Definition relative dating method
Stratigraphic dating remains very reliable when it comes to dating objects or events in undisturbed stratigraphic levels.
For example, the oldest human remains known to date in Canada, found at Gore Creek, have been dated using soil stratification.
There are two main categories of dating methods in archaeology: indirect or relative dating and absolute dating.
Relative dating includes methods that rely on the analysis of comparative data or the context (eg, geological, regional, cultural) in which the object one wishes to date is found.
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.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.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.
