POSSIBILITIES OF ISOTROPIC AND ANISOTROPIC TRANSFORMATIONS AND FILTRATIONS OF GRAVITATIONAL ANOMALIES
Authors/Creators
Description
This article is devoted to the issue of isotropic and anisotropic transformations and filtration of gravity anomalies. An important stage in the processing and interpretation of gravimetric anomalies is the processing stage, which involves the transformation and filtration of gravity fields to isolate local and regional anomalies from the overall anomalous field. Local gravity anomalies reflect structural heterogeneities in the density properties of rocks, while regional anomalies are associated with the deep structure of the Earth's crust and lithosphere. To perform isotropic and anisotropic transformations of gravimetric anomalies, the department has developed algorithms and the Force-Fortran programs IZOTR and ATPAZ, which enable computer-based transformations of analog and digital data using various conversion methods. The article describes the algorithm of the IZOTR program, the theory of the anisotropic palette of the ATRAZ program, as well as some results of the transformation of actual and model gravitational fields in a modern interface, as well as some results of isotropic and anisotropic filtering using the SURFER graphical program.
