Dating ancient objects

Although it sometimes requires taking minute samples of an object, even that damage may be unacceptable for some artifacts.The new method does not involve removing a sample of the object.

Limits to relative dating are that it cannot provide an accurate year or a specific date of use.

SAN FRANCISCO, March 23, 2010 — Scientists today described development of a new method to determine the age of ancient mummies, old artwork, and other relics without causing damage to these treasures of global cultural heritage.

Reporting at the 239th National Meeting of the American Chemical Society (ACS), they said it could allow scientific analysis of hundreds of artifacts that until now were off limits because museums and private collectors did not want the objects damaged.

The following is a list of dating techniques used in archaeology and other sciences. Stratigraphy Stratigraphy is the most basic and intuitive dating technique and is therefore also the oldest of the relative dating techniques.

It is more or less in the order of discovery of each procedure. Based on the law of Superposition, stratigraphy states that lower layers should be older than layers closer to the surface, and in the world of archaeology this is generally the case, unless some natural or manmade event has literally mixed up the layers in some fashion.
