Historically, the greatest difficulty in geomorphology work has been the absolute dating of geomorphological surfaces, which reaches its maximum when the surface lacks any type of coating. It is then that the only criterion is either the creative imagination or the use of stable cosmogenic isotopes and, failing that, of radioactive ones, since as long as the stability of a surface can be guaranteed, the method will give an absolute age for the surface. Dating has different precision depending on which isotope is used. In the case of stable cosmogenics there is no age limitation, although in others (radioactive cosmogenics) it would be limited by the half-life of the isotope used. The detailed analysis of the geological and geomorphological history of the analyzed surface should never be neglected, more than in any other type of dating.
