| Summary: | T HE mapping of the earth’s gravity field is important for several branches of scientific endeavour. In g d e s y, gravity measurements furnish a basis for determining.the overall shape of the geoid and its undulations. In studying the earth’s crust gravity measurements provide a quick and reliable method of determining variations in crustal structure. In the study of the crystalline basement rock complex gravity values used in conjunction with seismic and well data have immeasurably broadened our knowledge of both the lithology and configuration of this buried surface. Finally, such measurement have proved of great value in the search for mineral resources. The ultimate use made of gravity measurements de-pends on the method of analysis employed. The basic data for all uses are the same- the gravity observations themselves. The present report outlines the extent of a gravity observation program in Alaska, carried out by the authors. Although the areal gravity mapping in this area will take many years to complete, sufficient work has been done to furnish a nucleus for integrating past and future studies into a |
