Got questions?

We have answers to the most popular questions from our customers. If you can't find an answer to your question, please contact us.

What are the three geophysical methods?

Common methods of acquiring geophysical data include borehole logging, surface-based, and cross-borehole methods. Borehole logging often provides the highest resolution information on materials immediately adjoining the borehole.

How to do a geophysical survey?

In these surveys, electrodes are placed on or in the ground and a small electrical current is passed between them. The resulting voltage measurements are used to calculate the electrical resistivity of the subsurface materials. Different materials, such as rocks, soils, and groundwater, have varying resistivity values.

What is an example of a geophysical search tool?

Technologies used for geophysical surveys include: Seismic methods, such as reflection seismology, seismic refraction, and seismic tomography. This type of survey is carried out to discover the detailed structure of the rock formations beneath the surface of the Earth.

How to conduct a geological survey?

Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing methods, such as aerial photography and satellite imagery.

What is a geophysical survey?

Geophysical surveys refer to methods used to detect changes in physical properties such as gravity, magnetic fields, electromagnetic responses, resistivity, and seismic wave velocity that are associated with variations in geological conditions, often for the purpose of mineral exploration.

What is the purpose of a geophysical survey?

Generally, these geophysical surveys are employed to provide information on the distribution of geological boundaries both laterally and at depth and the structures associated with them which may have bearing on mineralization.

What are the two main methods of geophysical survey?

Magnetic techniques, including aeromagnetic surveys and magnetometers. Electrical techniques, including electrical resistivity tomography, induced polarization, spontaneous potential and marine control source electromagnetic (mCSEM) or EM seabed logging.

How to conduct a geophysical survey?

Geophysical surveys begin by first dividing the site or area of interest into survey grids. The data is then collected at various points and recorded. The instrument used in collecting data depends on the geophysical investigation methods employed.
