One of the most contentious areas of Earth Science today is when, or whether or not modern-
style plate tectonics was in operation in the Archean Eon. In this review we present evidence …

Abstract The North China Craton (NCC) has been thinned from> 200 km to< 100 km in its
eastern part. The ancient subcontinental lithospheric mantle (SCLM) has been replaced by …

Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity.
However, crustal signatures in the mantle source of basaltic rocks above subduction zones …

Interactions between crustal and mantle reservoirs dominate the surface inventory of volatile
elements over geological time, moderating atmospheric composition and maintaining a life …

Global data for measured Fe 2 O 3/FeO ratios and Cu contents in unaltered volcanic and
intrusive arc rocks indicate that, on average, they are slightly more oxidized than other …

Subduction zones not only return oceanic lithosphere into the mantle, but are also sites
where chemical components are transferred from the downgoing plate back to the surface in …

Porphyry ore deposits are the source of much of the copper, molybdenum, gold and silver
used by humans. Porphyry ore typically forms in magmatic arcs above subduction zones …

Metals such as Cu, Mo, Au, Sn, and W in porphyry and related epithermal mineral deposits
are derived predominantly from the associated magmas, via magmatic–hydrothermal fluids …

Chemical geodynamics is an integrated discipline that studies the geochemical structure
and tectonic evolution of geospheres with the aim of linking tectonic processes to …

The transport of water from subducting crust into the mantle is mainly dictated by the stability
of hydrous minerals in subduction zones. The thermal structure of subduction zones is a key …
