Chronometric 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.

Which dating Chronometric technique can be used?

Chronometric dating methods Chronometric methods include radiocarbon, potassium-argon, fission-track, and thermoluminescence. The most commonly used chronometic method is radiocarbon analysis.

What is radiometric dating and how is it used?

Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e.g., carbon-14, or a long-life radioactive element plus its decay product, e.g., potassium-14/argon-40.

What chronometric dating method would you use to date this layer?

The leading chronometric method for archaeology is radiocarbon dating (Figure 7.32). This method is based on the decay of 14C, which is an unstable isotope of carbon.
