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 …

The concept of strength envelopes, developed in the 1970s, allowed quantitative predictions
of the strength of the lithosphere based on experimentally determined constitutive equations …

This book is a systematic guide to the recognition and interpretation of deformation
microstructures and mechanisms in minerals and rocks at the scale of a thin section …

Eclogite, the high-pressure equivalent of basalt, is common in ultrahigh-pressure
metamorphic terranes and constitutes the oceanic crust after it is subducted into the mantle …

We investigated the high‐temperature creep strength of fine‐grained anorthite‐diopside
rocks at temperatures ranging from 1323 K to 1523 K and at 300 MPa confining pressure in …

Clinopyroxene (omphacite) microfabric studies in eclogites are useful in characterizing the
deformation that has affected deeper parts of subduction zones. We present the microfabrics …

We have determined diffusional and dislocation creep rheologies for clinopyroxenite Ca1.
0Mg0. 8Fe0. 2Si2O6 under dry conditions by deforming natural and hot‐pressed samples at …

We use an anisotropic viscoplastic self-consistent (VPSC) model to simulate the
development of omphacite lattice preferred orientations (LPOs) in response to deformation …

We have investigated the rheology of hot-pressed polycrystalline omphacite (Di58Jd42,
space group C2/c) at strain rates of 10− 4–10− 5/s, temperatures of 1300–1500K and a …

Eclogite plays an important role in mantle convection and geodynamics in subduction
zones. An improved understanding of processes in the deeper levels of subduction zones …
