This work is aimed at the practical application of satellite imagery data for the selection of promising areas during geological exploration work in conditions of medium-low mountainous terrain and a ...sharply continental climate. The processing results and analysis of WorldView-2 data within the Talmanskaya area are presented in order to identify zones of hydrothermal-metasomatic changes in rocks that are promising for identifying of gold-polymetallic mineralization. The choice of the study area is due to sufficient geological knowledge and the absence of man-made formations that affect the result of processing satellite imagery materials. To increase the spectral information content of the WorldView-2 data, the spectral channel ratio method was used, as a result of which a pseudocolor RGB composite was created that displays the spectral characteristics of objects on the Earth’s day surface, in particular, minerals of the oxide/hydroxide group containing transition iron ions (Fe

and Fe

). A comparison of satellite data processing results along with geological information made it possible to identify spectral anomalies as indicators of the presence of near-ore changes, which are an important search criterion for hydrothermal deposits.
To assess the capabilities of high-resolution multispectral satellite imagery in prospecting for coastal placers and deposits of hydrocarbons in the northern seas of Russia, the data from the Russian

Resurs-P
(geotone) spacecraft are used. This satellite imagery with a terrain resolution of 5 : 1 m makes it possible to carry out research on a scale of 1 : 25 000 to 1 : 5000 and opens up new opportunities for mineral exploration in the coastal zone, since it allows identifying structural units that control the location of coastal placers and hydrocarbon deposits.
An essentially new method for the allocation of diamondiferous kimberlite pipes against surrounding rocks is proposed. The method is based on the interpretation of multispectral LANDSAT-7 ETM+ ...satellite images; it allows one to find the most promising areas within perspective sites revealed by other methods. It is demonstrated that application of GIS technologies for comprehensive use of geological, geophysical, and mineralogical data and the results of the interpretation of satellite images is efficient for predicting kimberlite diamond deposits in both studied areas and poorly explored territories.
Satellite imaging is interpreted to reveal deep faults that mark the boundaries of structural blocks and hidden basement faults with feathering of the N-NE strike that govern the localization of ...diamondiferous kimberlite pipes in the central part of the Arkhangelsk diamondiferous province. Space-based imaging shows that the reference region of the Zolotitsky ore field is characterized by a dense network of faults in northeastern and northwestern strikes. The ring structure located at the junction of the Ruchevsky Ledge and the Chubal Step is of greatest interest in the northern part of the considered area. As in the reference Zolotitsky field, the high density of lineaments of different orientations, the values of the magnetic field, and the thickness of the sedimentary cover make this structure a priority for ground-based prospecting.

Sr and the data of the Landsat multispectral space survey (1977–2011) for the Kaluga and Bryansk oblasts of Russia. The radiation index inferred from the ratio of the luminance characteristics for Landsat satellite channels 1 and 4 is proposed for the assessment of the radiation situation.
The methods of a complex analysis of materials of space, gravimetric, and magnetometric surveys were developed on the basis of a study of reference fields of the Norilsk ore region (Imangda, etc.) ...for detection patterns of the localization of Cu–Ni (with PGMs) mineralization in intrusive complexes of the northwestern frame of the Siberian Platform.
The differentiated Bushveld complex is studied by remote-space and gravimagnetic methods. The syncline of Western Bushveld is recognized in the southwestern part of the complex, which is ...characterized by a radial and ring structure of the higher order. The structures, which control the localization of Pt mineralization, are revealed and the possible use of the Landsat 7 ETM+ multizonal space survey is shown for recognizing the rocks of the Basal, Critical, Main, and Upper zones of the norite complex of Western Bushveld.
The active regions (ARs) on the Sun, which are distinguished by high values of the flare index and simultaneously developed outside activity complexes (ACs), have been analyzed. Thirteen such objects ...were identified in cycle 24. We showed that these ARs belong to the category of relatively long-lived large groups of sunspots, characterized by an increased rate of area growth. These ARs are part of the AR complexes, connect with other AR systems of high coronal systems, including trans-equatorial ones. We associated some of these ARs with short-lived (less than 3 Carrington rotations) ACs and some ARs are components of complexes of ARs. All 13 considered ARs were located near coronal holes.
Abstract
This article examines the cultural landscape as a prerequisite for the socio-spatial strategy formation for the development of a small town in Bashkortostan. The authors of the article ...analyze the social, cultural contexts of small towns in the republic as the aspects of the city cultural landscape formation. Revealing the continuity of cultural, national and regional patterns of land use and management among the small towns’ residents, the authors of the article propose to consider the cultural landscape as an identity element of a small town. The article draws the conclusions about the need to use the patterns of the cultural landscape of a small town as the fundamental design frameworks for the new city spaces’ development. Following the general algorithms of urban strategizing, namely the identification of the city’s self-identity, the article proposes to use the characteristics of the cultural landscape as a semantic “core” of the small towns’ self-identification in Bashkortostan.
