The deposit thus occurring forms layers depending on the nature of the material brought in by the people inhabiting the area.
According to this method, the upper deposits are younger and the lower deposits are older.
At that time the radioactive disintegration takes over in an uncompensated manner. only half the C-14 will remain after the half-life period.
Further this formula has been disproved on many occasions. Pottery is probably the most abundantly available antique material in any archaeological site.Specimens of organic material which can yield good amount of carbon can be collected for C-14 dating.For example charcoal, wood, shell, paper, leaves, cloth, animal hair, bone, pollen, tooth, iron, prehistoric soot from the ceiling of the caves practically any material containing some carbon can be subjected Bones are generally affected by ground water carbonates and are therefore least reliable for dating.Antiquities and potteries of Roman origin were found in association with the finds of Indian origin.With the aid of these dated imports it was possible to date the associated Indian objects to the first two centuries A. Similarly NBP and PGW has helped in fixing the chronology of numerous sites. Sometimes dates are also obtained with the assistance of astronomy.
