The article is in straightforward language and the non-technical reader could profitably work through it.

Archaeology dating techniques can assure buyers that their item is not a fake by providing scientific reassurance of the artefact's likely age.

Absolute dating relies on biological, chemical (radiometric), geological/electromagnetic, or historical investigation to obtain the date range of a deposit.
