Initially, it may seem extremely daunting to be sitting in front of several thousand carats of
small diamonds, knowing that the likelihood of finding a diamond with a meaningful …

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 …

We demonstrate that the deep volatile storage capacity of magma oceans has significant
implications for the bulk composition, interior, and climate state inferred from exoplanet mass …

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 …

Most diamonds are metasomatic minerals, which means they grew from fluids or melts that
moved through solid mantle rocks and chemically interacted with them. The involvement of …

Subducted crust refertilizes the subarc mantle wedge as well as the deep convecting mantle.
In the subarc region, mass transfer occurs mainly through fluids, melts, or supercritical …

Three distinct groups of eclogites (low-Mg–Ti eclogites, high-Ti eclogites and Mg-rich
eclogites) and ultramafic rocks from the depth interval of 100–680 m of the Chinese …

Hydrous melting driven by changes in H2O storage capacity may occur in a variety of
settings in the mantle, including in oceanic basalt sources and in deeper regions above and …

The origin of cratonic diamonds is reviewed on the basis of nearly 5000 analyses of silicate,
oxide and sulphide inclusions in diamonds. Compositional fields are defined for common …

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 …
