This study presents new data on the chemical composition, content, and distribution patterns of stable oxygen hydrogen isotopes in natural waters from Issyk-Kul intermountain artesian basin. area has significant balneological potential due to abundance mineral with diverse temperatures, gas compositions, total dissolved solids (TDS). The uniqueness this region lies coexistence two distinct types waters: fissure-pore confined basins fissure-vein associated tectonic fault zones rock...
In the present article, radon and uranium concentrations of nineteen occurrences mineral waters Pamir are considered in conjunction with geological conditions physical chemical characteristics. The results determinations were compared data isotopic analyses gases. Obtained indicate that thermal water weakly radioactive ( 222 Rn < 130 Bq/l) contain not exceeding norms for drinking (U<15 μg/l). altitude springs above sea level, as well δ 18 O content waters, shown to be connected...
Abstract Studied waters belong to warm (T=30–50°C), alkaline (pH=8.9–9.3), low mineralized (TDS<235 mg/l) Na–HCO 3 or Na–SO 4 –HCO thermal with high content of SiO 2 (up 81 and F 3.9 mg/l), occur on modern volcano–tectonic rejuvenated areas Eastern Sikhote–Alin orogenic belt. Low He concentration as well N /O /Ar ratios exclude influence deep mantle fluid. New rare earth element data constrain our understanding water–rock interaction occurring in the water source region. Meteoric origin...
This study presents the first regional hydrogeochemical portrait of mineral waters and associated gases Central Asia region, shaped by Tien Shan Pamir. A geochemical survey more than 50 fluid discharges from Northern to Pamir was carried out between 2018 2019. Isotopic (δD, δ18O, d15N2, d13CCO2, d13CCH4) chemical data allow elucidating genesis general evolution in continental collision zone. Geothermometric estimations as well content components (Cl, Li, B, Br) (N2, CO2) suggest that studied...
Low-enthalpy thermal waters (30–70 °C) with nitrogen as a dominant associated gas are spread within the active continental margin of Russian Far East (east and north Okhotsk Sea Coast) traditionally great importance for recreation balneology facilities. The chemically classified into three groups: (i) Na–HCO3(SO4) type, low TDS (0.2 g/L) lowest temperature (<50 high pH (9.1–9.3), (ii) Na–SO4 type (~1 g/L), highest (70 weak alkaline (8.7) (iii) Ca–Na–Cl (15 moderate T (59 neutral (7.5)....
The behaviour of major ions and rare earth elements (REE) was studied in the hot springs volcano Mutnovsky (Kamchatka). We found that concentration REE depended on geochemical type water, with maximum content being Ca-SO4 waters. Overall, this study shows pH has a significant impact fractionation REE.
This article presents the new data on chemical and gas composition, content of stable isotopes oxygen, hydrogen, carbon, sulfur in natural mineral waters Essentuki field. A detailed study geological hydrogeological features water circulation area, its major organic matter water, temperature conditions δ18OSMOW, δDSMOW, δ13CDIC, δ18ODIC, δ34SVCDT, δ13CCO2, δ13CCH4, δ15N values made it possible to specify genesis gas, solute components CO2-rich The (δ18OSMOW δDSMOW) phase ranges from −13.75...
The article presents new data on the ionic, microcomponent and isotopic composition of thermal waters Amga group classified as sodium-bicarbonate characterized by low mineralization (up to 0.2 g/l), high contents silica 24 mg/l), lithium, tungsten molybdenum, pH = 8.5–9.7. influence neotectonics Quaternary magmatism conditions formation nitrogen-siliceous is shown. Using δD δ18O values in background waters, their atmogenic origin was proved, source area mineral identified. calculated deep...
A small number of ecological-trophic groups bacteria are noted in saline groundwater’s (30-50 g/L). The obtained data show, that thionic and halophilic forms saprophytic dominated, developing presence 10% NaCl. Among microorganisms, rod-shaped the genus Microbacterium sp. significantly dominated. significant accumulation Cu, Co light REEs by brine microbial communities is shown.
