Interpretation of Aeromagnetic Anomalies Between Latitudes 37 Degrees N and 38 Degrees N in the Eastern and Central United States.
Abstract
An aeromagnetic map across the eastern and central United States between latitudes 37 deg N and 38 deg N reflects the regional structure and lithology of the magnetic crystalline rocks. The major crustal units that are delineated are the Appalachian Mountain system, the buried southwesterly extension of the Grenville province, the prominent fault zones across Kentucky, southern Illinois, and Missouri, the igneous rocks of the St. Francois Mountains and vicinity, and the buried belt of lowgrade metamorphic rocks in southeastern Kansas. The map also reveals a series of conspicuous, essentially east-trending magnetic lineaments, anomaly trends, and breaks in anomaly pattern along the entire survey area.
