WebChronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time. Archaeologists and scientists use absolute dating methods on samples ranging from prehistoric fossils to artifacts from relatively recent history. WebYou can use a mixture of chronometric and relative dating methods to accomplish this task. When using chronometric methods, you will send a sample off to a lab (i.e., the instructor) which will provide you with the results of the analysis. The lab can handle radiocarbon, potassium-argon, and argon-argon requests.
