low Frequency (VLF)
- Ground Penetrating Radar (GPR)
Depending on the purpose in geophysical investigations are applied to one or more geophysical methods of investigation using proper equipment.
