If the solar system formed from a common pool of matter, which was uniformly distributed in terms of Pb isotope ratios, then the initial plots for all objects from that pool of matter would fall on a single point.
Over time, the amounts of Pb-206 and Pb-207 will change in some samples, as these isotopes are decay end-products of uranium decay (U-238 decays to Pb-206, and U-235 decays to Pb-207).
This causes the data points to separate from each other.
The higher the uranium-to-lead ratio of a rock, the more the Pb-206/Pb-204 and Pb-207/Pb-204 values will change with time.
This value is derived from several different lines of evidence.
Unfortunately, the age cannot be computed directly from material that is solely from the Earth.
Myth has always been supportive of this thinking and when you refer to any prevailing myths of any time you can see that there has always been a case for immortality being the one thing that would elude man for ever. Not only are they seemingly immortal, they also are perfect - rather like some perfectionist’s superego (sic). thus a fairy helps out damsels in distress(Cinderella for example) because she feels benevolent towards ill treated people…
See the Isochron Dating FAQ or Faure (1986, chapter 18) for technical detail.
A young-Earther would object to all of the "assumptions" listed above.
This involves measurement of three isotopes of lead (Pb-206, Pb-207, and either Pb-208 or Pb-204).
A plot is constructed of Pb-206/Pb-204 versus Pb-207/Pb-204.
Of the more prevalent myths - which have captivated the attention of so many millions, are immortal villains like vampires, werewolves, ghosts, ghouls, demons, sorcerers... and demons inevitably have to conquer everything that is because they are drunk with power.
