Abstract
The study of the structure of the Precambrian crystalline complexes raised and exposed along the margins of the North Asian craton allows us to characterize the geological features of various stages of the evolution of the lithosphere. Based on these data identification of the promising metallogenic zones and local potentially ore-bearing objects can also be achieved. The goal of the performed research was to create objective models of the areas characterized by the presence of mineral deposits to identify characteristics and promising structures. Using modern geoinformation systems, the maps of the high gradient zones of the local components of geophysical fields have been created. These maps reflect the boundaries of geological complexes with contrasting physical properties. For clarity, the geophysical background was removed from the maps, and only the zones of high gradients of various geophysical fields were left. A combination of maps was performed and it was found that high-gradient zones of the various geophysical fields complement each other along the strike. Based on the obtained geophysical schemes, geological maps and field observations of geological structures, already known and new folds and faults have been deciphered. As a result, models of folds and faults that control the location of mineral resources were created. Models allow finding the common features and evaluating the minerals prospects of areas. In the framing of the Upper-Timpton dome of the Central-Aldan superterrane and in the Shamanikhin fault zone of the Prikolyma terrane, there are many high-gradient zones of the various geophysical fields observed. New ore objects can be expected to be discovered in these areas.
