In a landmark study, archaeologist James Ford used seriation to determine the chronological order of American Indian pottery styles in the Mississippi Valley.
This also works with stone tools which are found abundantly at different sites and across long periods of time.
Principle of stratigraphy[ edit ] Stratigraphic dating is based on the principle of depositional superposition of layers of sediments called strata. This principle presumes that the oldest layer of a stratigraphic sequence will be on the bottom uxed the most recent, or youngest, will be on Radiocarbon hookup could be used to date top. The earliest-known hominids in East Africa are often found in very specific stratigraphic contexts that have implications for their relative dating. These strata are often most Rqdiocarbon in canyons or gorges which are good sites to find and identify fossils. Understanding the geologic history of an area and the different strata is important to interpreting and understanding archaeological findings.
Chronometric dating methods[ edit ] The majority of chronometric dating methods are radiometric, which means they involve measuring the radioactive decay of a certain chemical isotope. They are called chronometric because they allow one to make a very accurate scientific estimate of the date of an object as expressed in years. They do not, however, give "absolute" dates because they merely provide a statistical probability that a given date falls within a certain range of age expressed in years. Chronometric methods include radiocarbon, potassium-argon, fission-track, and thermoluminescence. The most commonly used chronometic method is radiocarbon analysis. It measures the decay of radioactive carbon 14C that has been absorbed from the atmosphere by a plant or animal prior to its death.
Once the organism dies, the Carbon begins to decay at an extremely predictable rate.
