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".For a non-exhaustive list of relative dating methods and relative dating applications used in geology, paleontology or archaeology, see the following: Same as geologists or paleontologists, archaeologists are also brought to determine the age of ancient materials, but in their case the areas of their studies are restricted to the history of both ancient and recent humans.Thus, to be considered as archaeological, the remains, objects or artifacts to be dated must be related to human activity.Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.Older periods which predate the reliable fossil record are defined by absolute age.Each era on the scale is separated by a major and/or changing event.**If the images and/or text on any of the web pages do not appear evenly spaced and centered on your screen, which commonly occurs with AOL pages, maximize the individual page's window.

Many disciplines of archaeological science are concerned with dating evidence, but in practice several different dating techniques must be applied in some circumstances, thus dating evidence for much of an archaeological sequence recorded during excavation requires matching information from known absolute or some associated steps, with a careful study of stratigraphic relationships.

It was the case of an 18th-century sloop whose excavation was led in South Carolina (United States) in 1992.

Thus, from the oldest to the youngest, all archaeological sites are likely to be dated by an appropriate method.

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.
