Two broad categories of classification methods are relative dating and absolute dating.Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.Age of deposition should not be confused with the date of material enclosed in deposit.Cross dating involves comparing similar artifacts from similar sites that may be of similar age.These artifacts can be placed in order, but requires external information to determine which end of the series is younger or older.Absolute dating determines the age of artifacts in terms of the number of years before the present, with reference to a fixed time scale.

Relative ages: Relative ages are based mainly on observed or inferred field relationships and stratigraphy/biostratigraphy, rather than laboratory measurements.if you had a volcanic ash in one place and wanted to know if it was the same as the volcanic ash in another place, you could date both absolutely to test the correlation, or for example you could see if the ash was in the same stratigraphic/biostratigraphic position at both locations.
