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

The minerals constituting the Earth's upper mantle are nominally anhydrous silicates
(NAMs). However they do contain hydrogen as a trace element, decorating point defects in …

Chemically zoned garnet growth and coeval modification of this zoning through diffusion are
calculated during prograde metamorphic heating to temperatures of up to 850° C. This …

At subduction zones, oceanic lithosphere that has interacted with sea water is returned to
the mantle, heats up during descent and releases fluids by devolatilization of hydrous …

The advent of polarized light microscopy in the middle of the 19th century allowed
mineralogists and petrologists interested in igneous rocks to recognize the widespread …

Natural processes driven by heat flow can be understood using quantitative reconstruction
of the thermal history of accessory and common minerals that were formed or modified in …

Diffusion is due to thermally activated atomic-scale random motion of particles (atoms, ions
and molecules) in minerals, glasses, melts, fluids, and gases (Fig. 1). The random motion …

High precision and accuracy with in situ analysis has been a “holy grail” for generations of
stable isotope geochemists who employed a range of strategies for separation of …

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 …

Dolomite precipitation models and kinetics are debated and complicated due to the complex
and temporally fluctuating fluid chemistry and different diagenetic environments. Using well …
