Shiashkotan Island belongs to the Northern Kuril island arc and consists of two joined volcanoes, Sinarka and Kuntomintar, with about 18 km of distance between the summits. Both volcanoes are active, with historic eruptions, and both emit fumarolic gases. Sinarka volcano is degassing through the extrusive dome with inaccessible strong and hot (N400°C) fumaroles. A large fumarolic field of the Kuntomintar volcano situated in a wide eroded caldera-like crater hosts many fumarolic vents with temperatures from boiling point to 480°C. Both volcanoes are characterized by intense hydrothermal activity discharging acid SO 4 -Cl waters, which are drained to the Sea of Okhotsk by streams. At least 4 groups of near-neutral Na-Mg-Ca-Cl-SO 4 springs with temperatures in the range of 50-80°C are located at the sea level, within tide zones and discharge slightly altered diluted seawater. Volcanic gas of Kuntomintar as well as all types of hydrothermal manifestations of both volcanoes were collected and analyzed for major and trace elements and water isotopes. Volcanic gases are typical for arc volcanoes with 3 He/ 4 He corrected for air contamination up to 6.4 R a (R a = 1.4 × 10 −6 , the air ratio) and δ 13 C (CO 2 ) within −10‰ to −8 ‰ VPDB. Using a saturation indices approach it is shown that acid volcanic waters are formed at a shallow level, whereas waters of the coastal springs are partially equilibrated with rocks at~180°C. Trace element distribution and concentrations and the total REE depend on the water type, acidity and Al + Fe concentration. The REE pattern for acidic waters is unusual but similar to that found in some acidic crater lake waters. The total hydrothermal discharge of Cl and S from the island associated with volcanic activity is estimated at ca. 20 t/d and 40 t/d, respectively, based on the measurements of flow rates of the draining streams and their chemistry. The chemical erosion of the island by surface and thermal waters is estimated at 27 and 140 ton/km 2 /year, respectively, which is 2-3 times lower than chemical erosion of tropical volcanic islands.

“…10b), except for the waters of Group 1 where a strong positive anomaly (1.22-7.43) occurs, suggesting additional processes that fractionate the REE. The strong positive Eu anomaly found in the water of Group 1a could be justified by the slow interaction of waters with Eu enriched plagioclase, as already recognized in other hydrothermal systems (Wood, 2003 and references therein;Varekamp et al, 2009;Peiffer et al, 2011).…”

“…The REE abundances provide insight into water-rock interaction processes. The REE geochemistry in geothermal fluids is complex and depends on the pH, the stability of solid phases, the concentrations of anionic ligands complexing the REE and adsorption of mineral surfaces (Wood, 1990(Wood, , 2003Lewis et al, 1997Lewis et al, , 1998, and references therein; Gammons et al, 2005;Bao et al, 2008;Peiffer et al, 2011). The concentration of total dissolved REE in near neutral pH waters and in seawater is low and their dissolved species are dominated by carbonate complexes (Byrne, 2002), whereas in acidic waters (pH b 3.6) carbonate and hydroxide can be considered negligible.…”

Ebeko volcano at the northern part of Paramushir Island in the Kuril island arc produces frequent phreatic eruptions and relatively strong fumarolic activity at the summit area~1000 m above sea level (asl). The fumaroles are characterized by low-temperature, HCl-and S-rich gas and numerous hyper-acid pools (pH b 1) without drains. At~550 m asl, in the Yurieva stream canyon, many hot (up to 87°C) springs discharge ultra-acidic (pH 1-2) SO 4 -Cl water into the stream and finally into the Sea of Okhotsk. During quiescent stages of degassing, these fumaroles emit 1000-2000 t/d of water vapor, b 20 t/d of SO 2 and b 5 t/d of HCl. The measurement of acidic hot Yurieva springs shows that the flux of Cl and S, 60-80 t/d each, is independent on the volcanic activity in the last two decades. Such high flux of Cl is among the highest ever measured in a volcano-hydrothermal system. Oxygen and hydrogen isotopic composition of water and Cl concentration for Yurieva springs show an excellent positive correlation, indicating a mixing between meteoric water and magmatic vapor. In contrast, volcanic gas condensates of Ebeko fumaroles do not show a simple mixing trend but rather a complicated data suggesting evaporation of the acidic brine. Temperatures calculated from gas compositions and isotope data are similar, ranging from 150 to 250°C, which is consistent with the presence of a liquid aquifer below the Ebeko fumarolic fields. Saturation indices of non-silicate minerals suggest temperatures ranging from 150 to 200°C for Yurieva springs. Trace elements (including REE) and Sr isotope composition suggest congruent dissolution of the Ebeko volcanic rocks by acidic waters. Waters of Yurieva springs and waters of the summit thermal fields (including volcanic gas condensates) are different in Cl/SO 4 ratios and isotopic compositions, suggesting complicated boiling-condensationmixing processes.
