Mr. Selemani Silingi Re-allocation of resources in exploration is one of the significant trends of the last five years. ... Geophysical imaging techniques can be applied in mines for a variety of applications, including orebody delineation, hazard detection, and exploration. Geophysical data are used routinely in mineral exploration to delineate the geology of an area.Because geophysical attributes are sparsely sampled, interpolation methods are used to gridthe individual sets of data. The physical properties of rocks have been used to devise geophysical methods that are essential in the search for minerals, oil and gas and other geological and environmental problems. The following example is from an exploration program completed at high altitude (from 3800 to 4550 m ASL) in the Chilean cordillera over the Santa Cecilia porphyry target of the Cerro Grande Mining Corporation. Geophysical data are used routinely in mineral exploration to delineate the geology of an area.Because geophysical attributes are sparsely sampled, interpolation methods are used to gridthe individual sets of data.

Geophysical methods such as gravimetric, magnetometric, magnetotelluric, seismic are often combined to obtain more accurate and reliable results. Geophysical techniques also exist which can be of help in locating cavities, backfilled mineshafts, and dissolution features in carbonate rocks, and there are other techniques which can be extremely useful in determining the stiffness properties of the ground. Remote sensing is becoming an important and useful tool in mapping large, remote areas and has many applications in geosciences such as geologic and geo-structural mapping, mineral and water exploration, hydrocarbon exploration, natural hazards analysis, and geomorphology. geophysical applications. all these methods help in mineral exploration. Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties. Geophysical techniques have been applied to petroleum exploration since early in the 20th Century. ... Unit mapping is useful in oil and mineral exploration, since … area.
