The application of varve dating is restricted by several factors.First, it is because varve accumulation occurs only to glacial areas of the world.Fission track dating is based upon the fact that over geological time spontaneous fission of uranium-238 impurities produces minute sub- microscopic damage trails in the most insulating solids, both long period of time.As the damage sites are permanent, a simple count of their number allows an age to be measured.

It has been used in Baltic area, North America, South America and Africa.

Chronology, the study of events in time frame, is hence the central theme of archaeologist, like the geologist who deals with the story of earth history.

In fact, chronology is one of the most fundamental issues in and perhaps a characteristic of archaeology.

Thus the age of the skeletal materials that are found in archaeological sites can be estimated by determining the amount of change, racemisation that has occurred.

Amino Acid Racemisation (AAR) is a useful comparative dating method with great potential, but it introduces problems of calibration and the requirement of an intimate knowledge of the palaeoenvironmental conditions of the bone deposition site.

The longest sequence known goes back only 17,000 years.
