Analysis of gravity and aeromagnetic data, San Francisco Mountains and vicinity, southwestern Utah

Abstract

regional geologic structures in the san francisco mountains vicinity southwestern utah are investigated using aeromagnetic and gravimetric data aeromagnetic data indicate a buried tertiary pluton whose north boundary runs east to west across the study area and which extend beyond the coverage of the aeromagnetic map to the east south and west the bouger gravity anomalies reflect horst and graben structures typical of the basin and range province and indicate a density contrast of plus ten grams per cc is associated with the local intrusive cupolas
