Nanoparticles in the ductile shear zones of faults are thought to be closely related to fault activity and the seismogenic mechanism. Using scanning electron microscopy (SEM), nanoparticles with a variety of morphological characteristics were found in mylonite, gneiss, and schist from
the ductile shear zones of the Red River Fault. The nanoparticle morphology is dominated by rods, spherulites, massive forms, lamellae and film-like shapes. Energy spectrum analysis showed that the nanoparticles were mainly composed of silicate minerals, while a few contained carbonate minerals.
Nanoparticles follow certain spatial distribution rules in ductile shear zones. Near the main fault plane of the Red River Fault Zone, the nanoparticles are dispersed, brittle and spherulitic, with a small particle diameter. Those far from the main fault plane are agglomerated and plastic,
with rod-like, massive, lamellar and film-like shapes, and a relatively large particle diameter. According to nanoparticle development characteristics and the theory of microscopic deformation, a study on the formation mechanism of nanoparticles in the ductile shear zones of the Red River
Fault was carried out. The rock minerals are the first to experience granulation, through intergranular movement under strong strain, generating brittle spherulitic particles, which eventually loosen and disperse. In the later stages, through recrystallization, nanoparticle crystals may become
large or develop various morphologies.
