Dating archaeological deposits dating sites for cutters
For example Mauryan terracottas, Roman amphorae, Harappan pottery, NBP , PGW,etc.Sir Flinders Petrie had worked out a formula for dating the finds on the basis of the thickness of the deposit.
The quantity of the C-14 remaining is measured by counting the beta radiation emitted per minute per gram of material.But, for a single culture site the method is quite reliable.Quite convincing dates are sometimes arrived at by importing parallels from other contemporaneous cultures.Specialists in the field of astronomical research placed this solar eclipse as on 15 June 763 B. The Almanac belonging to Maya culture of Central America helped in dating several important sites accurately on the basis of astronomy.
Astronomical data have been applied in the study of geological ice ages by calculating the curves for major fluctuation of solar radiation.This parallelism is formed due to trade relations, particularly wehen trade followed in both directions.
