Minerals included in diamonds provide direct information about the petrologic and chemical
environment of diamond crystallization. They record information relating to local and …

Determining the depth to which continental lithosphere can be subducted into the mantle at
convergent plate boundaries is of importance for understanding the long-term growth of …

When organisms adapt genetically to one environment, they may lose fitness in other
environments,,,. Two distinct population genetic processes can produce ecological …

Phase assemblages, melting relations and melt compositions of a dry carbonated pelite
(DG2) and a carbonated pelite with 1· 1 wt% H2O (AM) have been experimentally …

Phase relations in the natural pyrolitic mantle composition (KLB‐1) around 670‐km depth
have been determined at 1600–2200° C by high‐pressure experiments using multianvil …

Phase relationships in hydrated natural sediment and mid‐ocean ridge basalt (MORB)
compositions were investigated experimentally from 6 to 15 GPa and 700° C to 1400° C in …

Exsolution textures are observed in garnet and olivine crystals found in an orogenic garnet
peridotite massif in the North Qaidam ultrahigh-pressure metamorphic (UHP) belt, northern …

Experimental multi-anvil study of the phase relations in subducted oceanic crust (mid-ocean
ridge basalt (MORB)) composition over a pressure range from 25 to 37 GPa, equivalent to …

As is typical of ultra-high pressure (UHP) terrains, the regional extent of the UHP terrain in
the Dabieshan of central China is highly speculative, since the volume of eclogites and …

A substantial amount of subducted basaltic crusts may exist in the lower mantle. It features
distinct chemical composition from the peridotitic mantle and plays important roles in the …
