Dating methods in archaeology establish the time and sequence of events that created archaeological deposits and layers, called strata, within those deposits. Absolute dating relies on biological, chemical (radiometric), geological/electromagnetic, or historical investigation to obtain the date range of a deposit.

In social sciences there are many key concepts and terms that are crucial for students to know and understand.Often it can be hard to determine what the most important social sciences concepts and terms are, and even once you’ve identified them you still need to understand what they mean.To help you learn and understand key social sciences terms and concepts, we’ve identified some of the most important ones and provided detailed definitions for them, written and compiled by Chegg experts.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.But, even when the scientific methods of absolute dating are available, this method of dating has not lost its importance, as many a time we have to depend solely on relative dating.

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.

The deposit thus occurring forms layers depending on the nature of the material brought in by the people inhabiting the area.

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.

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.
