  • Esr dating rangeNavy dating services Electron Spin Resonance Dating, or ESR dating, is a technique used to date newly formed materials, which Radiocarbon dating cannot, like carbonates , tooth enamel , or materials that have been previously heated like igneous rock. Electron spin resonance dating was first introduced to the science community in , when Motoji Ikeya dated a speleothem in Akiyoshi Cave, Japan. The age of substance can be determined by measuring the dosage of radiation since the time of its formation.

    And an age is actually the result of a long and complex analytical procedure. So we are going to show you here how we date a sample with the ESR method. The goal of this procedure is to try to estimate the radiation dose absorbed by the enamel layer during the geological time. A few keys here to understand what I'm going to mention later on, is that ESR stands for Electron Spin Resonance, which is a spectroscopic analytical technique that looks at paramagnetic properties of materials.
