Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object.

It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years.

Cultural seriations are based on typologies, in which artifacts that are numerous across a wide variety of sites and over time, like pottery or stone tools.

By measuring the amount of radioactive decay of a radioactive isotope with a known half-life, geologists can establish the absolute age of the parent material.In archaeology, seriation is a relative dating method in which assemblages or artifacts from numerous sites, in the same culture, are placed in chronological order.Where absolute dating methods, such as carbon dating, cannot be applied, archaeologists have to use relative dating methods to date archaeological finds and features.A number of radioactive isotopes are used for this purpose, and depending on the rate of decay, are used for dating different geological periods.More slowly decaying isotopes are useful for longer periods of time, but less accurate in absolute years.Seriation is a standard method of dating in archaeology.
