Airborne Geophysics

  • Airborne Magnetometry

Magnetometric surveys are of particularly great value for mining and hydrocarbon exploration stages, as well as for environmental studies. By mounting magnetometers on small airplanes or helicopters, it is possible to cover large areas and obtain valuable results in a fast, versatile and economic manner.

This prospection methodology is based on the various magnetometric responses produced by bodies of different magnetic susceptibility. Under the effect of the magnetic field, the bodies located inside the Earth crust generate induced magnetization processes which are added to the terrestrial magnetic field. Magnetometry reveals therefore the contrasts of magnetic susceptibility in outcropping or in-depth bodies.

It is possible to acquire information on the depth and distribution of the basin basement, the geological and structural mapping of a certain area, and the prospectivity of mineral deposits, among others. This data is then processed and interpreted in a lab in order to generate products that can be used during the exploration.

  • Airborne Radiometry

Airborne radiometry methods are based on the natural radioactivity of uranium, thorium and potassium. It is a superficial and non-invasive exploration methodology that makes it possible to cover vast areas at a low cost and get results almost instantly. HytecAltoAmericas’ radiometers can measure concentrations of K, U and Th.
