Quarterly Journal of the Geological Society of London, 1950
Summary Through geological time successive orogenic belts have shifted outward from central nuclei. Island arcs of the geosynclinal stage have often moved large distances in a horizontal direction. In the active zones of today movements continue, especially in association with the arcuate structure of the Pacific region, where the highest ...

Bulletin Volcanologique, 1980
Two major magma series are recognised in the northeastern Carribean island arcs and correlated with numerous examples elsewhere, mainly in the western Pacific. The Primitive Island Arc (PIA) series is apparently the oldest in each of its island-arc occurrences and is followed by the calcalkaline (CA) series, which locally co-occurs with a high ...

ARC-ARC COLLISION BY THE EXAMPLE OF THE ALEUTIAN AND KAMCHATKA ISLAND ARCS
Russian Geology and GeophysicsThis article presents data on active fault-related deformation of the Kamchatka Peninsula (Kamchatka, Russia), located between the converging Aleutian and Kamchatka Island arcs. It is shown that convergence of the arcs results in shortening of the Earth’s crust of the Kamchatka Peninsula in a direction transverse to the peninsula.

Continent — Island arc collision in the Banda Arc
Tectonophysics, 1979Abstract Acoustical structure of seismic profiles, and morphology of the Timor—Tanimbar—Ceram troughs and adjacent slopes of the outer Banda Arc, show remarkable similarities to equivalent parameters of many arcs subducting oceanic lithosphere and sediments, despite the fact that the outer Banda Arc is underlain by continental crust continuous with ...

Island arc elements and arc-related ophiolites
Tectonophysics, 1984Abstract All major structural elements in island arc systems, fore-arc, magmatic arc, back-arc basins and remnant arcs, are potential ophiolite sources, and those features that allegedly characterise ophiolites of ocean-ridge origin, sheeted dyke complexes, mantling pelagic rocks, hydrothermal metamorphism and associated mineralization, can also ...

Collision orogeny at arc‐arc junctions in the Japanese Islands
Island Arc, 1996Abstract In the Japanese Islands, collision tectonics are operating at arc‐arc junctions in three regions: Hokkaido, Central Japan and Kyushu. Hokkaido is situated at the junction of the Kuril and Northeast Japan Arcs. The Kuril fore arc sliver collides with the Northeast Japan Arc, and the lower crust of the Kuril Arc thrusts upon the fore arc ...

Andaman Island Arc and Back-Arc Sea
2015The 850-km-long chain of islands between the Bay of Bengal and the Andaman Sea constitutes the central part of the 5000-km-long Myanmar–Indonesia Mobile Belt related to an active subduction zone. The Andaman Island Arc comprises two nearly parallel arcuate belts.

Geochemical Evidence for Island Arc Subduction Beneath the New Hebrides Island Arc
The tectonic history of the New Hebrides Island Arc (NHIA) is complex and characterized by collisions of oceanic plateaus, subduction interface rotation, as well as fragmentation and ultimately subduction polarity changes. Despite the intricate tecto-magmatic evolution of the NHIA, geochemical data are sparse and the geodynamic processes governing ...Nils B. Baumann +4 more
