Abstract : Existing methods of computation of the vertical gradient making use of gravity anomalies, under assumption that these anomalies are being observed on a plane surface, are investigated. In reality, however, terrain is never perfectly flat. The influence of inclinations of the terrain was estimated with the help of Earth's models in the form of a truncated cone, a cone with a rounded - off apex, and a ravine of infinite extension. The case was also investigated when the anomalies created by a point mass are given on an inclined plane surface. Errors of the vertical gradient value reach several tens per cent. (Author)
