Principal features of high-resolution aeromagnetic data collected near Albquerque, New Mexico
— V. J. S. Grauch

High-resolution aeromagnetic surveys flown in the middle Rio Grande basin north and south of Albuquerque show expressions of exposed and buried bedrock blocks on the edges of the Rio Grande rift, intrabasinal faults, shallowly buried igneous rocks, topographic effects, and several different types of cultural features. The aeromagnetic maps are especially useful for mapping intrabasinal faults in areas covered by thin, but widespread surficial cover. Expressions of faults on the aeromagnetic map are prominent and numerous, showing curvilinear patterns with many splays. The magnetic expressions can be generally explained by offsets between units having different magnetic properties. The aeromagnetic map also shows expressions of probable buried volcanoes or intrusive centers southwest of the Albuquerque Volcanoes and extensive buried basalt and intrusive centers in the southern part of the study area beneath the Rio Grande flood plain.
