Observed and Calculated Values of the Magnetic Intensity over a Major Geologic Structure

Abstract

The authors compare the observed and calculated values of the vertical and horizontal components of the magnetic field along a profile across the Los Angles Basin. A structural geologic cross section compiled from seismic, gravity and geologic data was used as a basis for calculating the magnetic field. In the San Pedro Hills portion of the cross section the calculated and observed values disagree, indicating that the granitic basement rocks lie at greater depths then shown in the structure section.
