Dating in archaeology a guide to scientific techniques
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.Archaeological Dating Methods introduces students to many of the more common dating methods used or found in related literature.Most of the summarized dating methods may not be used with regularity in the field, but individuals should be informed about their existence, usefulness, and sample collection methods.
Even when the absolute dates are available, we have to supplement the information with relative dating.
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.
In such cases subjective element cannot be ruled out.
