Dating methods stone tools
Astronomical data have been applied in the study of geological ice ages by calculating the curves for major fluctuation of solar radiation.
Consequently, the chronology worked out for the geological deposits helped in dating the prehistoric tools found in these deposits. There are certain antiquities and potteries which by themselves have acquired a dating value.
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.
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.
For example Mauryan terracottas, Roman amphorae, Harappan pottery, NBP , PGW,etc.
Even when the absolute dates are available, we have to supplement the information with relative dating.
The various methods of relative dating are; This method depends on the common observation that the height of the habitational area increases as the people continue to live at the same place.
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.
