Underplating was originally proposed as the process of magma ponding at the base of the
crust and was inferred from petrologic considerations. This process not only may add high …

During the last four decades, subduction remained one of the most challenging and
captivating geodynamic processes investigated with numerical techniques. While significant …

Processes in subduction zones such as slab and mantle‐wedge metamorphism, intraslab
earthquakes, and arc volcanism vary systematically with the age‐dependent thermal state of …

Documenting the early tectonic and magmatic evolution of the Izu–Bonin–Mariana (IBM) arc
system in the Western Pacific is critical for understanding the process and cause of …

Subduction faults, called megathrusts, can generate large and hazardous earthquakes. The
mode of slip and seismicity of a megathrust is controlled by the structural complexity of the …

We review data and recent research on arc composition, focusing on the relatively complete
arc crustal sections in the Jurassic Talkeetna arc (south central Alaska) and the Cretaceous …

Andesite magmatism at convergent margins is essential for the differentiation of silicate
Earth, but no consensus exists as to andesite petrogenesis. Models proposing origin of …

Magmatic volatiles (for example, water) are abundant in arc melts and exert fundamental
controls on magma evolution, eruption dynamics and the formation of economic ore …

The Kyushu‐Palau Ridge (KPR) is a 2600 km long remnant island arc that is separated from
the active Izu‐Bonin‐Mariana (IBM) arc by a series of spreading and rift basins. We present …

Intra-oceanic arc systems (IOASs) represent the oceanic endmember of arc–trench systems
and have been the most important sites of juvenile continental crust formation for as long as …
