The basis of ESR dating is the ratio of total nuclear radiation amount absorbed by quartz to per year radiation amount that was calculated according to K

Th and U contents in surrounding substances.The ESR age of different genetic quartz may have different geological significance

so it is necessary to pay attention to the occurrence and genesis of the quartz during sampling.In practical

the ESR age of quartz is mainly used to distinguish different fissure and solution stages and ages;to distinguish tectonic periods and ages.Combined with the configuration and colour of the quartz crystal

the inclusions and the associated minerals

ESR dating could also be used to distinguish the geological features during hydrocarbon migration

to study the development and evolution rule of the fissur and solution.
