3 methods of dating artefacts

In the core regions surface sites have been registered almost exclusively.For dating such site assemblages, we depend on typochronological dating.For each phase the chronologically most characteristic (guide) artefacts have been selected.

Before this, archaeologists and scientists relied on deductive dating methods, such as comparing rock strata formations in different regions.These diagrams are based both on excavated and surface finds and provide an excellent illustration of the problems outlined above.First of all there are relatively large differences between the several schemes regarding the various cultural phases, the artefact typology and the cultural attribution of the artefact types.Archaeologists and scientists use absolute dating methods on samples ranging from prehistoric fossils to artifacts from relatively recent history.Chronometric techniques include radiometric dating and radio-carbon dating, which both determine the age of materials through the decay of their radioactive elements; dendrochronology, which dates events and environmental conditions by studying tree growth rings; fluorine testing, which dates bones by calculating their fluorine content; pollen analysis, which identifies the number and type of pollen in a sample to place it in the correct historical period; and thermoluminescence, which dates ceramic materials by measuring their stored energy.

All other artefact types are too indistinct typologically and/or not specific enough chronologically to be used as a means of dating.
