Electron spin resonance dating is based on the principle that natural radiation creates paramagnetic defects in minerals. The method has been applied to various minerals starting from calcite of speleothems. As quartz is one of the most common minerals on the surface of the Earth, many applications are available on various geological events occurring on the Earth. The present review article summarizes the recent research results and directions of electron spin resonance dating of quartz.

Key words: electron spin resonance (ESR) dating; quartz; paramagnetic defect; Quaternary; tephra; sediment
