Koloskov A.V., Flerov G.B., Perepelov A.B., Melekestsev I.V., Puzankov M.Yu., Filosofova T.M. The Evolutionary Stages and Petrology of the Kekuknai Volcanic Massif Reflecting the Magmatism in the Backarc Zone of the Kuril-Kamchatka Island Arc System. Part II. Petrologic and Mineralogical Features, Petrogenesis Model // Journal of Volcanology and Seismology. 2013. V. 7. № 2. P. 145-169. doi: 10.1134/S0742046313020048.    Аннотация
The Kekuknai massif was formed in the course of tectono-magmatic activity that involved the origin of a shield volcano and a caldera depression with associated emplacement of extrusions that terminated in intense post-caldera areal volcanism. The mineralogical compositions of the massifs rocks have been considered in detail. The use of previously known and newly developed indicator properties of rock-forming minerals allowed the reconstruction of the general picture of the magmatic melt evolution and conditions of rock crystallization (various fluid and water saturation levels, as well as the oxidation state of the system). Essentially island-arc or intraplate characteristics of the massif s rock compositions are found at different stages of development of a single fluid-magmatic system. Decompression evolution of the parent deep-seated basanitic magma occurred via occurrence in intermediate magma chambers of daughter magmas of trachybasalt (pre-caldera stage) or hawaiite (areal volcanism) composition. Subsequent emanate-magmatic differentiation of these melts, combined with crystallization differentiation under changing P-T-f0l conditions, resulted in the formation of the entire diversity of the Kekuknai rocks.

Кекукнайский массив сформировался в результате тектоно-магматической деятельности, выразившейся образованием щитообразного вулкана, кальдерной депрессии с сопутствующим внедрением экструзий, и завершившейся интенсивным посткальдерным ареальным вулканизмом. Проведено детальное рассмотрение особенностей минералогического состава пород массива. Использование уже имеющихся и дополнительно выявленных индикаторных возможностей породообразующих минералов позволило восстановить общую картину эволюции магматических расплавов и условия кристаллизации пород (различная флюидонасыщенность-обводненность и окисленность системы). Существенно островодужные или внутриплитные характеристики в составе пород массива проявлены на разных стадиях развития единой флюидно-магматической системы. Декомпрессионная эволюция материнской глубинной базанитовой магмы была реализована появлением в промежуточных очагах дочерних магм трахибазальтового (докальдерный этап развития системы) или гавайитового (ареальный вулканизм) состава. Дальнейшая эманационно-магматическая дифференциация этих расплавов в сочетании с кристаллизационной дифференциации в условиях меняющейся P-T-f02 обстановки и привела к образованию всего многообразия пород Кекукнайского массива.

Uzon volcano caldera (Kamchatka): A unique natural laboratory of the present-day naphthide genesis // Russian Geology and Geophysics. 2011. V. 52. № 8.

Oil shows from the thermal springs of the Uzon volcano caldera have been studied by gas chromatography–mass spectrometry methods. Based on the composition and distribution of biomarker molecules, their genetic identity with the organic matter of Pliocene–Quaternary deposits has been established. It has been shown that the Uzon caldera is a unique natural laboratory of the present-day oil formation from the organic matter of Pliocene–Quaternary sediments. It has been stated that attempts to consider the compounds forming these oil shows as a product of hydrothermal abiogenic synthesis are absolutely unfounded.

Abstract—We discuss the water!level variations in the E!1 well for the time period between May 2006 and
2010, inclusive. A trend towards an increasing level at an abnormally high rate occurred from mid!2006 to
December 2009. This increase is regarded as the response of the aquifer of gas!saturated ground water that
exists in the volcanogenic–sedimentary deposits of the Avacha volcano!tectonic depression to volumetric
strain changes during the precursory period and the occurrence of a swarm of small earthquakes ( = 8.3)
in the area of Koryakskii Volcano and to its phreatic eruption. We estimated the volumetric compression as
Δε = –(4.1 × 10–6–1.5 × 10–5) from the amplitude of water!level rise using the elastic parameters of the wa!
ter!saturated rocks. While the strain source was active, we observed a decreasing sensitivity of the hydrologic
regime in the well to the precursory processes before large (M ≥ 5.0) tectonic earthquakes.

