Research article 24 Jan Correspondence : Georgina E. King georgina. The electron spin resonance ESR of quartz has previously been shown to have potential for determining rock cooling histories; however, this technique remains underdeveloped.
The US model defined by these authors is based on the following equation:. Examples of dating esr may be found in Reference 9. Fossil teeth are usually collected either on site or chosen from collections. Large mammal teeth, and especially from herbivores, are usually preferred, since they offer a thicker esr layer. Then, in dating measurements of the natural radioactivity at the exact place where the sample esr collected during excavations, or at least the closest possible, is carried out to evaluate the gamma dose rate.
Occasionally, it also carries out work in dosimetry and characterization of modern or old geo-materials. Although ESR spectroscopy gives the name to the dating method, it is only used to calculate the equivalent dose DE , one of the two parameters necessary to calculate the final date. The ESR-based dosimetric reconstruction process is key to obtaining the second parameter: the dose rate D.
