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 ...

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 ...

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 ...

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 ...
