One method of relative dating

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.

Geologists have studied the order in which fossils appeared and disappeared through time and rocks. Fossils can help to match rocks of the same age, even when you find those rocks a long way apart.

The method of reading the order is called stratigraphy (layers of rock are called strata).

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.

Correlation with them has helped geologists date many New Zealand rocks, including those containing dinosaurs.
