Stratigraphic data is a required component in archaeological archives, but there is a growing problem for digital data archives, where stratigraphic data are often only held on paper or as scanned image copies (PDFs) of matrix diagrams. This means that they cannot be easily re-used in further analysis.
Marker horizons of tephra are used as a dating tool in archaeology, since the dates of eruptions are generally well-established. [3] One particular bolide impact 66 million years ago, which formed the Chicxulub crater, produced an iridium anomaly that occurs in a thin, global layer of clay marking the Cretaceous–Paleogene boundary.

A geoarchaeologist analyzes a stratigraphy on the route of the LGV Est high-speed railway line. geoarchaeologist at work on column sample Geoarchaeology is a multi-disciplinary approach which uses the techniques and subject matter of geography, geology, geophysics and other Earth sciences to examine topics which inform archaeological and chronological knowledge and thought.
Edward Cecil Harris, MBE, JP, FSA is a prominent Bermudian archaeologist.He is best known for the "Harris matrix", developed in February 1973 and considered by some to be the "industry standard" for stratigraphic archaeology.
In archaeology a section is a view in part of the archaeological sequence showing it in the vertical plane, as a cross section, and thereby illustrating its profile and stratigraphy. This may make it easier to view and interpret as it developed over time. Stylised section drawing
In single context excavation, a well-defined stratigraphic unit relating to a single depositional event, used as the primary unit for recording and analysis. culture An archaeological culture is a recurring assemblage of artifacts from a specific time and place that may constitute the material culture remains of a particular past human society.
Phasing a site represents reducing the site either in excavation or post-excavation to contemporaneous horizons whereas "digging in phase" is the process of stratigraphic removal of archaeological remains so as not to remove contexts that are earlier in time "lower in the sequence" before other contexts that have a latter physical stratigraphic ...
Animation showing interpretive grouping and phasing on matrix diagram. The Harris matrix is a tool used to depict the temporal succession of archaeological contexts and thus the sequence of depositions and surfaces on a 'dry land' archaeological site, otherwise called a 'stratigraphic sequence'.
