Absolute and relative dating techniques
Geological specimens that are unearthed need to be assigned an appropriate age.
To find their age, two major geological dating methods are used.
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.
Other than rocks, fossils are the other most important elements in relative dating as many organisms have there remain in the sedimentary rocks.The following are the major methods of relative dating.Stratigraphy: The oldest dating method which studies the successive placement of layers.Faunal deposits include remains and fossils of dead animals.
Cross dating: This method compares the age of remains or fossils found in a layer with the ones found in other layers.To evaluate the exact age, both the chemical and physical properties of the object are looked keenly.
