本文报道了哈巴罗夫斯克地区Mukhen矿床两种冷态高磷CO2地下水的水化学新数据。第一类为HCO3-Ca-Mg水体，TDS相对较低(可达1.7g/L)，Fe2+、Mn2+、Ba2+和SiO_2浓度较高。第二类为HCO3-Na组分，TDS高达14g/L，Li+、B、Sr2+、BR-−、I-−升高。关于水域的新的氧(δ18O)和氢(δD)同位素数据和关于气相的碳(δ13C)同位素数据，加上对研究区的详细地质和水文地质分析，使我们能够破译这两种矿泉水的来源。根据该地区地下水和地表水中的氚含量，估计了矿泉水循环的持续时间。结果表明，这两类地下水都是大气降水与基岩在CO2的活跃影响下相互作用形成的，但HCO3-Na地下水比HCO3-Ca-Mg地下水具有更长的停留时间。
This work reports new hydrochemical data on the two types of cold high p CO2groundwaters from the Mukhen deposit (Khabarovsk district). The first type is classed with HCO3-Ca-Mg waters with a relatively low TDS (up to 1.7 g/l) and high concentrations of Fe2+, Mn2+, Ba2+, and SiO2. The second type is of HCO3-Na composition with high TDS (up to 14 g/l) and elevated Li+, B, Sr2+, Br−, and I−. New oxygen (δ18O) and hydrogen (δD) isotopic data on the waters and carbon (δ13C) isotopic data on the gas phase, together with a detailed geological and hydrogeological analysis of the study area, allowed us to decipher the origin of both the mineral waters. Based on the tritium content (3H) in the ground and surface waters of the area, the duration of the mineral water circulation was estimated. It was established that the both types of groundwaters were formed during interaction of meteoric water with bedrock under active influence of CO2, however HCO3-Na groundwaters have longer residence time than HCO3-Ca-Mg groundwaters.
