• Absolute dating techniques can tell the exact age of an artifact by employing various techniques, the most popular being C-14 dating.Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events.In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates (coins and written history).It is clear then that absolute dating is based upon physical and chemical properties of artifacts that provide a clue regarding the true age.

This is possible because properties of rock formations are closely associated with the age of the artifacts found trapped within them.For example, techniques based on isotopes with half lives in the thousands of years, such as Carbon-14, cannot be used to date materials that have ages on the order of billions of years, as the detectable amounts of the radioactive atoms and their decayed daughter isotopes will be too small to measure within the uncertainty of the instruments.One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains.However, age of deposition does not mean the age of artifacts found in that layer.
