Magnetics and Gravity

| Gravity and magnetic surveys are used in regional and deep exploration, in the prospection of deposits and in engineering and environmental geophysics. Usually, these methods are performed to cover prospective areas before the application of other cost intensive exploration methods. Integrated interpretation of seismic data with high-resolution gravity and magnetic surveys is one efficient tool to solve problems in areas with complex geology. For data acquisition highly sensitive gravimeters (Scintre Autograv CG-3M+/CG-5M, LaCoste & Romberg, Sodin and Sharpe) and magnetometers (proton precession magnetometers, optically pumped vapor magnetometers, fluxgate-gradiometers) as well as state of the art geodetic instruments (electro optical tachymeter, satellite navigation system for real-time GPS) are provided. Magnetic surveys can be performed on-shore, airborne, off-shore or in boreholes. For data processing, modelling and geological interpretation a variety of software modules are in use. Practically all reductions, corrections, field transformations and different inversion techniques as well as 2D, 2.5D and 3D modelling are feasible. |
