The report examines methodological aspects of digitizing historical geological data in Leapfrog Geo, a software widely used for three-dimensional geological modeling of mineral deposits. The study addresses the problem of geometric inconsistencies arising during the integration of legacy data from maps, cross-sections, and other graphical sources. It is shown that improper spatial referencing and rigid alignment between plan and section data lead to defective wireframes and distortions of structural elements. The work outlines approaches to digitizing faults, contact surfaces, and stratigraphic boundaries, taking into account interpolation algorithms used in implicit modeling. The necessity of maintaining controlled gaps between digitized elements, avoiding strict adherence to sampling data, and introducing offsets from fault planes is substantiated. The influence of newly acquired drilling data on model stability is also demonstrated. The results indicate that proper digitization strategies significantly improve model consistency and flexibility, which is critical for accurate geological interpretation and efficient data management in modern digital geological environments.

The report addresses the integration and interpretation of multi-scale geological and geophysical data for exploration of territories prospective for critical mineral resources, using case studies from the Lake Kivu region and the Kandinskaya area in Russia. The key problem lies in the limited reliability and resolution of existing geological maps and the need to refine subsurface structure and mineralization patterns. A комплекс approach was applied, combining geological mapping, magnetic surveys, electrical resistivity methods, and radiometric analysis. The results demonstrate that integrated analysis of geophysical fields and geological frameworks enables the identification of concealed ore bodies that do not outcrop, as well as the delineation of promising targets. Copper-nickel mineralization zones, uranium and thorium anomalies, and refined lithological and structural boundaries were identified. The study highlights the practical importance of geophysical integration in improving exploration efficiency and supporting early-stage drilling decisions in underexplored regions.
