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 …

This chapter presents an overview of diffusion data for pyroxenes, amphiboles and micas.
These minerals are grouped together since amphiboles and micas are closely related in …

Deformation experiments have been conducted to investigate the effect of melt fraction and
grain size on the creep behavior of olivine aggregates in the diffusion creep regime. Both …

Mounting evidence suggests that partial disequilibrium—meaning disequilibrium for some
elements, but not for others—may be a common but rarely detected phenomenon during …

Abstract Garnets from the Zermatt-Saas Fee eclogites contain narrow central peaks for Lu+
Yb+ Tm±Er and at least one additional small peak towards the rim. The REE Sm+ Eu+ Gd+ …

1.1. Strategy and Techniques For a rock of given mineralogy and microstructure, the
variables important in determining strength are pressure, temperature, strain, strain history …

Stable isotopes are a powerful tool for deciphering the fluid histories of metamorphic
terranes. The nature of fluid flow, fluid sources, and fluid fluxes can be delineated in well …

Diffusion is an integral part of many geologic processes and an increasing portion of the
geologic literature is devoted to the measurement, estimation, and application of diffusion …

Recent years have seen a rapid expansion in the acquisition and use of information on
diffusive transport in phases relevant to the solid Earth (crystals, melts and fluids). Although …

Accurate values of diffusion coefficients for aqueous species are a requisite for predicting
mass transfer in many geochemical processes. Tracer diffusion coefficients can be …
