Web12 sep. 2024 · Absolute dating. By measuring the rate of radioactive decay, a technique known as absolute dating or radiometric dating can be used to determine the age of rocks. An unstable daughter isotope is created by the radioactive isotope in the rock decaying. The sample's age could be determined because the decay happens at a predictable rate. WebNeodymium-143. 106 billion years. The mathematical expression that relates radioactive decay to geologic time is called the age equation and is: t=1/delta ln (1 + D/P) where: t is the age of a rock or mineral specimen, D is the number of atoms of a daughter product today, P is the number of atoms of the parent product today,
