Aeromagnetic Expression of Ancient Volcanoes
Qualitative illustration of aeromagnetic polarity interpretations, using Ute Mountain as an example. A: Elevation map of Ute Mtn. B: Measured aeromagnetic field (reduced-to-pole) over Ute Mtn. C: Hypothetical aeromagnetic field assuming normally and uniformly magnetized Ute Mtn. D: Hypothetical aeromagnetic field assuming reversely and uniformly magnetized Ute Mtn. Note similarity between B and D, leading to interpretation that Ute Mtn. is at least mostly composed of reversely magnetized rocks.
