Discovery of coesite, diamond, and extreme 18O-depletion in eclogites from the Dabie–Sulu
orogen in central-east China has contributed much to our understanding of subduction of …

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

Crust extracted from the mantle in arcs is refined into continental crust in subduction zones.
During sediment subduction, subduction erosion, arc subduction, and continent subduction …

High-P/T metamorphic belts were classified into types A and B according to their protoliths.
The A-type (collision-type) blueschists possess passive-margin protoliths characterized by …

The phase and melting relations in subducted pelites have been investigated experimentally
at conditions relevant for slabs at sub-arc depths (T= 600–1050° C, P= 2· 5–4· 5 GPa). The …

More and more evidence is being discovered in Phanerozoic collision belts of the burial of
crustal rocks to previously unsuspected (and ever increasing) depths, presently on the order …

Diamondiferous rocks from the Kokchetav Massif, Kazakhstan, represent deeply subducted
continental crust. In order to constrain the age of ultra high pressure (UHP) metamorphism …

We report here the first discovery of ultrahigh-pressure (UHP) indicator minerals and
textures from the Rhodope Metamorphic Province (RMP), northern Greece. In particular, we …

Phengite chemistry has been investigated in experiments on a natural SiO 2–TiO 2-
saturated greywacke and a natural SiO 2–TiO 2–Al 2 SiO 5-saturated pelite, at 1.5–8.0 GPa …

Intracontinental collisional belts that retain mineralogic relics of Phanerozoic ultrahigh-
pressure (UHP) metamorphism are increasingly being recognized. Adjacent regions …
