Direct dating in archaeology
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.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 approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.Certain features or artifacts may be normally associated with particular contexts, for example a pottery type may be found in the context of certain burials.If such an artifact is found out of context, it may suggest the previous presence of a burial, the robbery of a burial, or a place of manufacture of the pots that accompanied burials.Direct dating is when you date an object by taking a sample of itself and doing carbon dating on it for example.Indirect dating is something like stratigraphic dating where you date the strata above and below the object or artifact and get a timeframe that you can place the object in.
Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.
Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things.
Stratigraphy is based on the law of superposition--like a layer cake, the lowest layers must have been formed first.
That means that the play was without fail written after (in Latin, post) 1587.
The same inductive mechanism is applied in archaeology, geology and paleontology, by many ways.
