Chemical dating techniques

Using relative dating the fossil is compared to something for which an age is already known.For example if you have a fossil trilobite and it was found in the Wheeler Formation.In such cases subjective element cannot be ruled out.But, for a single culture site the method is quite reliable.Archaeology dating techniques can assure buyers that their item is not a fake by providing scientific reassurance of the artefact's likely age.Archaeological scientists have two primary ways of telling the age of artefacts and the sites from which they came: relative dating and absolute dating.

Limits to relative dating are that it cannot provide an accurate year or a specific date of use.

Recent experiments on mica and natural glasses have shown that the number of irradiation damage tracks created by spontaneous fission of uranium atoms in these materials is a useful measure of geological time.

In order to be able to extend this technique to other minerals it is necessary to be able to observe and identify fission tracks.

The deposit thus occurring forms layers depending on the nature of the material brought in by the people inhabiting the area.

According to this method, the upper deposits are younger and the lower deposits are older.
