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 …

Hydrous melting driven by changes in H2O storage capacity may occur in a variety of
settings in the mantle, including in oceanic basalt sources and in deeper regions above and …

This monograph deals with the part of the field of experimental rock deformation that is
dominated by the phenomena of brittle fracture on one scale or another. Thus a distinction …

The influence of water on the dynamics of the oceanic upper mantle is re-evaluated based
on recent experimental constraints on the solubility of water in mantle minerals and earlier …

Archean passive margins. In When Did Plate Tectonics Begin on Planet Earth?(eds KC
Condie & V. Pease.), pp. 149–56. Geological Society of America Special Paper no. 440 …

The current state and surface conditions of the Earth and its twin planet Venus are drastically
different. Whether these differences are directly inherited from the earliest stages of …

Migmatites are highly heterogeneous rocks found in high-grade metamorphic environments;
they are commonly encountered in the continental crust. Until now, many geologists have …

Abstract Intermediate-depth earthquakes (30–300 km) have been extensively documented
within subducting oceanic slabs, but their mechanics remains enigmatic. Here we decipher …

We review physical and chemical constraints on the mechanisms of melt extraction from the
mantle beneath mid–ocean ridges. Compositional constraints from MORB and abyssal …

We have performed an experimental study to quantify the high‐temperature creep behavior
of natural diabase rocks under dry deformation conditions. Samples of both Maryland …
