Flow laws and fabric transitions in wet quartzite
We investigated quartzite flow laws based on data from 21 different experimental studies on
samples deformed with added water at temperatures from 700 to 1200° C. Two clear trends …

Mechanical properties and recrystallization of quartz in presence of H2O: Combination of cracking, subgrain rotation and dissolution-precipitation processes
Natural quartzite samples, as-is and with 0.1 wt% of added H 2 O, have been deformed up
to∼ 30% bulk strain in axial shortening experiments with constant strain rate of∼ 10− 6 s− 1 …

What controlled the thickness of continental crust in the Archean?
VV Mai, J Korenaga - Geology, 2022 - pubs.geoscienceworld.org
Exposed continents are one of Earth's major characteristics. Recent studies on ancient
ocean volume and exposed landmasses suggest, however, that early Earth was possibly a …

Natural and experimental constraints on a flow law for dislocation‐dominated creep in wet quartz
We present a flow law for dislocation‐dominated creep in wet quartz derived from compiled
experimental and field‐based rheological data. By integrating the field‐based data …

Microphysical modeling of fault slip and stability transition in hydrothermal conditions
C Mei, JW Rudnicki - Geophysical Research Letters, 2023 - Wiley Online Library
Field and laboratory observations indicate that the frictional behaviors of faults depend on
hydrothermal conditions. We extend the microphysical Chen‐Niemeijer‐Spiers (CNS) model …
