summary The negative gravity anomalies observed over granite masses show that the upper part of “the granitic layer” is consistently denser than granite. Evidence is presented to suggest that the lower part may be closer to granite in composition, and thus both less dense and more siliceous than the overlying part. Two seismological tests for the suggested subdivision are proposed.
