Document Summary
Lecture 12 part 2 formation of the archaeological record. Natural formation processes: affect the record after humans are done with it, three main sets of natural processes. Geologic processes that effect what you recover in sites. E. g. erosion, cryoturbation (freezing and thawing, major problem in the arctic), glaciation, eolian (wind-blowing processes; causes deflated sites), earthquakes, volcanic eruptions (e. g. pompeii) E. g. rodents, earthworms, scavengers, trees (fallen trees, roots, etc. ) The older the site, the more its subject to biological processes. E. g. acidic soils (destroys organic artifacts), corrosion of metals, oxidization, etc.
