METHOD FOR CALCULATING GRAVITY ANOMALIES RELATIVE TO A QUASIGEOID

A method for calculating gravity anomalies relative to a quasigeoid is described. The following formulas are given: reduction of values of the normal gravity from the ellipsoid surface to the quasigeoid surface; calculation of the conditional density of rocks of the Bouger plate; calculation of gravity anomalies relative to the quasigeoid. An example of comparison of the Bouguer gravities and anomalies relative to a quasi-geoid is given; it shows the advantages of the latter for the geological interpretation of gravity survey data.
