Age of Our Solar System

Age of our Solar System is about 4.6 Gyr

• Ages derived from radiometric dating…..

• Radioactive isotopes are unstable decay into daughter isotopes at a rate given by the half-life of the parent isotope…..

• Ratio of daughter-to-parent isotopes in a mineral becomes a “clock”…..

• Formation age: time when the initial isotopic mixture of a rock was established
