Summary

This publication provides digital flight line data for a high-resolution magnetic and radiometric survey over an area of northwest Arkansas. The airborne geophysical survey was jointly funded by the USGS National Cooperative Geologic Mapping Program and the Earth Mapping Resource Initiative and was designed to meet the complimentary needs related to geologic mapping and mineral resource research. The survey covers an irregular area 225 by 110 kilometer over the transition between the Ouachita and Ozarks Plateau physiographic provinces and includes 67,614 line-kilometers of magnetic and radiometric data. Data were collected from a fixed-wing aircraft flown at mean terrain clearance of 167 meters (m) above topography along N-S flight [...]

Purpose

The magnetic survey was flown as a component of U.S. Geological Survey (USGS) projects to improve the geologic framework for research related to mineral resource, energy resource, and geologic hazards studies in the area. Results from the survey will aid in providing insight into the magnetic signatures of exposed and concealed geology.
