DETERMINATION OF INTEGRATION AREA (RADIUS R) IN MODELLING GRAVIMETRIC ANOMALIES Summary At present, a necessity frequently arises to determine gravitation effect for a model defined by the seismic horizon that sometimes undulates over a large area. In this connection a problem exists how the structures, remote from the point in which the effect is determined, should be taken into account to obtain the required precision in calculations of Δg. This problem can be put down to the determination of the length of radius R of the integration area. The length of radius R depends upon the kind and magnitude of undulation of seismic horizon, and upon the depth of its occurrence. This dependence is illustrated by the curves shown on Fig. 7. By means of the curves mentioned above and using successive approximations we can determine the length of radius R for each undulation of the seismic horizon.
