Potassium isotope dating
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.You may now see our list and photos of women who are in your area and meet your preferences.Again, please keep their identity a secret Click on the "Continue" button search with your zip/postal code.Others measure the subatomic particles that are emitted as an isotope decays.Some measure the decay of isotopes more indirectly.
Because of their unique decay rates, different elements are used for dating different age ranges.
All radiometric dating methods measure isotopes in some way.
Most directly measure the amount of isotopes in rocks, using a mass spectrometer.
Because of the fairly fast decay rate of carbon-14, it can only be used on material up to about 60,000 years old.
Geologists use radiocarbon to date such materials as wood and pollen trapped in sediment, which indicates the date of the sediment itself.
