Add to ORKGA new method for estimating the age of the earth consists of calculating a Pb^207 / Pb^206 age from the observed differences between the isotropic composition of recent lead isolated from the surface of the earth where appreciable concentrations of uranium exist and the isotropic composition of lead isolated from iron meteorites where insignificant concentrations of uranium are found (1-3)
