Definition of cultural dating

An initial reading dates the specimen which is then calibrated by considering this date and its correspondence with the measurable level of carbon 14 stored over time in the growth rings of certain tree species, including redwood and pine bristol.

The results of radiocarbon dating are expressed in years and include a time range (eg, 630± 60 BP).

Subsequently, the calibration of that date provides a time interval where the event or object being dated can be situated (eg, 1275-1425 AD).

Radiocarbon dating, however, can only be used for dating objects that are less than 50 000 years.

Several sets of rings from different trees are matched to build an average sequence.

Subsequently, overlapping series of average sequences from trees that died at different times and come from various sources (ie, the wood of historic buildings, archaeological and fossil woods) are used to build a chronological sequence covering several hundred years which becomes a reference.

The bones were buried under (and are therefore older) a layer of ash that resulted from a volcanic eruption dating back to 7000 years BP (Before Present; "present" indicates c. Subsequently, radiocarbon dating, an absolute dating technique, was used to date the bones directly and provided a date of 8250 BP, showing how useful the combined used of relative and absolute dating can be.

Moreover, stratigraphic dating is sometimes based on the objects that are found within the soil strata.This is the only type of techniques that can help clarifying the actual age of an object.Absolute dating methods mainly include radiocarbon dating, dendrochronology and thermoluminescence.Radiocarbon Dating Radiocarbon dating is the most widely used dating technique in archaeology.It relies on a natural phenomenon that is the foundation of life on earth.Stratigraphic dating remains very reliable when it comes to dating objects or events in undisturbed stratigraphic levels.
