) Archeologists may encounter stratigraphy that has been disrupted.Distortions can occur during or after material deposition that may cause strata to disappear in one area of the site and reappear farther along at a different distance from the surface. Landfills, dumps, and landslides or other earth movements may distort a site's stratigraphy.This section explores dating techniques that archeologists use to establish relative time and absolute time to date sites and the corresponding artifacts and events.In some cases archeologists date the objects themselves; in others they date the context from which artifacts were recovered.Artifacts deposited in one stratum-a more or less homogeneous material, visually separable from other levels by a distinct change in color, texture, or other characteristic-have a distinct relationship with artifacts recovered from strata (plural of stratum) above or below them.These kinds of time relationships between stratified layers are what archeologists call relative time or relative chronology.
Some of them are the result of human activity, like house building.
(4/30/01) for instance, earlier, later, more recent, and so forth.
Each object at an archeological site has a different time relationship with every other object at that site.
All workers must be aware of them and of their importance to the final interpretations of the excavation.
In one sense, though, disturbances are what excavation is about.
