Structural and geological features of ore zones in the southeast of the Siberian Platform

The article presents the results of the structural zoning of the Eganja area, the analysis of the spatial distribution of fracture systems in the southeastern part of the Siberian platform in order to identify promising silver-polymetallic areas for prospecting and appraisal work. The conducted studies show that the crushing zones were formed under conditions of intense movements with repeated renewal of their contacts, expressed in crushing and metasomatic replacement. At least two stages are established: opening and filling of cracks with quartz and quartz-carbonate mineralization in a tension setting oriented perpendicular to the walls of these cracks; vertical displacements along fractures and formation of lenticular bodies of breccia structure, in which early quartz-carbonate vein-veinlets are crushed and cemented by late veinlets of several generations of carbonates. Local anomalies of polarizability, areal anomalies of increased polarizability along the Western ore-tectonic zone, as well as low-contrast anomalies of the magnetic field in the northwestern part of the Northern zone were revealed. The correlation of the ridges with the minima of the magnetic field is observed. Studies of silver ore objects made it possible to reveal both a fundamental similarity in their composition in polymetallic ores, and significant differences, primarily explained by the composition of magmatism.
