For example, the decay of potassium-40 to argon-40 is used to date rocks older than 20,000 years, and the decay of uranium-238 to lead-206 is used for rocks older than 1 million years.

Radiocarbon dating measures radioactive isotopes in once-living organic material instead of rock, using the decay of carbon-14 to nitrogen-14.

Later, when radiometric absolute dating methods were developed, they still were not applicable to sedimentary layers.Ice core sampling normally uses the assumption that the ring bands observed represents years.One known example where this assumption was used is very misleading.Climate chronology uses evidence of a climatic change, such as an ice age, as a benchmark for dating.states, “Before the 20th century, archaeologists and geologists were largely limited to the use of relative dating techniques.The relative dating methods themselves are generally sound when used with good assumptions. Jesus, the creator and eternal Son of God, who lived a sinless life, loves us so much that He died for our sins, taking the punishment that we deserve, was buried, and rose from the dead according to the Bible.However, when scientists apply relative dating to a preconceived uniformitarianism model, the dating methods are only as good as the model. If you truly believe and trust this in your heart, receiving Jesus alone as your Savior, declaring, "Jesus is Lord," you will be saved from judgment and spend eternity with God in heaven. 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.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.
