The stratigraphy of an archaeological site can be used to date, or refine the date, of particular activities ("contexts") on that site.
For example, if a context is sealed between two other contexts of known date, it can be inferred that the middle context must date to between those dates.
Dating material drawn from the archaeological record can be made by a direct study of an artifact, or may be deduced by association with materials found in the context the item is drawn from or inferred by its point of discovery in the sequence relative to datable contexts.Dating is carried out mainly post excavation, but to support good practice, some preliminary dating work called "spot dating" is usually run in tandem with excavation.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."Right now, we're still trying to figure out a lot of stuff because we're on different coasts and our son is getting older," he explained.
He has been in two celebrity relationships averaging approximately 10.5 years each. Sam Bennett on Private Practice "That was a falling-down point for me with women in the past.
Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology.
This usually requires what is commonly known as a "dating method".
In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the oldest and the most recent possible moments when an event occurred or an artifact was left in a stratum.
But this method is also useful in many other disciplines.
For example, in a stratum presenting difficulties or ambiguities to absolute dating, paleopalynology can be used as a relative referent by means of the study of the pollens found in the stratum.
