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. So since the death of the organism. 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. First we try to cut a piece of the tooth, and then we extract the different dental tissues.

The earthquake is a phenomenon that the fault surface is cracked by the surrounding force to pull or push and then, the base rock moves rapidly on the boundary of fault plane. This base rocks shift is called the geological fault. The active fault is the geological fault that has the possibility to move repeatedly in recent geological age and in the future. The fault is classified to the normal fault, the reverse fault, the strike-slip fault and the left-lateral fault by the difference in the movement displacement.

Geological fault and ESR -Approach using ESR dating method-
Even with such weak natural radiation, radiation damage in materials generates unpaired electrons. This damage is generated even with artificial radiation. If natural radiation continues to irradiate at a constant intensity and if unpaired electrons are generated in proportion to the radiation dosage, the quantity of unpaired electrons in a material should increase in proportion to the elapsed time, and a dating method therefore becomes possible. Other dating methods, also measuring radiation damage, e.
