Optically stimulated luminescence dating method

26 Jul

An outline of the general physical principles of luminescence dating is given.

A case study of fluvial sands from the lower terrace of the Moselle valley is then presented to describe the range of field and laboratory procedures required for successful luminescence dating.

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.

These investigations show that the materials possess good OSL properties and the sensitivity is comparable to that of the commercial α-Al: C.Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history, archaeology, geology, paleontology, astronomy and even forensic science, since in the latter it is sometimes necessary to investigate the moment in the past in which the death of a cadaver occurred.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.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".
