The emergence of man through the process of biological and cultural evolution is a story of long span of time.
For the archaeologist and the prehistorian who deals with that long history of man, time is the most important consideration.
In fact, chronology is one of the most fundamental issues in and perhaps a characteristic of archaeology.
Archaeologists use several methods to assign ages to events of the past.
However, instead of the limitations, varve analysis can be used indirectly for archaeological dating.
Carbon dating discovered in 1955, proved very helpful for establishing absolute dating in various archaeological sites.
Potassium-Argon (K40) method extends the range of absolute dating beyond the limit of radio-carbon.
Fission Track Technique - This technique dates material ranging from 20 years to 1,000,000,000 years before the present.
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.
