Geological Position and Structural Control of Ore Mineralization in the Toupugol–Khanmeishor District (the Polar Urals) Based on the Remote Sensing Results

Abstract: Large ring, arc, and radial structures have been identified by complex processing of the multispectral satellite imagery of the Landsat. These structures control the gold mineralization position in the Toupugol–Khanmeishor ore district (Novogodnenskoe ore cluster, Polar Urals). This area has been compared with the Tur’insk–Auerbakh ore district (Auerbakh ore cluster, Northern Urals). Similar geological features, regularity in the structures, and the location of gold mineralization in the system of morphostructures have been revealed. The formation depth of the magmatic chambers has been determined for the Novogodnenskoe and Auerbakh paleovolcanic structures for the first time. These chambers are located at depths of ~4 and ~20 km, respectively, in the upper and middle parts of the earth’s crust. The Novogodnenskoe structure is a monogenic structure. It was formed under the influence of one leading geological process. The Auerbakh structure is a larger and more complex structure; it is characterized by a long and multistage development. According to the paleovolcanic reconstruction results, the root (focal) part of the Auerbakh structure plunged from the southeast to the northwest during the evolution of the magmatic process. Gold mineralization within the studied areas of the Northern Urals is confined to the intersections of radial faults near the centers of large concentric morphostructures. © 2019, Pleiades Publishing, Ltd.
