During the alpha decay steps, the zircon crystal experiences radiation damage, associated with each alpha decay.

This damage is most concentrated around the parent isotope (U and Th), expelling the daughter isotope (Pb) from its original position in the zircon lattice.

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.

Since the exact rate at which uranium decays into lead is known, the current ratio of lead to uranium in a sample of the mineral can be used to reliably determine its age.

The method relies on two separate decay chains, the uranium series from Pb) leads to multiple dating techniques within the overall U–Pb system.

and most refined of the radiometric dating schemes.Relative dating is a less advanced technique as compared to absolute 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.These techniques are more complex and advanced regarding technology as compared to the techniques in practice in relative dating.The absolute dating is also sometimes referred to as the relative numerical dating as it comes with the exact age of the object.
