Methods of chronometric dating

On the other hand, absolute dating includes all methods that provide figures about the real estimated age of archaeological objects or occupations.These methods usually analyze physicochemical transformation phenomena whose rate are known or can be estimated relatively well.Archeologists use numerous systems to assign dates to objects, places, and events. Geomorphology: The scientific study of landforms and the processes that create them.

Generally, each stratum is isolated in a separate chronological unit that incorporates artifacts.Excavation: Archeologists excavate buried cultural remains to both gather information about past human behavior and to preserve and protect cultural resources from destruction, either from human or natural processes. Discussed below are the three major types of dating used in archeology – relative dating, chronometric dating, and absolute dating – and some of the more popular methods employed in each general category.Archeological excavations, or “digs,” are conducted using very specific methods and rigorous vertical and horizontal spatial controls. Relative dating in archeology determines the age of cultural material in relation to other cultural material, but does not produce precise dates.Some important aspects of archeological excavations include the removal of overburden, or the soils overlying the cultural materials, either by hand or machine; photographic and cartographic documentation of artifacts, structural components, features, soil types and changes, and other indications of human presence within a site; careful screening or sieving of soils to ensure all important artifacts and ecofacts are collected from the site; and careful documentation of field procedures, personnel, and equipment. For examples, one ceramic type may be determined older than another may, allowing the types to be placed in a temporal sequence relative to each other.Typically, excavation takes three forms: monitoring, testing, and data recovery. Archeologists practice many types of relative dating, some of the more common of which are discussed below: Chronometric dating techniques provide a range of dates that are relative, not absolute.
