TL;DR: In this article, a detailed study of high-pressure and ultra-high-pressure metamorphic suites incorporating knowledge of mineral chemistry and reactions, kinetics and disequilibrium, prograde and exhumation-related P-T paths, fluid flow and fluid-rock interactions, and experimental evidence for the physical and chemical properties of fluids at the pressures and temperatures experienced by subducting slabs.

TL;DR: In the Catalina Schist subduction-zone metamorphic complex (California), metasedimentary rocks show a decrease in N concentration and an increase in δ15Nair with increasing metamorphics grade.

TL;DR: In this paper, the authors evaluate the effects of varying prograde P-T paths on the magnitudes of devolatilization and chemical/isotopic alteration of subducting rocks.

TL;DR: In this article, the authors used the Li-Ca-Sr isotope system to quantitatively constrain the duration of subduction-zone fluid release at ∼ 70 km depth within subducting oceanic lithosphere, now exhumed in the Chinese Tianshan Mountains.

TL;DR: In this paper, the authors used stable isotope data from the Catalina Schist to predict mass changes along different P-T paths, and showed that both mechanisms could be effective at producing the range of observed features, even though the required equilibrium constants are only poorly estimated at the relevant P-Ts conditions.
