The importance of stratigraphy is good and well but it still does not provide an accurate form of dating, it all involves speculation.

This is since as a downfall since archaeological research strives in the most accurate form of understanding of the past societies and cultures.

The goal of archaeologist is ultimately to know how old sequences, sites and artefacts are in calendar years.

To accomplish this absolute dating methods are used.

In archaeology dating can be categorised into relative dating and absolute dating techniques.

In moving forward explain the importance of radio carbon dating, potassium argon dating, seriation and stratigraphy to the archaeological study, one must first understand the difference between relative dating and absolute dating in archaeology.

This essay shall focus on the importance of radio carbon dating, potassium argon dating, seriation and stratigraphy to the archaeological study.

Accurate dating has always been of importance to scientist and archaeologist alike.

According to Renfrew and Bahn, “stratigraphy is the study of stratification- the laying down or depositing of strata one above the other.” (Renfrew and Bahn 2008, 122).

This basically involves ordering things into sequences.

A succession of layers should provide a relative chronological sequence from the earliest (the bottom layer) to the latest (top), as seen in figure one.

Contextual seriation, also called sequenced dating is where artefacts are arranged according to the frequencies of their co- occurrence in specific context.

In the nineteenth century Sir Flinders Petrie was the founding father of this type of seriation. Brainerd in their paper published in American Antiquity in 1951 hypostasised two statements about frequency seriation.

It’s important to note that stratigraphy involves the Law of Superposition.
