Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.
Plus, get practice tests, quizzes, and personalized coaching to help you succeed.It is important to remember that this method give the age of the mineral, not the artifact.So we can't pick up an artifact that's made from volcanic rock and get a potassium argon date on the artifact.However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.So, we rely on radiometric dating to calculate their ages.Relative dating methods do not tell archaeologists exactly how old things are, but only how old things are relative to each other.
Archaeologists work on the principle that objects at the bottom of an undisturbed were put there before objects that are above them, so objects found in the lower levels of a site are usually older than objects found in higher levels.
We wouldn''t be dating the artifact – we'd be dating the rock and the rock might have formed millions of years earlier.

These assumptions are not demonstrated, only supposed to be true.
To give an example of the complexity of this problem, this paper presents a study of the most popular dating method, potassium/argon.
