First data on magma ascent and residence times retrieved from Fe-Mg and trace element zonation in olivine phenocrysts from Kamchatka basalts

Gordeychik Boris; Churikova Tatiana; Kronz Andreas; Simakin Alexander; Wörner Gerhard (2016-04-16)

Compositional zonation in olivine phenocrysts and diffusion modelling have been used in the last ten years to estimate magma residence times and the duration of magma ascent. The fundamental assumption is that mixing with ...
Geochemical evolution of Bolshaya Udina, Malaya Udina, and Gorny Zub volcanoes, Klyuchevskaya Group (Kamchatka)

Churikova Tatiana; Gordeychik Boris; Wörner Gerhard; Flerov Gleb; Hartmann Gerald; Simon Klaus (2017-04)

The Klyuchevskaya group of volcanoes (KGV) located in the northern part of Kamchatka has the highest magma production rate for any arc worldwide and several of its volcanoes have been studied in considerable detail [e.g. ...
Mineral Resources of the Geothermal Sources of the North Caucasus

Mintsaev Magomed; Machigova Fatima; Khadasheva Zulai; Cherkasov Sergei; Churikova Tatiana (2016)

The growth in the world consumption of raw materials resources accompanied by depletion of ore deposits explains the interest of many countries in the mineral potential of thermal waters. The Russian Federation has vast ...
Olivine zoning in high-Mg basalts of the Shiveluch volcano (Kamchatka)

Gordeychik Boris; Churikova Tatiana; Kronz Andreas; Simakin Alexander; Wörner Gerhard (Copernicus Publications, 2017)

Shiveluch volcano located in northern Kamchatka erupted mainly high-Mg andesites during Holocene times. However, tephrochronologists found two Holocene tephra layers that are unusual for this volcano: a high-Mg middle-K ...
Origin of monogenetic volcanoes of NE Kamchatka: constraints from mineral compositions

Nishizawa Tatsuji; Nakamura Hitomi; Iwamori Hikaru; Churikova Tatiana; Gordeychik Boris; Ishizuka Osamu (The Volcanological Society of Japan, 2015-09-28)
Petrological and chronological study of primitive high-Mg andesite from monogenetic volcanoes in the fore-arc region of northern Kamchatka Peninsula

Nishizawa Tatsuji; Nakamura Hitomi; Churikova Tatiana; Gordeychik Boris; Ishizuka Osamu; Iwamori Hikaru (Hokkaido University, 2014-09-22)

Primitive high-Mg andesites (HMA) exhibit low FeO*/MgO (FeO*, total iron) and high Mg# (=100×Mg/(Mg+Fe)), and are thought to be generated by hydrous mantle melting (Kushiro, 1969). HMA, including sanukitoids of the Setouchi ...
Petrological study of monogenetic volcanoes in the fore-arc region of the northern Kamchatka Peninsula

Nishizawa Tatsuji; Churikova Tatiana; Gordeychik Boris; Ishizuka Osamu; Nakamura Hitomi; Iwamori Hikaru (Japan Geoscience Union, 2014-04-28)

The western part of the Pacific Plate is subducting under the Okhotsk Plate along Kuril-Kamchatka Trench, and the northern part of it is subducting under the Bering Sea Plate with high obliquity along the western Aleutians ...
Petrology and geochemistry of the Tolbachik stratovolcano

Churikova Tatiana; Gordeychik Boris; Iwamori Hikaru; Nakamura Hitomi; Nishizawa Tatsuji; Haraguchi Satoru; Yasukawa Kazatuka; Ishizuka Osamu (Hokkaido University, 2014-09-22)

The numerous of national and international publications were dedicated to Plosky Tolbachik volcano eruptions and adjacent monogenetic cones, which were erupted repeatedly during Holocene, including historical time [i.e. ...
Slab-mantle thermal structure beneath northeast Kamchatka Peninsula constrained from high-Mg basalts and andesites

Nishizawa Tatsuji; Nakamura Hitomi; Churikova Tatiana; Gordeychik Boris; Ishizuka Osamu; Iwamori Hikaru (Japan Geoscience Union, 2015-05-24)
Stratigraphy, structure and geology of Late Miocene Verkhneavachinskaya caldera with basaltic–andesitic ignimbrites at Eastern Kamchatka

Bergal-Kuvikas Olga; Leonov Vladimir; Rogozin Aleksei; Bindeman Ilya; Kliapitskiy Evgeniy; Churikova Tatiana (2019)

We newly describe a paleovolcano in the Eastern Volcanic Belt of Kamchatka named Verkhneavachinskaya caldera (VC). According to geological mapping of the area covered by the deposits, mainly lava-like ignimbrites, the VC ...
Volatile (S, Cl and F) and fluid mobile trace element compositions in melt inclusions: implications for variable fluid sources across the Kamchatka arc

Churikova Tatiana; Wörner Gerhard; Mironov Nikita; Kronz Andreas (2007)

Volatile element, major and trace element compositions were measured in glass inclusions in olivine from samples across the Kamchatka arc. Glasses were analyzed in reheated melt inclusions by electron microprobe for major ...
カムチャッカ北東端の単成火山の成因: 鉱物組成からの制約

西澤達治; 中村仁美; 岩森光; Churikova Tatiana; Gordeychik Boris; 石塚治 (The Volcanological Society of Japan, 2015-09-28)
カムチャツカ半島北部, 火山フロントの海溝側に分布する未分化な単成火山群の岩石学的研究

西澤達治; Churikova Tatiana; Gordeychik Boris; 石塚治; 中村仁美; 岩森光 (Japan Geoscience Union, 2014-04-28)

太平洋プレートの西部は、千島－カムチャツカ海溝からオホーツクプレート下に沈み込んでおり、北部はアリューシャン海溝からベーリング海プレート下に斜めに沈み込んでいる。両者はカムチャツカ半島中部で交わり、三重会合点を形成している（Eichelberger et al., 2013）。太平洋プレートの北端はトランスフォーム断層になっており、マントルウェッジが北（ベーリング海方向）に向かって開いていると予想される。カムチャツカ半島には少なくとも29 ...
高 Mg 玄武岩―安山岩から制約するカムチャツカ北東部のスラブとマントルの温度構造

西澤達治; 中村仁美; Churikova Tatiana; Gordeychik Boris; 石塚治; 岩森光 (Japan Geoscience Union, 2015-05-24)
