Archaeological dating important

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.

Charcoal is best material specially if derived from short live plants.Clay tablets found in West Asia contain inscriptional evidence with regard to the occurrence of a solar eclipse.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.The quantity of the C-14 remaining is measured by counting the beta radiation emitted per minute per gram of material.Modern C-14 emits about 15 counts per minute per gram, whereas Carbon-14 which is 5700 years old, emits about 7.5 counts per minute per gram.In such cases subjective element cannot be ruled out.

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.This parallelism is formed due to trade relations, particularly wehen trade followed in both directions.Whenever and where ever such antiquities are found, associated finds are automatically dated.For example Mauryan terracottas, Roman amphorae, Harappan pottery, NBP , PGW,etc.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.
