Absolute dating methods mainly include radiocarbon dating, dendrochronology and thermoluminescence.
Stratigraphy Inspired by geology, stratigraphy uses the principle of the superposition of strata which suggests that, in a succession of undisturbed SOILS, the upper horizons are newer than the lower ones.
Thu, Dec 15, 2016 New research conducted by scientists at the University of York reveals for the first time that Europe's earliest humans did not use fire for cooking, but had a balanced diet of meat and plants -- all eaten raw.
For those researchers working in the field of human history, the chronology of events remains a major element of reflection.
Thu, Nov 09, 2017 New research shows that early farmers who migrated to Europe from the Near East spread quickly across the continent, where they lived side-by-side with existing local hunter-gatherers while slowly mixing with those groups over time.
Indeed, carbon 14 (14C) is formed from the reaction caused by cosmic rays that convert nitrogen into carbon 14 and then carbon dioxide by combining with carbon 12 (12C) and carbon 13 (13C ), which are stable carbon isotopes.
This technique is frequently used when it is impossible to make use of absolute dating methods; it generally allows archaeologists to identify the period to which a cultural site or object belongs, without specifying the date of occupation.
This method is primarily applied to projectile points and ceramic vessels.
Generally, each stratum is isolated in a separate chronological unit that incorporates artifacts.
However, this method is sometimes limited because the reoccupation of an area may require excavation to establish the foundation of a building, for instance, that goes through older layers.
