The Yangsan Fault, a long-lived intracontinental fault in SE Korea, exhibits various slip behaviors, including coseismic slip and aseismic creep. However, there is insufficient knowledge of deformation microstructures to reveal the deformation mechanisms operating within the fault. In this study, we present an analysis of the mechanical behaviors d...

Background The intricate textural patterns commonly observed in metamorphosed and recrystallized zircon (ZrSiO 4 ) underscore the crucial necessity of understanding the underlying mechanisms governing their formation to ensure accurate interpretation of the chemical and isotope data they contain. This study employed a combination of microanalytical...

Lawsonite is an important mineral for understanding seismic anisotropy in subducting oceanic crust due to its large elastic anisotropy and prevalence in cold subduction zones. However, there is insufficient knowledge of how lawsonite twinning affects seismic anisotropy, despite previous studies demonstrating the presence of twins in lawsonite. This...

The eclogite in the Flem Gabbro from Flemsøya Island of the Western Gneiss Region in Norway contains atypical eclogitic minerals, such as olivine and orthopyroxene, and can be texturally divided into weakly deformed massive eclogite (MEC) and strongly deformed foliated eclogite (FEC). Based on phase equilibria modeling, peak metamorphic pressure‐te...
