FEATURES OF THE DEEP STRUCTURE, GEOTECTONIC POSITION, AND EVOLUTIONARY HISTORY OF THE ZMEINOGORSK-BYSTRUSHINSKY TROUGH OF RUDNY ALTAI

This article substantiates the deep structure features and the sequence of manifestation of the geodynamic settings of Rudny Altai, which determine the distribution patterns of endogenous pyrite-polymetallic mineralization. To solve the issue at the regional level, a body of geological and geophysical data was interpreted (remote sensing maps, digital models of potential fields, geophysical sections of various types, including seismic data from the WAR geotraverse “Basalt”). When performing detailed paleoreconstructions within the Zmeinogorsk-Bystrushinsky trough, local seismic data were used. The evolutionary development model of the region is presented in the form of a set of paleosections reflecting changes in structural and material parameters at the main stages of the evolutionary development of the region in the geodynamic settings of the active continental margin and the fold-thrust belt of the collision orogen.

Keywords: paleoreconstructions, tectonic zoning, geodynamic settings.
