AEROCARE’S AERO MAGNETIC SURVEY
We specialise and have massive experience in Aeromagnetic survey / aero-geomagnetic survey .
An aeromagnetic survey is a common type of geophysical survey carried out using a magnetometer aboard or towed behind an aircraft. The principle is similar to a magnetic survey carried out with a hand-held magnetometer, but allows much larger areas of the Earth’s surface to be covered quickly for regional reconnaissance. The aircraft typically flies in a grid-like pattern with height and line spacing determining the resolution of the data (and cost of the survey per unit area).
Aerocare provides first class aeromagnetic surveys using state of the art Helicopters to attached with the latest airborne geophysical surveying gauges to locate mineral deposits as well us oil deposits
Aeromagnetic surveys are widely used to aid in the production of geological maps and are also commonly used during mineral exploration and petroleum exploration. Some mineral deposits are associated with an increase or decrease in the abundance of magnetic minerals, and occasionally the sought after commodity may itself be magnetic (e.g. iron ore deposits), but often the elucidation of the subsurface structure of the upper hydra crust is the most valuable contribution of the aeromagnetic data. It has also been used to find buried fault zones that are prone to damaging earthquakes
Detection of geological features such as faults, horsts and grabens is important in geothermal exploration. Under favorable circumstances, these features can be successfully picked up by high-precision aeromagnetic surveys.
Aeromagnetic surveys are quite expensive, and interpretation of data is often complex. Magnetic data reflect the variations in the Earth’s magnetic field that arise from the distribution of magnetic materials in the ground.