We present the results of time-dependent local earthquake tomography for the Kluchevskoy group of volcanoes in Kamchatka, Russia. We consider the time period from 1999 to 2009, which covers several stages of activity of Kluchevskoy and Bezymianny volcanoes. The results are supported by synthetic tests that recover a common 3D model based on data corresponding to different time windows. Throughout the period, we observe a robust feature below 25 km depth with anomalously high Vp/Vs values (up to 2.2). We interpret this feature as a channel bringing deep mantle materials with high fluid and melt content to the bottom of the crust. This mantle channel directly or indirectly determines the activity of all volcanoes of the Kluchevskoy group. In the crust, we model complex structure that varies over time. During the pre-eruptive period, we detected two levels of potential magma storage: one in the middle crust at 10–12 km depth and one close to the surface just below Kluchevskoy volcano. In 2005, a year of powerful eruptions of Kluchevskoy and Besymiyanny volcanoes, we observe a general increase in Vp/Vs throughout the crust. In the relaxation period following the eruption, the Vp/Vs values are generally low, and no strong anomalous zones in the crust are observed. We propose that very rapid variations in Vp/Vs are most likely due to abrupt changes in the stress and deformation states, which cause fracturing and the active transport of fluids. These fluids drive more fracturing in a positive feedback system that ultimately leads to eruption. We envision the magma reservoirs beneath the Kluchevskoy group as sponge-structured volumes that may quickly change the content of the molten phases as fluids pulse rapidly through the system.

Avacha group includes two active and potentially dangerous volcanoes, Avachinsky and Koryaksky, located close to Petropavlovsk-Kamchatsky, the main city of Kamchatka. We present the results of two independent seismic studies of shallow crustal structures beneath the Avacha group based on passive and active source observations. The first study is based on the analysis of continuous recording by 11 seismic stations installed over the Avacha group in 2012 and 7 permanent stations in the same region. We present a series of 2D Rayleigh-wave group velocity maps based on correlation of ambient noise, that were then converted into 3D distribution of shear wave velocity. The second work was based on the reprocessing of an active source deep seismic sounding profile across the Avachinsky volcano that was shot in 1982–1984. We made the analysis of travel times of refracted waves using a 2D tomography inversion. The resulting seismic models appear to be consistent with each other and show clear low-velocity zone to the SW of the Avachinsky volcano and high velocity structures to NE. These observations also agree with the existing gravity and magnetotelluric measurements. Based on the obtained seismic models we identify two large buried calderas and large lava flows that are thought to be related to a series of large eruption episodes of Avachinsky occurred within the last 30,000 years.

Abstract A new fissure eruption began on 27 November 2012 on the southern slope of Plosky Tolbachik volcano, which is located in central Kamchatka, Russia, and is part of the Klyuchevskoy volcano group. We analyzed the displacement of the earth surface and the seismicity during several months before the eruption onset. According to seismic and GPS data the eruption was preceded by about 4–5 months (July–November 2012) of synchronous crustal deformation and seismicity. The seismic anomaly comprises low energy level seismicity (mainly M = 1.2–2.3) under Plosky Tolbachik volcano at a depth of less than 5 km. In the 2–3 weeks immediately preceding the eruption the rate of seismicity and the amount of radiated seismic energy exceeded the long-term average values (2000–2011) by more than 40 times. The deformation anomaly was recorded by displacement of the GPS points at distances from 20 to 60 km to the north of Tolbachik. The principal axis of the compressive strain was approximately directed towards the Tolbachik eruption site. The permanent GPS network detected radial compression and tangential stretching. The compressive strain reached about 10− 7 prior to eruption onset. The comparable duration of seismic and deformation anomalies (~ 4–5 months before the eruption) is consistent with a common origin, connected to magma rising from depth, and is interpreted as indicating that they were medium-term precursors to the eruption. Data recorded during this unrest episode of the Tolbachik volcanic zone will contribute to understanding of the reawakening of volcanic activity in this region and others worldwide with similar characteristics.

