Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.

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.

It is also possible to use it on authigenic minerals, such as glauconite, in some sedimentary rocks.

Radiometric dating of minerals in metamorphic rocks usually indicates the age of the metamorphism.

This is different to relative dating, which only puts geological events in time Most absolute dates for rocks are obtained with radiometric methods.
