In the lab, samples are heated releasing the trapped electrons and producing light. Thermoluminescent dating is used to date archeological deposits, detect ceramic fakes in art collections, and even date burned flint artifacts.
Seriation is a relative dating method that is used to place types of artifacts (or sites with certain artifact types) into a chronological sequence.Adding the margin of error for carbon-14 (in this case, /- 150 years), the archaeologist can give a reliable date range for the bone: 1655-1405 B. A bone found deep in the ground will generally be older than one found close to the surface, for example.Two bones found in the same archaeological deposit are likely to be the same age.The abundance of decorated ceramics from the park will be helpful in fixing the time of occupation.
Ceramic samples will be subjected to mineralogical analysis to determine whether or not they were made of local clays.All living beings, both plants and animals, have a mixture of radioactive C-14 and nonradioactive C-12 atoms in their organic material. The remaining C-14 atoms decay at a constant rate, allowing this process to be used reliably as an indicator of age.
