This also works with stone tools which are found abundantly at different sites and across long periods of time.

These methods usually analyze physicochemical transformation phenomena whose rate are known or can be estimated relatively well.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.When museums and collectors purchase archaeological items for their collections they enter an expensive and potentially deceptive commercial fine arts arena.Healthy profits are to be made from illicitly plundered ancient sites or selling skillfully made forgeries.
