The Raikoke Volcanic Massif, Kuril Island Arc

Journal of Volcanology and Seismology, 2021
This study is concerned with the Raikoke volcanic massif, part land, part undersea, situated in the northern Central Kuriles. It consists of Raikoke volcano-island and the Quaternary undersea volcano 3.18. The eruption of June 2019 did considerable damage to the fauna and flora of Raikoke Island, changing its aspect one more time.

Geochemistry of Thermal Waters of Ketoi Island, Kuril Island Arc

Journal of Volcanology and Seismology, 2018
The data obtained during the fieldworks in July 2016 were used for the geochemical description of thermal manifestations of Ketoi and Pallas Peak volcanoes on Ketoi Island in the middle of the Kuril Island arc. It is shown that the older edifice of Ketoi Volcano hosts a high temperature hydrothermal system whose surface manifestations are concentrated ...

Kurile island-arc volcanism: structural and petrological aspects

Tectonophysics, 1991
Abstract This study discusses the structural and spatial characteristics of all known Kurile island-arc Quaternary volcanoes, which include 105 that are subaerial and 96 submarine. Volcanic activity in the island arc is distributed in two zones parallel to the Kurile-Kamchatka deep-sea trench. The depth to the seismo-focal zone in the frontal zone is

Mineralogy, geochemistry and petrogenesis of Kurile island-arc basalts

Contributions to Mineralogy and Petrology, 1989
Whole-rock (major- and trace-element) and mineral chemical data are presented for basaltic rocks from the main evolutionary stages of the Kurile island arc, NW Pacific. An outer, inactive arc contains a Cretaceous-Lower Tertiary sequence of tholeiitic, calcalkaline and shoshonitic basalts.

Geochemistry of late Cenozoic lavas on Kunashir Island, Kurile Arc

Island Arc, 2010
AbstractMiddle Miocene to Quaternary lavas on Kunashir Island in the southern zone of the Kurile Arc were examined for major, trace, and Sr–Nd–Pb isotope compositions. The lavas range from basalt through to rhyolite and the mafic lavas show typical oceanic island arc signatures without significant crustal or sub‐continental lithosphere contamination ...

Petrochemical variations of island arc andesites (Kurile Island Arc)

Journal of Geophysical Research: Solid Earth, 1988
The problem of comparison of island arc andesites in terms of petrochemical data is examined. It has been proved that in the case of the Kurile Arc, two main factors exist governing the petrochemical variety of andesites. We have made use of original multivariate statistical techniques and computer software to extract these factors.
