Concealed deep beneath the oceans is a carbon conveyor belt, propelled by plate tectonics.
Our understanding of its modern functioning is underpinned by direct observations, but its …

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 …

Europa likely contains an iron‐rich metal core. For it to have formed, temperatures within
Europa reached 1250 K. Going up to that temperature, accreted chondritic minerals—for …

High-pressure dehydration of serpentinite during subduction generates fluids that flux and
melt the overlying mantle wedge, forming primary arc basalts. These basalts are …

Listvenites form by metasomatic transformation of variably serpentinized peridotites to
carbonate-quartz rocks due to extensive reaction with CO 2-bearing aqueous fluids. This …

Subducting oceanic plates carry large amounts of carbon into the Earth's interior. The
subducted carbon is mobilized by fluid and encounters ultramafic rocks in the mantle wedge …

Previous studies have concluded that dehydration of serpentinites in subduction zones
produces oxidizing fluids that are the cause of oxidized arc magmas. Here, observations of …

Subduction is a key element in the carbon cycle between the Earth's surface and deep
interior. In addition to pressure (P) and temperature (T), oxygen fugacity (ƒO 2) is an …

More than one teramole of carbon per year is subducted as carbonate or carbonaceous
material. However, the influence of carbonation/decarbonation reactions on seismic activity …

We investigate the late Cretaceous blueschist-facies (480° C-1.8 GPa) segment of the
Zagros suture zone, a well-preserved block-in-matrix paleo-subduction channel. We aim to …
