Read MorePALEOGEOGRAPHY OF THE UPPER PRECAMBRIAN OF THE NORTH-EAST OF YAKUTIA
The strata of the Upper Precambrian contains various mineral resources. In the North-East of Yakutia, Upper Proterozoic formations have a local distribution; they are poorly studied and require additional fundamental biostratigraphic and geochronological examination. The physical and geographical conditions of the geological development of the Upper Precambrian still remain unclear, insufficiently substantiated and worthy of discussion. This article examines the paleogeography of the Upper Precambrian of the North-East of Yakutia. The authors establish that the formation of a cover of passive continental margins with platform (plate) and rift-related types of tectonic structures begins from the Yurmatian in the southeastern part of the Kolyma massif, . The Vendian is marked by a wide transgression and accumulation of sediments with signs of shallow water, as well as a significant cooling of the climate.
Read MoreAN ASSESSMENT OF THE POSSIBILITY OF REDUCING THE LEVEL OF POLLUTANTS EMITTED BY VEHICLES THROUGH CHANGING TRAFFIC PATTERNS
The current article assesses the possibility of solving one of today’s most acute problems, atmospheric air pollution by exhaust gases. It is assumed that it is possible to reduce emissions by changing traffic patterns, by organizing one-way traffic along parallel streets in the central part of the city, which is the part with the most traffic flow. Potentially, the implementation of this project can contribute not only to improving the environmental situation but also increase the capacity of the two central streets of the city. The research shows a real decrease in the delay time of vehicles during traffic light regulation and, as a result, a decrease in the amount of pollutants emitted.

Read MoreSOCIO-ECONOMIC ASPECTS TERRITORIAL STRUCTURES OF ECOLOGICAL TOURISM
The creation of protected areas allows to preserve unique natural territories, but their exclusion from use leads to the fact that the rights, values, interests and self-determination of the local and indigenous population are mostly ignored. Therefore, it is necessary that a careful attitude to nature is economically beneficial for the indigenous population. Rational organization of tourism, management of recreational impact in this case can play a positive role, since tourism can provide real financial support for both nature protection and local culture, as well as socio-economic development of territories. Otherwise, as practice shows, the” ecological niche” of tourism is inevitably occupied by other, more destructive types of nature management, such as deforestation, poaching, etc.
Read MoreTRANSLOCATION OF HEAVY METALS (Pb, Zn, Cu) IN THE SEROZEM-ALFALFA SYSTEM AND THEIR EFFECT ON THE ACTIVITY OF THE CATALASE ENZYME
The activity of soil enzymes depends on the biomass of microorganisms, and their vital activity depends on the ecological state of the soil system. In this paper, the relationship between the enzymatic activity of catalase and the level of heavy metal contamination of the gray-earth soil of the Turkestan region is considered. The results of experimental studies have shown that the enzymatic activity changes with an increase in the content of heavy metals (Pb, Zn, Cu).
The introduction of vermicompost (vermicompost) into the soil led to an increase in the catalase activity of the studied soil-plant system. The observed phenomenon is explained by the stimulation of physiological activity and the formation of a larger mass of microorganisms as a result of improving the agrochemical properties of serozem. The results of experimental studies also indicate a significant effect of vermicompost on the translocation ability of heavy metal (Pb, Zn, Cu). A significant part of heavy metals, forming complex compounds with humic acids contained in the vermicompost, turn into a sedentary form. Due to this, the rate of HM migration process in both the soil system and the soil-plant system is sharply reduced. Reducing the translocation of HM from soil to plants creates the possibility of obtaining environmentally friendly agricultural products.
EXPERIENCE IN THE PENETRATION AND DEVELOPMENT OF THE PAY FORMATION OF THE LENO-VILYUISK OIL AND GAS PROVINCE
The article deals with the problems of the penetration and development of wells drilled in the Leno-Vilyuisk oil and gas province. It is assumed that the reasons for individual failures in the course of geological exploration could be the poor-quality tapping of productive horizons.
The study demonstrates the negative impact of the use of clay solutions with weighting agents, which led to the formation of deep zones of penetration of the aqueous phase into the bottom-hole zone of the formation. The results of the intensification measures carried out in individual areas are also presented. To open the upper part of the section with abnormally low reservoir pressures, it is proposed to use lightweight solutions on an anhydrous basis, or clay-chalk solutions with polymers. It is recommended to carry out perforation at reduced levels, or on special buffer solutions with minimal colmatation of the bottom-hole zone in the presence of swelling clay.
It is assumed that in the low permeable Permian pay horizons, which are under abnormally high reservoir pressure, cracks are closing with a sharp decrease in pressure as a result of testing. The authors recommend Hydraulic fracturing with the use of proppants to test the assumption.

Read MorePROBLEMS OF SMOLDERING PEAT FIRES IN FORESTS AND THE ARCTIC
Forest fires can be divided into two types: flaming or smoldering, depending on the prevailing combustion processes. Both types are present in most forest fires, and despite the fact that they are fundamentally different chemically and physically, one can pass into the other. Smoldering forest fires are becoming a global problem because they cause significant air pollution, emit very large amounts of carbon, and are difficult to detect and extinguish. The central place in this topic is occupied by smoldering peat fires, which lead to one of the largest fires on Earth. Smouldering also prevails over residual burning after the flame has gone out. Finally, smoldering is an important part of forest fires in the Arctic, which are becoming more frequent. A significant part of forest fires in the Arctic occurs in the form of flameless combustion or smoldering of organic soils and permafrost on peatlands. This article provides an overview of smoldering forest fires, related environmental problems, including climate change, as well as problems in the field of prevention and mitigation of consequences.
