Neoproterozoic tectonic geography was dominated by the formation of the supercontinent
Rodinia, its break-up and the subsequent amalgamation of Gondwana. The Neoproterozoic …

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 …

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

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

Whenever a mineral or mineral assemblage comes into contact with a fluid with which it is
out of equilibrium, reequilibration will tend to take place to reduce the free energy of the …

Ubiquitous heterogeneity in the Earth's mantle has been documented by numerous
chemical and isotopic analyses of oceanic basalts. Despite the ever-increasing amount of …

The origin of the Antarctic continent can be traced to a relatively small late Archaean cratonic
nucleus centred on the Terre Adélie regions of East Antarctica and the Gawler Craton region …

High-pressure (HP) and ultra-high pressure (UHP) terranes are excellent natural
laboratories to study subduction-zone processes. In this paper we give a brief theoretical …

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

Geofluids (2010) 10, 254–269 Abstract Metamorphism and metasomatism both involve the
reequilibration of mineral assemblages due to changes in pressure, temperature and/or …
