Depth of principal mass anomalies contributing to the earth's geoidal undulations and gravity anomalies*

摘要

To help decipher the distribution of the principal mass anomalies within the earth, an analysis is made of the earth's potential field by simultaneously considering both gravity and geoid anomalies. Ancillary knowledge about the earth from astronomical, angular momentum, seismological, and plate tectonic studies aids in deciding between deep or broad shallow‐mass anomalies as the causative source of certain potential field anomalies.
