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 …

At the core of petrochronology is the relationship between geochronology and the
petrological evolution of major mineral assemblages. The focus of this chapter is on …

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 …

A better understanding of the subduction zone fluid cycle and its chemical–mechanical
feedback requires in-depth knowledge about how fluids flow within and out of descending …

Fluid–rock interactions are a fundamental component of geodynamic processes. They link
mass and energy transfer with large-scale tectonic deformation and drive mineral deposit …

The fate of subducted CO2 remains the subject of widespread disagreement, with different
models predicting either wholesale (up to 99%) decarbonation of the subducting slab or …

The oceanic crust that enters a subduction zone is generally recycled to great depth. In rare
and punctuated episodes, however, blueschists and eclogites derived from subducted …

Partial melting is the fundamental process by which juvenile crust was produced from the
mantle and subsequently reworked to become the stable, compositionally-differentiated …

The thermal structure of subduction zones is fundamental to our understanding of the
physical and chemical processes that occur at active convergent plate margins. These …

High‐pressure rocks from the island of Ios in the Greek Cyclades were examined to resolve
the P–T conditions reached during subduction of the two distinct lithotectonic units that are …
