Dating rocks using radioactive isotopes interfaith dating muslim

Using relative dating the fossil is compared to something for which an age is already known.For example if you have a fossil trilobite and it was found in the Wheeler Formation.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.

There are over forty such techniques, each using a different radioactive element or a different way of measuring them.

When ‘parent’ uranium-238 decays, for example, it produces subatomic particles, energy and ‘daughter’ lead-206.

Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.

There are two main methods determining a fossils age, relative dating and absolute dating.

Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.
