the 'fossil' tracks counted) viz., exposes the sample to a known number of low energy (thermal)neutrons which induce fission of a small fraction of the uranium atoms in the sample.The sample is immersed in the proper chemical reagent, which allows rapid attack of the narrow regions of damage and slower dissolution of the adjacent unchanged material.

The density of track depends on the uranium content as well as the age of the sample (i.e.

They are engaged in defining the stages of hominid evolution and their artifactual record, and the assignment of a chronology to these stages.

Chronology is the science of measuring time and ordering of the things in time.

According to the Dictionary of Anthropology, the word chronology means the science of computing dates or treaties showing arrangement of events with dates.

In other words, Chronology is the arrangement of events, or the materials which represent them, in the order of their occurrence in time.

Such treatment are used to create etch pits of optical size, each one making a single fission site.

The method requires sufficient uranium to produce a track density, which can be counted within reasonable time.

Any study of the origins of human must be set in a chronological context.

The application of varve dating is restricted by several factors.

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.

The sequence of development of culture or the relationship between events that represent culture can be established only when events can be placed in proper time.
