Basing on this principle, the cultural assemblages found in different layers can be assigned a chronological personality. In practice it is found that the mounds are disturbed9 by all sorts of pits and dumps.For example, if the cultural contents of the lower deposit are Mauryan in character, appropriately this deposit may be assigned a date between 400-200 B. Similarly, if the cultural equipment of the upper deposit are of the Sunga period, this deposit has to placed between 200-73 B. Quite often, the archaeologist decided the change of stratum on the basis of the feed of the deposit.Different methods have their own limitations, especially with regard to the age range they can measure and the substances they can date.A common problem with any dating method is that a sample may be contaminated with older or younger material and give a false age.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.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.

These include radiometric dating of volcanic layers above or below the fossils or by comparisons to similar rocks and fossils of known ages.

This problem is now reduced by the careful collection of samples, rigorous crosschecking and the use of newer techniques that can date minute samples.

Volcanic rocks – such as tuff and basalt – can be used in dating because they are formed at a particular moment in time, during an eruption.

In such cases subjective element cannot be ruled out.

But, for a single culture site the method is quite reliable.
