Neogene subduction initiation models in the western Pacific and analysis of subduction zone parameters
The Neogene is an important period for studying the onset of subduction, with numerous subduction zones forming in the western Pacific, including the...

Petrological and geochemical constraints of mantle peridotites on the magma-starved Yap Arc formed by ultra-slow subduction
Oceanic plateaus inevitably interact with trench–arc systems during oceanic subduction, but the subduction mechanisms are poorly understood. The Yap...

Subduction Zones, Island Arcs and Active Continental Margins
Subduction zones are created when two lithospheric plates move against each other and one of the two plates descends under the other through the...

Possible South-Dip** Mesozoic Subduction at Southern Tethys Ocean-Constrained from Global Tectonic Reconstructions and Seismic Tomography
The evolution of the Tethys Ocean involved several episodes of ocean opening (including the Paleo-Tethys and Neo-Tethys) along its southern margin as...

Molybdenum cycling in Andean-type subduction and metallogenic implications
We have conducted Mo isotope analyses of granites and related hydrothermal molybdenite from six Sn-W deposits in the western belt of the Southeast...

Geochemistry and geochronology of Middle Eocene subduction-related felsic volcanics in the Misis-Andirin Complex of the Southeast Anatolian Orogenic Belt
LA-ICP-MS zircon geochronology and geochemistry (whole-rock & mineral chemistry) from the Misis-Andirin Complex (MAC) volcanic rocks are reported....

Mountains and Plunging Plates: Subduction Zones
In subduction zones, oceanic crust plunges into the Earth’s mantle, with a chain of explosive volcanoes rising above. Such convergent plate...

Newly Identified A-type Granite in Western Yangtze Block and Its Geochemistry Characteristics: Evidence for Ridge Subduction beneath the South China Craton
AbstractNumerous Neoproterozoic granitic intrusions occur over a north-south distance of more than 700 km in the western Yangtze Block. In this...

Steep subduction of the Indian continental mantle lithosphere beneath the eastern Himalaya revealed by gravity anomalies
The geometry and deformation of the Indian continental mantle lithosphere (ICML) beneath the India-Eurasia collision zone are critical to...

Earthquake geology of the East Anatolian Fault and its participation in a devastating earthquake
This study revealed that the East Anatolian Fault and all of its fault segments including the Dead Sea transform have emerged as the most vulnerable...

Contact of the Samoan Plume with the Tonga Subduction from Intermediate and Deep-Focus Earthquakes
The Tonga subduction zone in the south-west Pacific is the fastest convergent plate boundary in the world with the most active mantle seismicity....

Mid-Cretaceous extensional magmatism in the Alborz Mountains, north Iran; geochemistry and geochronology of Gasht-Masuleh gabbros
In the Gasht-Masuleh area in the Alborz Mountains, gabbroic magma intruded Palaeozoic metasediments and Mesozoic sediments and crystallised as...

Geochronology and Geochemistry of Late Devonian I- and A-Type Granites from the **ng’an Block, NE China: Implications for Slab Break-off during Subduction of the Hegenshan-Heihe Ocean
We present detailed geochronological, geochemical, and zircon Hf isotopic data for Late Paleozoic granitic rocks from Handagai and Zhonghe plutons in...

Early Ordovician to early Silurian forearc accretionary processes in front of the Selety–Stepnyak arc in the Kokchetav area, northern Kazakhstan: implications for continental growth in the northwestern Altaids
In the Kokchetav area, a late Neoproterozoic to early Palaeozoic metamorphic, ophiolitic, and volcanic–sedimentary complex provides important...

Tectonic controls on the origin and segmentation of the Cascade Arc, USA
The magmatic response above subducting ocean lithosphere can range from weak to vigorous and from a narrow zone to widely distributed. The small and...

Yangshan A-Type Granites in the Lower Yangtze River Belt Formed by Ridge Subduction: Radiogenic Ca and Nd Isotopic Constraints
The Early Cretaceous aluminous A-type granites in the Lower Yangtze River belt (LYRB) can provide important insights into the Mesozoic magmatism in...

Rapid transition from MORB-type to SSZ-type oceanic crust generation following subduction initiation: insights from the mafic dikes and metamorphic soles in the Pozantı-Karsantı ophiolite, SE Turkey
The Pozantı-Karsantı ophiolite is one of the well-preserved supra-subduction-zone oceanic lithosphere slices. It offers a unique opportunity to study...
