Did you know?
WebSo assuming that when a rock forms it contains an unstable isotope and none of the daughter isotope (or a well-known amount), and assuming that over geologic time the rock remains a closed system (no parent or daughter enters or leaves the rock), then that rock can be accurately dated by determining the ratio of parent to daughter atoms. http://www.columbia.edu/~vjd1/radiometric_dating.htm

The mathematical expression from which the isochron is derived is where t is age of the sample, D* is number of atoms of the radiogenic daughter isotope in the sample, D0 is number of atoms of the daughter isotope in the original or initial composition, n is number of atoms of the parent isotope in the sample at the present, λ is the decay constant of the parent is…
WebJun 4, 2024 · Scientists interested in figuring out the age of a fossil or rock analyze a sample to determine the ratio of a given radioactive element's daughter isotope (or isotopes) to its parent isotope in that sample. Mathematically, from the above equations, this is N/N 0.
