Dating artifacts done

It is nearly always association with other phenomena that gives a first clue as to the use, the age and chronological attribution of a potential datum, but age at least may sometimes be inferred from position in a geological deposit or a layer of peat.Once a type has been classified by the aid of its context further specimen of the same type, even when found in isolation, can be assigned their place in terms of dates.

By looking at these specific pollen samples as well as the layer of accumulated pollen, researchers can develop a better understanding of the environment and biodiversity throughout the history of an area.

This dating method is also known as Archaeological Dating or Historical Chronology. These methods were relied on especially prior to the introduction of scientific methods of 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.

According to this method, the upper deposits are younger and the lower deposits are older.

Basing on this principle, the cultural assemblages found in different layers can be assigned a chronological personality. In practice it is found that the mounds are disturbed9 by all sorts of pits and dumps.

Ireland’s bogs are full of sediments and pollen, with certain layers linked to events such as the eruption of Icelandic volcanoes in 1104, 1362, and 1510 and an agricultural shift after the Black Death.

By looking at the sedimentary build up of pollen at the microscopic level, 400-1000x magnification, the pollen grains can be identified and the taxa concentrations determined, which can paint a picture of the climate as it changed over time.

Pollen dating, is one of the lesser utilized methods archaeologists have to determine a relative chronology or timeframe for a certain event.
