Strain in the lithosphere localizes into tabular zones known as shear zones that grow from
small outcrop-size individual zones to large composite structures. Nucleation is related to …

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 …

Abstract The India‐Eurasia collision zone is the largest deforming region on the planet;
direct measurements of present‐day deformation from Global Positioning System (GPS) …

Microtectonics deals with the interpretation of microstructures, small-scale deformation
structures in rocks that yield abundant information on the history and type of deformation and …

55 4.4 Experimental techniques 57 4.5 Some general trends in elasticity: Birch's law 59 4.6 …

Quartz veins in the Eastern Tonale mylonite zone (Italian Alps) were deformed in strike-slip
shear. Due to the synkinematic emplacement of the Adamello Pluton, a temperature gradient …

We use the remarkable similarity between microstructures preserved in naturally and
experimentally deformed quartzites as a basis to evaluate quartzite flow laws and their …

In order to determine a recrystallized grain size piezometer for quartz, we deformed Black
Hills quartzite in a molten salt assembly in a Griggs apparatus at 1.5 GPa, 800 to 1100° C …

In the last decade, significant progress has been made toward understanding how plate
tectonics is generated from mantle dynamics. A primary goal of plate-generation studies has …

Microstructural analyses of peridotite mylonites from the oceanic lithosphere indicate that
shear localization results from the combined effects of grain size reduction, grain boundary …
