Pollen dating method

The extent of documentation varied considerably in 'historical' cultures and the information that survives is determined by a variety of factors.If a context containing burnt debris and broken artefacts is excavated on a site from a historical period, it is tempting to search the local historical framework for references to warfare or a disaster in the region, and to date the excavated context accordingly.

Relative dating methods are used to determine only if one sample is older or younger than another.

These techniques both place assemblages of artefacts into relative order.

Petrie used sequence dating to work back from the earliest historical phases of Egypt into pre-dynastic Neolithic times, using groups of contemporary artefacts deposited together at a single time in graves.

Pollen analysts (or palynologists) extract pollen from soil that has been excavated or removed from the ground in auger-cores. Radiocarbon dating is commonly used to date these layers so that the changing pollen presence over time can be measured.

The soil is mixed with water and placed in a centrifuge (a machine that spins it very fast).
