Why Use Aeromagnetic Surveys?

2015-1-5 · There are many benefits of aeromagnetic surveys, including mineral and petroleum exploration, geological mapping, tectonic studies, groundwater, geothermal, archaeological and engineering projects. Most mining companies now rely on aeromagnetic surveys as the first stage of prospecting and to determine where to focus detailed studies.

Abitibi Geophysics | Airborne magnetic geophysical surveys

This type of survey is used by the government geological service and is quite useful for land-use development and planning. It is also used by mining and oil exploration companies, as well as for hydrogeological, archaeological, environmental and even military research. What are the advantages of an aeromagnetic geophysical survey?

Aeromagnetic Surveying - ScienceDirect

Most exploratory aeromagnetic surveys, howPver. must be more precise and must be conducted close t o the surfare of the ground, where turbulent air and frequent maneuvers of the aircraft introduce violent motion that materially increases the error in the oricni ing system and therefore in the magnetic measurement.
