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 ...

Churikova Tatiana G.; Gordeychik Boris N.; Ivanov Boris V.; Wörner Gerhard (2013)Abstract Data on the geology, petrography, mineralogy, and geochemistry of rocks from Kamen Volcano (Central Kamchatka Depression) are presented and compared with rocks from the neighbouring active volcanoes. The rocks ...
