CHARACTERIZATION ORIGIN DATING Archaeology Cultural Heritage The average operated analytics THE METHODS OF DATING - Dendrochronology dating of wood Basing on the study of the elements of structure (skeletons, partitions, foundations), it requires to know the essence of the used wood and its region of origin. - Carbon 14 (radiocarbon - C14) dating of organic matters when associated with accelerator mass spectrometry (C14 AMS) This method allows in particular to dread the problems of migration of the small objects and to criticize the statistical distribution and the representativeness of dates.. - Thermoluminescence (TL) dating of warmed objects (ceramic, pebbles of quartz, flint...) To determine the age TL, it is necessarily necessary to measure the dose of natural irradiation, by experiments of thermoluminescence to the laboratory and the dose of annual irradiation, by measures of radioactivity in situ and radiochemical analyses.
