The Components of the Glacial Runoff of the Tsambagarav Massif from Stable Water Isotope Data

Abstract: The aim of this study was to determine the contribution of snow and glacial ice to the river fluxes, and to identify the type of ice formation in the Tsambagarav massif (the northwestern part of Mongolia). The main method for this study was isotopic analysis of water samples. The isotopic separation showed that the shares of the main components in the total runoff differed for different rivers of the massif. Alongside with that, glacial meltwater prevailed in all the investigated fluxes. The share of snow and … Show more

“…The relationship between the relative content of 18 O and D in precipitation was determined by the fractionation coefficients of these isotopes. The formula of linear relationship between 18 O and D was obtained by H. Craig, and it has the following form:…”

“…Isotopic methods allow to carry out only two-component separation, i.e., to calculate the shares of the two most significant components in the total runoff can be calculated. This separation is carried out using the isotope balance formula, which generally has the form: R 18…”

“…Average annual air temperature is −5.6 • C, average winter −22.3 • C, average summer 16.5 and 16.6 • C; the average annual precipitation is 87 and 78 mm, respectively, with a predominance of the northwestern direction of moisture transfer [8]. The precipitation at the altitude of the firn boundary is estimated at about 270 mm [26]. Increase in precipitation with altitude, the position of the main watershed above the snow line, the predominance of flattened peaks as well as slope exposition and snowdrift transport are the main factors that determine the glaciation of the Tsambagarav ridge in such arid conditions.…”

“…However, this origin is difficult to reconcile with geotropic indications of a vadose environment. A third option is that the more depleted δ 18 O values were linked to the depletion of meteoric waters during glacial periods [93] with the concomitant increase of the relative elevation and distance of the Montjuïc Hill to the coast.…”