Большая часть Камчатки покрыта почвенно-пирокластическим чехлом, который представляет собой непрерывно накапливающийся "слоёный пирог", состоящий из горизонтов тефры и погребенных почв. Пеплы крупнейших извержений образуют чёткие маркирующие прослои во вмещающих отложениях, которые прослеживаются на огромных территориях. Толща между маркирующими прослоями пеплов имеет также пирокластическую природу и включает как продукты менее мощных или дальних извержений, так и вторично переотложенные пеплы [2]. В данной работе представлены результаты исследования физико-химических свойств вулканических пеплов, представленных как пеплами-маркерами, так и неопознанной тефрой.
В работе использовались следующие экспериментальные методы исследования:
- гранулометрический состав определялся пипеточным методом (ГОСТ…).
- теплопроводные характеристики вулканических пеплов определяли методом регулярного режима I рода [7].
- фазовый состав влаги и температура начала замерзания определялись криоскопическим и контактным методами [7].
- минеральный анализ определен на ИК-спектрометре ФСМ-1201 (Россия) в интервале 400-4000 cм-1 при комнатной температуре. Спектральное разрешение составляло 2,0 cм-1, абсолютная калибровочная ошибка волнового числа - не больше ±0,1 cм-1 [6]. Состав стекол этих пеплов был проанализирован на микрозонде "Jeol JSM-6480LV", энергодисперсионным спектрометром "INCA-Energy 350" (окно ATW-2) в Лаборатории локальных методов исследования вещества МГУ.
Были исследованы образцы вулканического пепла, отобранные в районе Ключевской группы вулканов и в долине р. Камчатка, в диапазоне высот 129-1650 м. Почти все пеплы относятся к голоценовым, за исключением образца, отобранного из отложений озерных диатомовых глин яра Половинка в долине р. Камчатки, возраст которых относится ко второй половине раннего плейстоцена (Q21). Образец представляет собой белый рыхлый витрокластический пепел кислого состава.
Согласно ГОСТ 25100-95 по гранулометрическому составу вулканические пеплы относятся к пескам пылеватым. По содержанию SiO2 вулканическое стекло исследуемых пеплов относится к трем типам: риолитовый, андезитовый и базальтовый. Согласно данным ИК-спектроскопии в камчатских пеплах с андезитовым и базальтовым стеклом был найден аллофан, с риолитовым стеклом - опал (аллофан - аморфный слоистый алюмосиликат, опал - минерал подкласса гидроксидов, не является глинистым минералом).
Получены следующие результаты исследования физ.-хим. свойств рассматриваемых пеплов.
Фазовый состав влаги. Впервые в наших исследованиях был получен фазовый состав влаги (т.е. содержание льда, незамерзшей воды и пара) в мерзлых вулканических пеплах Камчатки (ссылки на наши работы). Наиболее важная характеристика фазового состава влаги в мёрзлой породе - зависимость содержания незамерзшей воды Ww от температуры t. Экспериментально установлены зависимости содержания незамерзшей воды от температуры для мёрзлых вулканических пеплов в диапазоне температур от 0 до -15 оС, содержание Ww при температуре ниже -3 оС изменяется незначительно. Установлено, что, например, при температуре определения теплофизических характеристик -10оС в исследуемых образцах содержание незамерзшей воды изменяется от 0 до 11%. Это связано с преобразованием вулканического стекла и появлением глинистых минералов (аллофанов). Последние характеризуются большой удельной поверхностью, что и определяет появление разного количества незамерзшей воды.
Теплопроводные свойства. Получены экспериментальные данные по изучению теплопроводности вулканических пеплов для талого и мерзлого состояния в широком диапазоне влажности и плотности (ссылки на наши работы). При изменении влажности от 0 до 78% и плотности скелета ?d от 0,7 до 1,7 г/см3 коэффициент теплопроводности ? закономерно увеличивается от 0,13 до 1,0 Вт/(м·К) в талом и от 0,14 до 1,27 Вт/(м·К) в мерзлом состоянии. При этом не смотря на то, что вулканические пеплы по гранулометрическому составу относятся к пескам пылеватым, они очень сильно отличаются от последних. Так, сравнение данных по теплопроводности для вулканогенно-обломочных и осадочных дисперсных пород показало, что вулканические дисперсные породы имеют очень низкую теплопроводность как в талом, так и в мерзлом состоянии, что объясняется многими причинами, например, разностью теплопроводностей скелета пород (теплопроводности кварца и вулканического стекла отличаются в 3-4 раза), так и формой самих частиц.
Засоленность. Анализ засоленности пеплов показал, что по ГОСТ 25100-95 все исследованные пеплы, за исключением образца, отобранного из яра Половинка, относятся к незасоленным, суммарное содержание легкорастворимых солей в них около 0,02-0,03%; пепел из яра относится к сильно засоленным. По результатам химического анализа водной вытяжки этого пепла сумма солей составляет 1,815% от массы вещества, а по химическому составу представлена преимущественно сульфатами (содержание SO42- составляет 1,242% от массы вещества). Также отмечено очень низкое pH=3,4.

