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 …

Short-and long-term processes at or close to the subduction plate interface (eg, mineral
transformations, fluid release, seismicity and more generally deformation) might be more …

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

The sources of fluids and metals in porphyry systems of continental-collision settings are
poorly constrained. Mercury isotopes display unique mass-independent fractionation …

Oceanic lithosphere is generated at divergent plate boundaries and disappears at
convergent plate boundaries. Seafloor spreading and plate subduction together constitute …

The transport of water from subducting crust into the mantle is mainly dictated by the stability
of hydrous minerals in subduction zones. The thermal structure of subduction zones is a key …

The geochemical signatures of subducting crust have been identified in various types of
mafic igneous rocks at convergent plate boundaries, where island arc basalts (IAB) and …

We extracted all volcanic arc rock analyses calculated to be in equilibrium with mantle
olivine from the global georoc database. This results in 938 primitive melt compositions from …

In subduction zones, sediments and hydrothermally altered oceanic crust, which together
form part of the subducting slab, contribute to the chemical composition of lavas erupted at …

The interface between subducting oceanic slabs and the hanging wall is a structurally and
lithologically complex region. Chemically disparate lithologies (sedimentary, mafic and …
