Radioactive isotopes radiometric dating

This is an enormous branch of geochemistry called Geochronology.

It is an accurate way to date specific geologic events.

Because geochronologists want to measure isotopes with different masses, a mass spectrometer works really well for dating things.

I do think that radiometric dating is an accurate way to date the earth, although I am a geochronologist so I have my biases.

So, when the materials are appropriate and one carefully avoids contamination and re setting radiometric clocks can be VERY ACCURATE.This is why crystals are good for radiometric dating: the atoms in a crystal are extremely efficiently packed, and it's very difficult to get anything into a crystal such as a contaminant by any means short of destroying the crystal and re-growing it anew.
