Application of remote sensing for detection of tectonic structures and localisation of ore deposits within Biryusinsky and Krepsky-Tumanshetsky ore clusters (Eastern Sayan)

Abstract

As a result of decoding of the materials of the Russian space survey “Resource-P” (ShMSA) on Biryusinskaya area, the features of the tectonic structure of the horst-anticlinal uplifts and the graben-synclines separating them were determined, the large role of sublatitudinal disjunctions was shown in the structural diagram of the area under study, ore prospective sites were isolated. The study of the Krepsko-Tumanshetskaya area was carried out using space multispectral and panchromatic high-resolution surveys “Resource-P” (Geoton), which made it possible to determine the structural position of the ore deposits. On the Krepsko-Tumanshetskaya area, the ore-controlling structures are small along the length of sublatitudinal strike faults and the nodes of their intersection with the northwestern and northeastern disjunctions.
