The kinematics of subduction zones shows a variety of settings that can provide clues for
dynamic understandings. Two reference frames are used here to describe the simple 2D …

Subduction processes are central to plate tectonics and to crust–mantle recycling and
differentiation. Here we present a study of lavas from the Tonga–Kermadec island arc which …

Rare earth element (REE) and yttrium (Y) concentrations were measured in fluids collected
from deep-sea hydrothermal systems including the Mid-Atlantic Ridge (MAR), ie, Menez …

The discovery of metal-depositing hot springs on the sea floor, and especially their link to
chemosynthetic life, was among the most compelling and significant scientific advances of …

The relationship between subduction and back‐arc spreading has been well known since
the early days of plate tectonics. However, the reasons why back‐arc basins are associated …

The highly depleted intra-oceanic Tonga-Kermadec island arc forms an endmember of arc
systems and a unique location in which to isolate the effects of the slab flux. High precision …

A variety of atypical plume-like structures and focused upwellings that are not rooted in the
lower mantle have recently been discussed, and seismological imaging has shown …

Recent results of high-resolution seismic tomography and mineral physics experiments are
used to study mantle dynamics of Western Pacific and East Asia. The most important …

Crustal anatectites are frequently observed along ocean–continent active margins, although
their origins are disputed with interpretations varying between rift-related and collisional. We …

The age of spreading of the Liguro–Provençal Basin is still poorly constrained due to the
lack of boreholes penetrating the whole sedimentary sequence above the oceanic crust and …
