This closely agrees with the fact that the seals from Indus Valley style from Ur, Kish and Tell Asmar and other sites fall within the range of 2500-1500 B. When a group or type of objects are found together under circumstances suggesting contemporanity they are said to be associated.

But, for a single culture site the method is quite reliable.At that time the radioactive disintegration takes over in an uncompensated manner. only half the C-14 will remain after the half-life period.In the disintegration process the Carbon-14 returns to nitrogen emitting a beta particle in the process.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.

Astronomical data have been applied in the study of geological ice ages by calculating the curves for major fluctuation of solar radiation.
