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.
It is nearly always association with other phenomena that gives a first clue as to the use, the age and chronological attribution of a potential datum, but age at least may sometimes be inferred from position in a geological deposit or a layer of peat.
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.
Once a type has been classified by the aid of its context further specimen of the same type, even when found in isolation, can be assigned their place in terms of dates.
Association in simplicity can be illustrated by an example, at the port of Arikamedu near Pondicherry.
Whenever and where ever such antiquities are found, associated finds are automatically dated.
But, for a single culture site the method is quite reliable.However this formula has not been accepted by many archaeologists.Further this formula has been disproved on many occasions. Pottery is probably the most abundantly available antique material in any archaeological site.Sir Flinders Petrie had worked out a formula for dating the finds on the basis of the thickness of the deposit.According to him a period of hundred years may be granted for the accumulation of a deposit of one and a half feet.
