To analyze processes that may lead to long-term changes in pH, lake sediments from five small lakes in the Western and Central Caucasus were studied according to diatomaceous complexes from sediment cores. A proprietary principle of hydrological parameter unification was used to reconstruct numerical pH values. In isotopic dating experiments, a series of numerical pH values for 2000–130 years were generated for the lakes. These data indicate an absence of noticeable changes in pH in the lakes of the Western Caucasus and alkalization processes in the lakes of the Central Caucasus.

AbstractGlaciers occupy an area of ~1600km2 in the Caucasus Mountains. There is widespread evidence of retreat since the Little Ice Age, but an up-to-date regional assessment of glacier change is lacking. In this paper, satellite imagery (Landsat Thematic Mapper and Enhanced Thematic Mapper Plus) is used to obtain the terminus position of 113 glaciers in the central Caucasus in 1985 and 2000, using a manual delineation process based on a false-colour composite (bands 5, 4, 3). Measurements reveal that 94% of the glaciers have retreated, 4% exhibited no overall change and 2% advanced. The mean retreat rate equates to ~8ma–1, and maximum retreat rates approach ~38 m a–1. The largest (>10 km2) glaciers retreated twice as much (~12ma–1) as the smallest (<1 km2) glaciers (~6ma–1), and glaciers at lower elevations generally retreated greater distances. Supraglacial debris cover has increased in association with glacier retreat, and the surface area of bare ice has reduced by ~10% between 1985 and 2000. Results are compared to declassified Corona imagery from the 1960s and 1970s and detailed field measurements and mass-balance data for Djankuat glacier, central Caucasus. It is concluded that the decrease in glacier area appears to be primarily driven by increasing temperatures since the 1970s and especially since the mid-1990s. Continued retreat could lead to considerable changes in glacier runoff, with implications for regional water resources.

В статье рассматривается возможность выделения наследственных признаков геодинамической обстановки и элементов структурно-вещественных комплексов, участвующих в геологическом развитии  Кавказа, на глубинных геоэлектрических и сейсмологических разрезах для создания геолого-геофизической моделей земной коры вдоль региональных профилей. Современные структурно-тектонические и структурно-вещественные комплексы восточной части Центрального Кавказа интерполируются с основными структурами консолидированной коры и низов коры. Обосновывается научный и практический интерес корреляционной увязки глубинных коровых и мантийных структур с месторождениями твердых полезных ископаемых и углеводородов, роль границы Мохоровичича в локализации месторождений. Субширотная структура реликтового рубца (геосутуры), уверенно выделяемая по минимумам напряженности полного вектора магнитного поля по структурно-вещественным элементам (олистостромы, офиолиты, микститы) представляется убедительным наследственным признаком субдукции. Реликтовый рубец представляется выполненным тектонизированным терригенным материалом, содержащим разного размера глыбы и блоки вулканогенно-осадочных пород и ремобилизованные олистостромы пород офиолитового комплекса, что является формационным признаком геодинамической обстановки, фиксируемой в развитии структуры Кавказа. The article deals with the possibility of identifying hereditary features of the geodynamic situation and elements of structural and material complexes involved in the geological development of the Caucasus, in deep geoelectric and seismological sections to create geological and geophysical models of the earth's crust along the regional profiles. Modern structural-tectonic and structural-material complexes of the Eastern part of the Central Caucasus are interpolated with the main structures of the consolidated crust and the lower crust. The scientific and practical interest of correlation linking of deep crustal and mantle structures with deposits of solid minerals and hydrocarbons, the role of the boundary of Mokhorovichych in the localization of deposits is substantiated. Latitudinal structure of the relic scar (geostructure), confidently allocated to the minimum of the tension of magnetic field full vector on structural-material elements (olistostromes, ophiolites, mixtite) persuasive inherited character of subduction. Relict scar is represented by tectonized terrigenous material containing different size blocks and blocks of volcanogenic-sedimentary rocks and remobilized olistostromes of rocks of the ophiolite complex, which is a formative sign of geodynamic situation, recorded in the development of the structure of the Caucasus.

Based on the results of field works by A.A. Golovlev in July 2017, data on new and noteworthy species for the lichen flora of the Prielbrusiy National Park are presented. The specimens were collected in the Adyl-Su River gorge, Elbrus district, Republic of Kabardino-Balkaria. In total 75 species from 44 genera are listed here with their localities and substrates, and novelties data. Eighteen species are new for the Prielbrusiy National Park, of which twelve were found for the first time in the Kabardino-Balkarian Republic (Aspicilia cf. laevata, Blastenia hungarica, Bryoria vrangiana, Cladonia cyathomorpha, Henrica melaspora, Lasallia rossica, Lecidea promiscens, Normandina pulchella, Parmelina tiliacea, Ramalina pollinaria, Rinodina trevisanii, Rusavskia sorediata). Henrica melaspora is reported for the first time for Caucasus, Cladonia cyathomorpha is new to the Russian Caucasus. Two species (Lecidea promiscens and Rinodina trevisanii) are reported for the first time for the Central Caucasus. The genus Henrica is reported as new to the Caucasus, and the genus Normandina is new for the lichen flora of Kabardino-Balkaria.

The use of modern methods of microstratigraphic and planigraphic analyses allows the authors to speak about features of organizing life space in the Middle Paleolithic sites. The layer 6B at Saradj-Chuko grotto can be defined as an actively occupied Middle Paleolithic habitation site, where ancient humans were engaged in manufacture and use of obsidian tools. A tracelogical analysis allowed the authors to reconstruct various economic activities of ancient humans. For the first time for the Middle Paleolithic site in the northern slope of the central Caucasus, a tracelogical analysis was carried out taking into account the space distribution of tools over the site area, which allowed us to study features of human activity at different areas of the site. The new data are considered within a broad context of the Middle Paleolithic of the Caucasus, as well as the available data on economic activity and residential structures in various sites are analyzed.

The A-melt model was applied to assess the contribution snow and ice melting to river flow during the summer period of 2017 for the Bashkara and Djankuat glaciers located in the Caucasus. During the study period, the Djankuat river runoff amounted to 120 thousand m3, while the peak value of snow and ice melting was 300-400 thousand m3 per day, and on average 189 thousand m3. The significant influence of groundwater on the river flow is traced. The melt water contribution to the glacial lake Bashkara outburst manifested in the gradual accumulation of water large volumes over the summer period. The melting of snow and ice the day before the lake outburst reached 31 thousand m3, with an average value of 192 thousand m3 for the Bashkara basin. The total melting volume of the Djankuat basin was 0.016 km3, and of the Bashkara basin – 0.017 km3. As a result, the A-Melt model demonstrates the evaluation ability of glaciers’ impact on mountain rivers runoff.