Kamchatka Peninsula is one of the most active volcanic regions in the world. Many Holocene explosive eruptions have resulted in widespread dispersal of tephra-fall
deposits. The largest layers have been mapped and dated by the 14C method. The tephra provide valuable stratigraphic markers that constrain the age of many geological
events (e.g. volcanic eruptions, palaeotsunamis, faulting, and so on). This is the first systematic attempt to use electron microprobe (EMP) analyses of glass to characterize
individual tephra deposits in Kamchatka. Eighty-nine glass samples erupted from 11 volcanoes, representing 27 well-identified Holocene key-marker tephra layers, were analysed. The glass is rhyolitic in 21 tephra, dacitic in two, and multimodal in three.
Two tephra are mixed with glass compositions ranging from andesite/dacite to rhyolite. Tephra from the 11 eruptive centres are distinguished by their glass K2O,
CaO, and FeO contents. In some cases, individual tephra from volcanoes with multiple eruptions cannot be differentiated. Trace element compositions of 64 representative
bulk tephra samples erupted from 10 volcanoes were analysed by instrumental neutron activation analysis (INAA) as a pilot study to further refine the geochemical haracteristics; tephra from these volcanoes can be characterized using Cr and Th contents and La/Yb ratios.
Unidentified tephra collected at the islands of Karaginsky (3), Bering (11), and Attu (5) as well as Uka Bay (1) were correlated to known eruptions. Glass compositions and
trace element data from bulk tephra samples show that the Karaginsky Island and Uka Bay tephra were all erupted from the Shiveluch volcano. The 11 Bering Island tephra
are correlated to Kamchatka eruptions. Five tephra from Attu Island in the Aleutians are tentatively correlated with eruptions from the Avachinsky and Shiveluch volcanoes.

This paper presents results from a study of lava flows that were discharged by Bezymyannyi Volcano at different times, from old (about 3500 years ago) to recent ones (1985–1989). We provide detailed descriptions of the composition, structure, and petrophysical properties for the main types of constituent rocks, which are andesites and basaltic andesites. It was found that porosity is the leading factor that controls rock properties, while the effects of structural and mineralogical features are less prominent. We demonstrate the variation in the properties of rocks that compose the lava flows in relation to their ages: the older a rock is, the higher its density and strength and the lower its porosity is.

