Large ring, arc and radial structures were identified based on complex processing of the multispectral satellite imagery of the Landsat apparatus. These structures control the position of gold mineralization of the Toupugol-Khanmeyshorsky ore district (Novogodnenskoe ore cluster, the Polar Urals). The comparative characteristic of this territory with the Turinsk-Auerbakh ore district (Auerbach ore cluster, the Northern Urals) was held. Similar geological features, regularity of the structures and location of gold mineralization in the system of morphostructures were revealed. For the first time, the depths of the formation of magmatic chambers were determined for the Novogodnensky and Auerbach paleovolcanic structures. These chambers were located at depths of ~4 km and ~20 km, respectively in the upper and middle parts of the earth's crust. These are sitting. The Novogodnensky structure is a monogenic structure. It formed under the influence of one leading geological process. The Auerbach structure is larger and more complex structure; it is characterized by a long and multi-stage development. The paleovolcanic reconstruction showed that the root (focal) part of the Auerbach structure plunges from the southeast to the northwest during of the magmatic process evolution. 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.

The development of technological progress provides more opportunities for indirect monitoring of changes in the environment. Remote sensing is one of The most accessible and reliable sources of information. In this work, we used satellite images from the Landsat family. The theoretical justification of the research question is given. The research methodology was developed. Collection and processing of satellite images for various time periods. A series of schematic maps based on remote sensing Data has been created. As a result of digitization of satellite images, 9 glacier contours were obtained by year. We determined the area of the Romantics glacier and found that it lost at least 60% of its original area. These studies were used to build a series of cartographic schemes that clearly show the reduction of the glacier area. It is concluded that the use of remote sensing allows you to solve problems, monitoring the object. The use of this method allows not only to save time for field work, but also material costs for expedition equipment and various equipment. This method can be tested on any objects.

The questions of the using of domestic and foreign spacecraft (SC), as well as Earth remote sensing (ERS) equipment for search and predication of gold mineralization on the example of the promising and difficult to approach areas of the Polar and the Northern Urals are discussed in the article. The solution of this problem is showed on the example of the prospective areas of the Arctic and the Northern Urals based on analysis of Landsat 7 multispectral images. Hidden structures (arc, annular, and radial) were detected with help of analyses of Landsat 7 imagery. Hidden structures determine the position of gold mineralization of the Toupugol-Hanmeyshorskogo (the Novogodnenskoe ore field, the Polar Urals) and the Turinsko-Auerbahovskogo (the Auerbachovskoe ore field, the Northern Urals) ore regions. The decision of this problem is given on the example of the promising territory of the Polar Urals with the use foreign SC the Landsat 7. Comparative analysis of the existing SC of ERS has been carried out, this target information has in the public domain. The onboard equipment installed on domestic spacecraft and the information obtained with use onboard equipment meets the existing requirements. These requirements are placed to onboard equipment to solve the problem of search and predication mineralization. At the same time, the capabilities of the deployed domestic orbital grouping of SC of ERS transcend the capabilities of SC of ERS the Landsat 7. Opportunity of obtaining geospatial information with the use of pseudospacecrafts is being considered. These have several advantages over SC and unmanned aerial vehicles.

The paper describes two records of species of the genus Pseudobaeospora Singer emend. Bas. P. pillodii (Quel.) Wasser, collected in 2009 in the Teberda State Nature Reserve, was found before in Altai [reported as P. oligophylla (Singer) Singer, the type species of the genus], as well as in the Polar Urals. P. pyrifera is new to Russia. The descriptions are illustrated by line drawings and colour photographs.
