The stratigraphic biography of an archaeological site. Timing depositional events

open access: yesArchaeometry, Volume 67, Issue S1, Page 49-73, June 2025.
Abstract The stratigraphic sequence of an archaeological site constitutes its biography, which details what was deposited, when it was deposited, and how the deposition occurred. However, many current methods of recording archaeological stratigraphy do not allow for a full reconstruction of a site's biography.
