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 …

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

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

Subduction is the main process that recycles surface material into the mantle. Fluids and
melts derived by dehydration and partial melting reactions of subducted continental crust, a …

The composition of continental subduction-zone fluids varies dramatically from dilute
aqueous solutions at subsolidus conditions to hydrous silicate melts at supersolidus …

Partial melting at continental lithosphere depths plays an important role in generating
geochemical variations in igneous rocks. In particular, dehydration melting of ultrahigh …

Phase and melting relations in deeply subducted sediments, the main reservoir of large ion
lithophile elements (LILE) in subduction zones, are of first order importance to understand …

Ultrahigh-pressure (UHP) metamorphism refers to mineralogical modifications of continental
and oceanic crustal protoliths±associated mafic-ultramafic rocks initially formed or emplaced …

Abstract The Dabie–Sulu orogenic belt in east-central China contains one of the largest
ultrahigh-pressure (UHP) metamorphic terranes in the world. The UHP eclogites are …

This review combines fluid inclusion data from (HP-) UHP rocks with experimental research
and thermodynamic models to investigate the chemical and physical properties of fluids …
