In the field of Geology, dating is an important term as it is a technique through which evaluation regarding the age and period about the fossil, remains, the archaeologists do valuables and artifacts.

At first, there were not many methods of dating were available, but now with advancement in the technology, we mainly have two types of techniques to ascertain ages of ancient belongings.

This evaluation of the rocks and fossils in relative dating is known as the biostratigraphy.

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.

Most commonly, the ancient factors of the rocks or objects are examined using the method called stratigraphy.

In other words, we can say that the age in relative dating is ascertained by witnessing the layers of deposition or the rocks.

For organic materials, the comparison is between the current ratio of a radioactive isotope to a stable isotope of the same element and the known ratio of the two isotopes in living organisms.

Radiocarbon dating is one such type of radiometric dating.

In relative dating, mostly the common sense principles are applied, and it is told that which artifact or object is older than the other one.

In other words, we can say that in relative dating the archaeologist determines that which of the two fossil or the artifacts are older.

Contrary to this, absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.

For inorganic materials, such as rocks containing the radioactive isotope rubidium, the amount of the isotope in the object is compared to the amount of the isotope's decay products (in this case strontium).

The object's approximate age can then be figured out using the known rate of decay of the isotope.
