The emerging concept of a magma reservoir is one in which regions containing melt extend
from the source of magma generation to the surface. The reservoir may contain regions of …

In this manuscript we review experimental constraints for the viscosity of the upper mantle.
We first analyze experimental data to provide a critical review of flow law parameters for …

Melt extraction from the partially molten mantle is among the fundamental processes
shaping the solid Earth today and over geological time. A diversity of properties and …

Creep experiments on fine‐grained ice reveal the existence of three creep regimes:(1) a
dislocation creep regime,(2) a superplastic flow regime in which grain boundary sliding is an …

We review recent results concerning the rheology of the lithosphere with special attention to
the following topics: 1) the flexure of the oceanic lithosphere, 2) deformation of the …

The ability of a melt to separate from the residual crystals depends principally on the
viscosity of the melt. Low-viscosity magmas like carbonatites can separate from regions as …

The thermal structure of a generic subduction zone is investigated to elucidate the source
region of subduction zone volcanics. The steady state thermal field is evaluated for a model …

The general mathematical constraints for thermomechanical equilibrium of partial melts
under hydrostatic or nearly hydrostatic stress conditions are well known. However, melt …

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 …

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 …
