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.

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 ...

Geochemistry of quaternary volcanic rocks from the Kurile-Kamchatka island arc

Journal of Volcanology and Geothermal Research, 1982
Abstract The distribution of trace and minor elements in Quaternary volcanic rocks of the Kurile-Kamchatka region was investigated. Studies carried out within this region made it possible to distinguish the rock series with low, moderate and high contents of K, Rb, Be, La and other lithophile elements.

SPECIFIC FEATURES OF RECENT TECTONISM ALONG THE KURIL ISLANDS ARC

International Geology Review, 1962
Recent movements, volcanism, seismology, gravimetry and deep seismic sounding data along the belt of the Kuril Islands are considered. It is established that the central portion of the arc, restricted by the Bussol and Krusenstern strait fractures, is characterized by a high speed of recent downwarpings, still increased by recent volcanic activity, and

Tectonic stress accumulation in the region of the Kuril–Kamchatka Island Arc system

Izvestiya, Physics of the Solid Earth, 2017
The time variations in the tidal response of the medium in 2011–2015 according to the measurements at the global seismographic network (GSN) in Kamchatka are considered. Based on the data from the horizontal pendulums recording the eastward tilts at the station, it is established that there was a linear growth in the tidal tilt amplitudes up to May 24,

Geochemistry of the submarine Vityaz Ridge at the pacific slope of the Kurile island arc

Geochemistry International, 2012
This paper reports the results of geological studies at the submarine Vityaz Ridge carried out during cruises 37 and 41 on the R/V “Akademik Lavrent’ev” in 2005 and 2006. The studied area is located at the near-island trench of the slope in the central part of the Kurile island arc.

Late Cainozoic explosive eruptions in the Aleutian and Kuril Island Arcs

Nature, 1975
THE rate at which major explosive eruptions have occurred in the Aleutian and Kuril Island Arcs is recorded in tephra layers recovered in cores of the Deep Sea Drilling Project (DSDP). Major tephra eruptions occurring with the frequency and intensity currently observed in the Aleutian and Kuril Arcs may have marked effects on world climate, especially ...

Petrochemical database for magmatic rocks from the inner Kurile island arc

Russian Journal of Pacific Geology, 2007
A petrochemical database newly developed for magmatic rocks from the Kurile island arc includes more than 2000 analyses, which were compiled from the literature, geological reports, and were made available for the author via personal communications.

Volcanism and the Upper Mantle: Investigations in the Kurile Island Arc

1970
The present volume seems to me to be a particularly im­ portant one for several reasons. Not least among these is the fact that it summarizes the work of two decades by G. S. Gorshkov, one of the world's leading volcanologists. In addition, it is the first general work of this length on the volcanism of what might be called a "narrow" island arc, a ...
