For those researchers working in the field of human history, the chronology of events remains a major element of reflection.

Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.

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.

Typology Typology is a method that compares reference objects in order to classify them according to their similarity or dissimilarity and link them to a specific context or period.

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.

Absolute dating methods mainly include radiocarbon dating, dendrochronology and thermoluminescence.

Dendrochronology Dendrochronology is a method that studies the rings of tree trunks to define characteristic sequences by analyzing the morphology of growth rings for a given species.

This method is based on the principle that the variation in tree growth from one year to another is influenced by the degree of precipitation, sunshine, temperature, soil type and all ambient conditions and that, consequently, reference patterns can be distinguished.

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).
