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 …

The first samples collected by the Mars 2020 mission represent units exposed on the Jezero
Crater floor, from the potentially oldest Séítah formation outcrops to the potentially youngest …

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 …

The lithium isotope system is increasingly being applied to a variety of Earth science studies,
as the burgeoning literature attests; over 180 papers have been published in the last twelve …

Sulfur belongs among H2O, CO2, and Cl as one of the key volatiles in Earth's chemical
cycles. High oxygen fugacity, sulfur concentration, and δ34S values in volcanic arc rocks …

Metamorphic devolatilization of subducted slabs generates aqueous fluids that ascend into
the mantle wedge, driving the partial melting that produces arc magmas. These magmas …

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

Garnet could be the ultimate petrochronometer. Not only can you date it directly (with an
accuracy and precision that may surprise some), but it is also a common rock-forming and …

Water within the oceanic lithosphere is returned to Earth's surface at subduction zones.
Observations of metamorphosed veins preserved in exhumed slabs suggest that fluid can …
