Gravity is a high-precision method for measuring density contrasts that may relate to economic resources buried at depth. It is applicable for mineral exploration, geothermal exploration, and oil and gas exploration.
Gravity survey is used as supplementary to raw materials exploration and as reconnaissance one to design seismic works. Application of gravity method is especially recommended in the case of rock complexes screening seismic energy, as the screening or attenuating layers are transparent for gravity field. Qualitative and quantitative interpretation of gravity data provides information on location, density and depth of geological structures. Maps of gravity anomalies indicate location and dimensions of the structures and extent of tectonic zones.
PPZG is fully experienced in performing designing, processing, interpretation, inversion and consulting services on Gravity projects.
The shape of a particular gravity anomaly is usually indicative of the dip and depth extent of a geologic unit if there is a significant density contrast with the surrounding rock units.