Abstract A large dike intrusion and fissure eruption lasting 9 months began on November 27, 2013, beneath the south flank of Tolbachik Volcano, Kamchatka, Russia. The eruption was the most recent at Tolbachik since the Great Tolbachik Eruption from 1975 to 1976. The 2012 eruption was preceded by more than 6 months of seismicity that clustered beneath the east flank of the volcano along a NW–SE trend. Seismicity increased dramatically before the eruption, with propagation of the seismicity from the central volcano conduit in the final hours. We use interferometric synthetic aperture radar (InSAR) to compute relative displacement images (interferograms) for {SAR} data pairs spanning the eruption. We use satellite {SAR} data from the Canadian Space Agency's RADARSAT-2 and from the Italian Space Agency's COSMO-SkyMed missions. Data are modeled first through a Markov Chain Monte Carlo solution for a single tensile dislocation (dike). We then use a boundary element method that includes topography to model a distributed dike-opening model. We find the best-fitting dike dips 80° to the {WNW} with maximum opening of 6–8 m, localized in the near surface and more broadly distributed in distinct regions up to 3 km beneath the surface, which varies from 1 to 2 km elevation for the eruptive fissures. The distribution of dike opening and its correspondence with co-diking seismicity suggests that the dike propagated radially from Tolbachik's central conduit.

Two powerful eruptions of Quizapu vent on Cerro Azul Volcano, Chile are used as examples to discuss
the problem of effusive eruptions of magmas having high preeruptive volatile concentrations. A physicochemical
mechanism is proposed for magma degassing, with the volatiles being lost before coming to the surface.
The model is based on the interaction of magmas residing in chambers at different depths and on the difference
between the solubility of water in the melt and the water equilibrium concentration in a magma body
having a considerable vertical extent. The shallower chamber can accumulate the volatiles released from the
magma that is supplied from the deeper chamber. An explanation is provided of the dramatic differences in the
character of the 1846–1847 and 1932 eruptions, which had identical chemical–petrographic magma compositions.

На примере двух мощных извержений конуса Квицапу вулкана Сьерро-Ассуль (Чили) рассматривается проблема эффузивных извержений магм с высокими предэруптивными содержаниями летучих. Предложен физико-химический механизм дегазации магм с потерей ими летучих до появления на поверхности. Модель основана на взаимодействии магм, находившихся в разных по глубине очагах, и различии между растворимостью воды в расплаве и ее равновесной концентрацией в протяженном по вертикали магматическом теле. При этом малоглубинный очаг может аккумулировать летучие, выделяющиеся из магмы, поступающей в него из глубинного очага. Дается объяснение резких различий в характере извержений 1846–1847 и 1932 г. при идентичном химико-петрографическом составе магм.

The Sea of Okhotsk is the southernmost area in the Northern Hemisphere where seasonal sea ice is produced every year. The formation of sea ice drives thermohaline circulation in the Sea of Okhotsk, and this circulation supports the high productivity in the region. However, recent reports have indicated that sea-ice production in the Sea of Okhotsk is decreasing, raising concern that the decreased sea ice will affect not only circulation but also biological productivity in the sea. To reconstruct climatic changes in the Sea of Okhotsk region, we analyzed an ice core obtained from Ichinskaya Sopka (Mount Ichinsky), Kamchatka. We assumed that the remarkable negative peaks of δD in the ice core were caused by expansion of sea ice in the Sea of Okhotsk. Melt feature percentage (MFP), which indicates summer snowmelt, showed high values in the 1950–60s and the mid-1990s–2000s. The high MFP in the 1950–60s was assumed to be caused by an increase in cyclone activity reaching Kamchatka during a negative period of the Pacific Decadal Oscillation index, and that in the 1990–2000s may reflect the increase in solar irradiation during a positive period of the summer Arctic Oscillation index.
