An Aeromagnetic Survey of the Uinta Mountains

Nelson C. Steenland

Abstract

An aeromagnetic survey of the Uinta Mountains and the adjacent basins shows a minimal anomaly over the mountains very similar to the results of a ground study by Behrendt and Thiel published in 1963. However, the interpretation of the airborne data shows that the minimum is actually not negative but simply a nonanomalous area between two intrabasement anomalies caused by changes in magnetization within the Previous HitmagneticTop basement or within the Lower Precambrian beneath the metasedimentary series of the Middle and Upper Precambrian. Consequently, the mountain mass is considered to be a nonmagnetic suite of metasediments in the form of a wedge of material more than 35,000 ft thick and about 110,000 ft wide on outcrop within the surveyed area.
