For the first time, a detailed description of springs with alkaline waters (pH > 10) found within the ultrabasic massif of the Mt. Soldatskaya on the Kamchatsky Mys Peninsula in Kamchatka is presented. The chemical composition of the springs and the dependence of the ratios and concentrations of some components on pH correspond to the formation of these waters due to modern serpentinization of ultramafic rocks. The most alkaline springs (pH 12.3) contain dissolved hydrogen at a concentration of about 0.6 mmol/l. The behavior of the isotopic composition of carbonate travertines precipitated from these springs (δ13C and δ18O) differs from the known trend for “meteogenic” travertines, associated with serpentinization of ultrabasic rocks in Oman and California. The age of travertines, determined by the radiocarbon method is close to the modern.
