Permeability of the continental crust: Implications of geothermal data and metamorphic systems
In the upper crust, where hydraulic gradients are typically 10 MPa km−1, the mean permeabilities required to accommodate the estimated metamorphic fluid fluxes decrease from ∼10−16 m² to ∼10−18 m²Expand

Low heat flow inferred from >4 Gyr zircons suggests Hadean plate boundary interactions
The first ∼600 million years of Earth history (the ‘Hadean’ eon) remain poorly understood, largely because there is no rock record dating from that era. Detrital Hadean igneous zircons from the JackExpand

The chemistry of subduction-zone fluids
Abstract Subduction zones generate voluminous magma and mediate global element cycling. Fluids are essential to this activity, yet their behavior is perhaps the most poorly understood aspect of theExpand

Reevaluating carbon fluxes in subduction zones, what goes down, mostly comes up
Significance This paper reviews carbon fluxes into and out of subduction zones, using compiled data, calculations of carbon solubility in aqueous fluids, and estimates of carbon flux inExpand

Geochronologic and thermobarometric constraints on the evolution of the Main Central Thrust, central Nepal Himalaya
The Main Central Thrust (MCT) juxtaposes the high-grade Greater Himalayan Crystallines over the lower-grade Lesser Himalaya Formation; an apparent inverted metamorphic sequence characterizes theExpand

The solubility of quartz in H2O in the lower crust and upper mantle
The solubility of quartz in H2O has been determined experimentally from 5 to 20 kb and 500 to 900°C. The results double the pressure range over which the molality of aqueous silica (mSiO2(aq)) hasExpand

Tectonic evolution of the northeastern Pamir: Constraints from the northern portion of the Cenozoic Kongur Shan extensional system, western China
The late Cenozoic Kongur Shan extensional system lies along the northeastern margin of the Pamir at the western end of the Himalayan-Tibetan orogen, accommodating east-west extension in the Pamir. AtExpand

Early Paleozoic Tectonic and Thermomechanical Evolution of Ultrahigh-Pressure (UHP) Metamorphic Rocks in the Northern Tibetan Plateau, Northwest China
Coesite- and diamond-bearing ultrahigh-pressure (UHP) metamorphic rocks represent continental materials that were once subducted to depths of >90 km. Identifying how these rocks were subsequentlyExpand

Equilibrium high-temperature Fe isotope fractionation between fayalite and magnetite: An experimental calibration
Abstract The iron isotopic fractionation factor between magnetite and fayalite was measured at high temperature in a piston–cylinder apparatus. For the first time, the three-isotope methodExpand
