Geologists often need to know the age of material that they find.They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.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.For example, fission track dating measures the microscopic marks left in crystals by subatomic particles from decaying isotopes.

Contrary to this, absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.Relative Dating and Absolute Dating are two types of such techniques which are under practice to determine the age of the fossils, objects or civilizations.The relative dating is the technique in the Geology through which the age is determined with relation to the other objects.These rates of decay are known, so if you can measure the proportion of parent and daughter isotopes in rocks now, you can calculate when the rocks were formed.Because of their unique decay rates, different elements are used for dating different age ranges.
