CATEGORY: site DEFINITION: A cave site at Finale Ligure on the Italian Riviera whose excavation revealed a stratigraphy extending from the Upper Palaeolithic through Epi-Palaeolithic, to Early, Middle, and Late Neolithic, as well as poor levels from the Bronze and Iron Ages up to the CATEGORY: geology DEFINITION: Volcanic material of less than 4 mm in diameter that falls quickly and can bury sites, preserving the stratigraphy, people, and artifacts.Ash is also the soft, solid remains of burned organic material as from cremation.
It is not the same as the sequencing of soil horizons in a soil profile CATEGORY: technique DEFINITION: The study and interpretation of the stratification of rocks, sediments, soils, or cultural debris, based on the principle that the lowest layer is the oldest and the uppermost in the youngest -- a major tool in establishing a sequence.
The later ones will be progressively further out as the cemetery expands.
The concept can be a helpful tool in the interpretation of a site. It is the establishment of a chronology in which occurrences can be placed in the correct sequence relative to each other or to some known succession of events.
Stratigraphy is by definition obtained from superposed deposits, but other circumstances can be treated in the same way.
For example, the oldest burials are likely to be those nearest the settlement, the top of a hill, or some other favored position.
