Dorendorf Frank, Wiechert Uwe, Wörner Gerhard Hydrated sub-arc mantle: a source for the Kluchevskoy volcano, Kamchatka/Russia // Earth and Planetary Science Letters. 2000. Vol. 175. № 1–2. P. 69 - 86. doi: 10.1016/S0012-821X(99)00288-5.
Oxygen isotope ratios of olivine and clinopyroxene phenocrysts from the Kluchevskoy volcano in Kamchatka have been studied by CO2 and ArF laser techniques. Measured δ18O values of 5.8–7.1‰ for olivine and 6.2–7.5‰ for clinopyroxene are significantly heavier than typical mantle values and cannot be explained by crustal assimilation or a contribution of oceanic sediments. Positive correlations between δ18O and fluid-mobile elements (Cs, Li, Sr, Rb, Ba, Th, U, LREE, K) and a lack of correlation with fluid-immobile elements (HFSE, HREE) suggest that 18O was introduced into the mantle source by a fluid from subducted altered oceanic basalt. This conclusion is supported by radiogenic isotopes (Sr, Nd, Pb). Mass balance excludes simple fluid-induced mantle melting. Instead, our observations are consistent with melting a mantle wedge which has been hydrated by 18O-rich fluids percolating through the mantle wedge. 18O-enriched fluids are derived from the subducted oceanic crust and the Emperor seamount chain, which is responsible for a particularly high fluid flux. This hydrated mantle wedge was subsequently involved in arc magmatism beneath Kluchevskoy by active intra-arc rifting.

Изучение магматических питающих систем вулканов, корней вулканов, является одной из основных задач вулканологии. К числу главных объектов таких исследований принадлежит Ключевская группа вулканов (КГВ) наиболее мощная на островных дугах и в зонах поддвига литосферных плит. Сообщается о всесторонних исследованиях, которые ведутся здесь с 1931 г. Приводится ряд показательных результатов, полученных с 1960-х годов при изучении источников магм, извержений, землетрясений, деформаций и глубинного строения КГВ. При их рассмотрении учитываются данные физической вулканологии о механизме вулканической деятельности и данные петрологии о формировании магм. В магматической питающей системе КГВ и ее геофизической модели выделяются следующие пять частей: источник энергии и вещества у верхней границы тихоокеанского сейсмофокального на глубине около 160 км, область подъема магм в астеносфере, область накопления магм в коромантийном слое на глубинах 40-25 км, магматические очаги и каналы в земной коре, основания построек вулканов. Рассматриваются и объясняются свойства, связь этих частей, механизм деятельности вулканов и магматической питающей системы КГВ в ее современном состоянии. Имеются способы расчета магматических каналов, очагов, количества магмы в системе и других ее свойств.

High-precision electron microprobe analyses were obtained on olivine grains from Klyuchevskoy, Shiveluch and Gorely volcanoes in the Kamchatka Arc; Irazu, Platanar and Barva volcanoes of the Central American Arc; and mid-ocean ridge basalt (MORB) from the Siqueiros Transform. Calcium contents of these subduction zone olivines are lower than those for olivines from modern MORB, Archean komatiite and Hawaii. A role for magmatic H2O is likely for subduction zone olivines, and we have explored the suggestion of earlier workers that it has affected the partitioning of CaO between olivine and silicate melt. We provide a provisional calibration of DCaO Ol/L as a function of magmatic MgO and H2O, based on nominally anhydrous experiments and minimally degassed H2O contents of olivine-hosted melt inclusions. Application of our geohygrometer typically yields 3–4 wt % magmatic H2O at the Kamchatka and Central American arcs for olivines having 1000 ppm Ca, which agrees with H2O maxima from melt inclusion studies; Cerro Negro and Shiveluch volcanoes are exceptions, with about 6% H2O. High-precision electron microprobe analyses with 10–20 lm spatial resolution on some olivine grains from Klyuchevskoy and Shiveluch show a decrease in Ca content from the core centers to the rim contacts, and a sharp increase in Ca in olivine rims. We suggest that the zoning of Ca in olivine from subduction zone lavas may provide the first petrological record of temporal changes that occur during hydration of the mantle wedge and dehydration during ascent, and we predict olivine H2O contents that can be tested by secondary ionization mass spectrometry analysis.

Kamchatka is one of the most active volcanic regions on the planet. Large explosive volcanic eruptions, in which the ash elevates up to 8–15 km above sea level, occur here every 1.5 years. Study of eruptions precursors in order to reduce a volcanic risk for the population is an urgent problem of Volcanology. The available precursor of strong explosive eruptions of volcanoes, identified from satellite data (thermal anomaly), as well as examples of successful prediction of eruptions using this precursor, are represented in this paper.
