The Ugii Nuur Lake is not only one of the small hydrologically closed lakes located in Orkhon River Basin Central Mongolia but also most vulnerable area for global climate change. Therefore, this study aims to investigate impacts recent change on water surface area. data we analyzed were various measured hydro-meteorological variables lake basin and area, which was estimated from Landsat series satellite 1986 2018. methods used Mann-Kendall (MK), Innovative trend analysis method (ITAM),...
To understand how the climate system works in continental interior, sediment cores that are approximately 30-cm long were taken from Olgoy, Boontsagaan, and Orog lakes, Mongolia. These analyzed compared with meteorological data (air temperature, precipitation, wind) stations study area. Comparison of metrological four shows similar fluctuations. When temperature was high, less precipitation occurred general. The sedimentary features measured this water content, organic matter, carbonate,...
Amorphous magnesium carbonate (AMC: MgCO3·nH2O) is a metastable phase with respect to crystalline carbonate. AMC has been suggested be an important mineral, major process of CO2 fixation in alkaline saline lakes. Understanding the role for carbon lakes requires knowledge solubility under full range relevant environmental conditions, but its poorly known low water temperatures. In this study, at 7 °C was measured laboratory experiments and compared chemical analyses samples from Olgoy Lake,...
The aim of this study was to determine the way recent climate change impacts morphometric changes in lakes various ecological zones Mongolia. We studied 4 located between 48 and 50°N as representative other environmental Mongolia determined correlation variables area, depth, volume these lakes. To analyze parameter variation lakes, we used normalized difference water index, trend analysis, aridity statistical analysis. According our calculations, have decreased during last 30 yr. Trend...
On the basis of proximate, ultimate, petrographic and IR analysis results have been confirmed that Tavan tolgoi coal is a high-rank G mark stone coal. The X-ray fluorescence ash show subbituminous has an acidic character. pyrolysis at different heating temperatures maximum yield - 5.0% liquid product can be obtained 700°C. thermal dissolution in tetralin with constant mass ratio between (1:1.8) 450°C 50.0% after decomposition COM (coal organic matter).

Abstract Several icy bodies (e.g., Europa and Ceres) likely possess near‐surface brine reservoirs, which are considered to be sources of salts on their surfaces. Previous studies have proposed processes whereby an overlying ice layer captures salinity from a freezing, subsurface reservoir. However, few field investigations been conducted investigate chemical partitioning aqueous chemistry in freezing reservoirs terrestrial analogs. Here we report results winter surveys ice‐covered,...
There has not been much study done to explain how recent climate change affects the water surface area changes in lakes different natural areas of Mongolia. Four between 48° - 50° Mongolia were chosen for this investigation because they have same climatic and solar radiation patterns. The case studies Khoton Lake high mountain region, Terkhin Tsagaan forest-steppe Khukh steppe Namir (Khar Us) Govi region emphasized relationship variables, which are temperature precipitation. In study,...
Although recent studies have detected elevated concentrations of arsenic and uranium in inland, alkaline, saline lakes, the chemical reactions associated with these enrichments are poorly understood. In this study, we used a five-year study water chemistry, characterization sequentially extracted sediments, X-ray absorption fine structure analyses (XANES) to examine geochemical behavior during evaporation Orog Lake, saline-alkaline lake arid region Mongolia. Water chemistry showed that...
