Chart of a few different isotope half lifes: In reality, geologists tend to mix and match relative and absolute age dates to piece together a geologic history.If a rock has been partially melted, or otherwise metamorphosed, that causes complications for radiometric (absolute) age dating as well.Here is an easy-to understand analogy for your students: relative age dating is like saying that your grandfather is older than you.

Geologists draw on it and other basic principles ( to determine the relative ages of rocks or features such as faults.That’s because zircon is super tough – it resists weathering. Each radioactive isotope works best for particular applications.The half-life of carbon 14, for example, is 5,730 years.For example, which is older, the bricks in a building or the building itself?

Are there repairs or cracks in the sidewalk that came after the sidewalk was built?

Though still heavily used, relative dating is now augmented by several modern dating techniques.
