With absolute age dating, scientists determine the absolute age of a rock in millions of years before present rather than just the age of the rock relative to the rock units around it. Absolute dating, also known as chronometric dating, assigns numerical age in years to fossils and rocks based on the physical and chemical properties of materials in rock. There are three types: 1. Radio-metric dating: Based on the predictable rates of decay of naturally occurring radioactive isotopes which are present in rock or fossil.Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.

This evidence makes it clear that life is very old and places a timescale on the pace of evolutionary change, diversification, and extinction. Ammonite fossil. Relative dating; Numeric (or absolute) dating, Relative Dating . Relative age dating determines the order in which a sequence of geologic events occurred (e.g., bottom-to-top sequential deposition of sedimentary strata, then carving of a geologically young canyon through those strata), but cannot determine how long ago events happened. Numeric Ages By dating these surrounding layers, they can figure out the youngest and oldest that the fossil might be; this is known as “bracketing” the age of the sedimentary layer in which the fossils occur. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
