Chronology and dating methods
Advertisement What is Absolute Dating? The absolute dating is the technique to ascertain the exact numerical age of the artifacts, rocks or even sites, with using the methods like carbon dating and other.
To evaluate the exact age, both the chemical and physical properties of the object are looked keenly. The main techniques used in absolute dating are carbon dating, annual cycle method, trapped electron method, and the atomic clocks.
These techniques are more complex and advanced regarding technology as compared to the techniques in practice in the relative dating. The absolute dating is also sometimes referred as the relative numerical dating as it comes with the exact age of the object.
The absolute dating is more reliable than the relative dating, which merely puts the different events in the time order and explains one using the other. The radiometric dating is another crucial technique through which the exact age can be obtained.
In radiometric dating, the radioactive minerals within the rocks are used to know about the age of the object or the sites. Advertisement Relative Dating vs.

Absolute Dating The relative dating is the technique used to know that which object or item is older in comparison to the other one. Contrary to this, the absolute dating is the technique which tells about the exact age of the artifact or the site using the methods like carbon dating.
The absolute dating is also known as the numerical dating as it comes up with the exact numerical age of the item.
In relative dating techniques like stratigraphy and biostratigraphy are used to know which of the object is older. On the other hand, in absolute dating, methods like radiometric dating, carbon dating, and trapped electron method are used.
It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years. The most common relative dating method is stratigraphy. Other methods include fluorine dating, nitrogen dating, association with bones of extinct fauna, association with certain pollen profiles, association with geological features such as beaches, terraces and river meanders, and the establishment of cultural seriations.
Cultural seriations are based on typologies, in which artifacts that are numerous across a wide variety of sites and over time, like pottery or stone tools. If archaeologists know how pottery styles, glazes, and techniques have changed over time they can date sites based on the ratio of different kinds of pottery.
This also works with stone tools which are found abundantly at different sites and across long periods of time.Relative/Absolute Dating
Principle of stratigraphy[ edit ] Stratigraphic dating is based on the principle of depositional superposition of layers of sediments called strata. This principle presumes that the oldest layer of a stratigraphic sequence will be on the bottom and the most recent, or youngest, will be on the top.
The earliest-known hominids in East Africa are often found in very specific stratigraphic contexts that have implications for their relative dating.
These strata are often most visible in canyons or gorges which are good sites to find and identify fossils. Understanding the geologic history of an area and the different strata is important to interpreting and understanding archaeological findings.
Chronometric dating methods[ edit ] The majority of chronometric dating methods are radiometric, which means they involve measuring the radioactive decay of a certain chemical isotope. They are called chronometric because they allow one to make a very accurate scientific estimate of the date of an object as expressed in years.
