How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

(50 days free access to full version here: https://authors.elsevier.com/a/1f9UbhdGqcjD9) Natural quartzite samples, as-is and with 0.1 wt% of added H2O, have been deformed up to ∼30% bulk strain in axial shortening experiments with constant strain rate of ∼10⁻⁶ s⁻¹ at 900 °C and 1 GPa, and in strain rate stepping ∼10⁻⁵ to ∼10⁻⁷ s⁻¹ at 900 °C and...
Quartz rheology in the presence of H2O is fundamental to model the deformation behavior of the continental crust. Microstructures in many naturally deformed quartzites in crustal conditions show evidence of crystal-plastic deformation, which is interpreted to be the consequence of the grain size insensitive (GSI) creep process. Experimental studies...
Quartzite samples of high purity with a grain size of ∼200 μm have been experimentally deformed by coaxial shortening in a solid medium apparatus at 900°C and at confining pressures ranging from 0.6 to 2 GPa. Most samples have been shortened by ∼30% with 0.1 wt.% added H2O. The samples deformed dominantly by crystal plasticity (dislocation creep),...
