Description

We have advanced the conventional MA6-6 type AE measurement system to establish a large strain shear deformation field under pressure conditions up to 10 GPa, enabling in-situ X-ray observation of reaction-induced shear instability. This achievement allows us for the monitoring of slip displacement resulting from strain localization and the evaluation of slip stability through AE activity at shear strains exceeding 200%, in addition to the acquisition of stress-strain curves and reaction kinetics. We applied this methodology to the dehydration reactions of antigorite and lawsonite, as well as olivine-spinel phase transition in fayalite. The method developed herein provides a powerful tool for experimental research on shear instability processes, contributing to a better understanding of the mechanisms underlying intermediate-depth earthquakes.
