Sectioned in 4, torn in half along vertical fold, and mounted on cloth. Aeromagnetic data over a part of Maiduguri and Environs of the Southern Chad Basin, Nigeria was analyzed. The aeromagnetic anomaly map, its qualitative and quantitative interpretation helped in identifying the nature and depth of the magnetic sources in the study region.

Get this from a library. Aeromagnetic map and interpretation of magnetic and gravity data, Circle quadrangle, Alaska. [John W Cady; Florence R Weber; Geological Survey (U.S.)]. 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.

Kucks. Open-File-Report See, for example, the Bagdad aeromagnetic and geologic maps (Pis. 8, 9).Mineralized regions exist around the periphery of a granite body. This is reflected on the magnetic map by a low, featureless area over the granite proper with steep magnetic gradients over the flanks.
