Abstract
The possibility of regional forecasting of new ore regions using freely available gravimetric and magnetic data is discussed. Summary matrices of gravitational and magnetic anomalies with a cell size of 2 * 2 km are used. Is Shown that with this grid, using of analytical methods is not effective, and probabilistic and statistical analysis technologies will be more effectively. The possibilities of effective solution of the problem based on the analysis of anomalous fields and their transformations using statistical methods, including lineament and cluster analysis, as well as formal prediction of mineralization using image recognition algorithms with training on reference objects are shown. As standards, both deposits and ore occurrences within the work contour and external significant objects are used.
