Sedimentary rock is made of particles derived from other rocks, so measuring isotopes would date the original rock material, not the sediments they have ended up in.However, there are radiometric dating methods that can be used on sedimentary rock, including luminescence dating.The relative dating is the technique to ascertain the age of the artifacts, rocks or even sites while comparing one from the other.In relative dating the exact age of the object is not known; the only thing which made clear using this is that which of the two artifacts is older.

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.

The atoms of some chemical elements have different forms, called isotopes.

These break down over time in a process scientists call radioactive decay.

Because of the fairly fast decay rate of carbon-14, it can only be used on material up to about 60,000 years old.

Geologists use radiocarbon to date such materials as wood and pollen trapped in sediment, which indicates the date of the sediment itself.
