Relative and absolute dating fossils

Comparison of commonly used dating techniques. Radiation, which is a byproduct of radioactive decay, causes electrons to dislodge from their normal position in atoms and become trapped in rocks in the crystal structure of the material. Dating methods like thermoluminescence , sedimentary stimulating luminescence and electron spin resonance , measure the accumulation of electrons in these imperfections, or "traps," in the crystal structure of the material. If the amount of radiation to which an object is determined remains constant, the amount of electrons trapped in the imperfections in the crystal structure of the material will be proportional to the age of the material. These techniques are relative to rocks that are up to about , years relative. However, once rocks or fossils become much older than that, all of the "methods" in the crystal structures become full and no relative electrons can accumulate, even if they are dislodged.
