Quick Summary

Piezoremanent magnetization (PRM) is a type of remanent magnetization that occurs when a material undergoes mechanical deformation while in a magnetic field. This deformation can be caused by hydrostatic pressure, shock impact, or directed tectonic stress. The most significant effects of PRM are observed during plastic deformation, which irreversibly alters the structure of magnetic minerals. This phenomenon is distinct from other types of remanent magnetization, such as thermoremanent magnetism (acquired during cooling) or chemical remanent magnetization (acquired during chemical changes).12

Types of remanent magnetization
PRM (pressure remanent, or piezoremanent, magnetization) arises when a material undergoes mechanical deformation while in a magnetic field. The process of deformation may result from hydrostatic pressure, shock impact (as produced by a meteorite striking the Earth’s surface), or directed tectonic stress. There are magnetization changes with stress in…
