Geochemistry and petrogenesis of volcanic rocks in the Kuril island arc

Petrology, 2010
Newly obtained precise analytical data on trace elements and radiogenic Sr, Nd, and Pb isotopes testify to anomalous geochemical characteristics of mafic and intermediate Quaternary lavas in Paramushir (in the north of the Kuril arc), Kunashir and Iturup (in the south) islands, which are the largest three islands of the Kuril island arc. The high K and

Magmatism of the submarine Vityaz Ridge (Pacific slope of the Kuril Island Arc) [PDF]

open access: yesOceanology, 2008
Original results of igneous rock studies are presented. The rocks were dredged during a marine expedition (cruise 37 of R/V Akademik M.A. Lavrent’ev in August–September, 2005) in the region of the submarine Vityaz Ridge and Kuril Arc outer slope. Several age complexes (Late Cretaceous, Eocene, Late Oligocene, Miocene, and Pliocene-Pleistocene) are ...

Geochemistry of granitoids from the basement of the Kuril island arc system

Geochemistry International, 2014
This paper reports the characteristics of granitoids from the Pacific slope of the Kuril island arc system, which were discovered by the authors during geological and geophysical operations in three cruises of the R/V Akademik M. Lavrent’ev. The major and trace element compositions of these rocks were determined, their role in the formation of the ...

The Rikord Submarine Volcanic Massif, Kuril Island Arc [PDF]

open access: yesJournal of Volcanology and Seismology, 2018
This paper reports a study of the Rikord volcanic massif. The massif consists of four volcanic edifices that coalesce in their bases, and is most likely Quaternary. The massif discharged basaltic and basaltic andesite lavas during its earlier life.

Patterns of the Seismic Cycle in the Kuril Island Arc from GPS Observations

Pure and Applied Geophysics, 2020
The 2006–2007 Simushir earthquakes started a new episode in the rupture history of the Kuril-Kamchatka subduction zone. This earthquake doublet terminated the seismic silence in the Central Kurils, which had lasted for almost a century. The analysis of seismologic, geologic and GPS data over the Kuril Islands region allows us to reveal the patterns of ...
