We need to see the data to know if there is really any need to explain anything away.

So we are investing a lot of time and energy to explain how this marvelous agreement of the various methods can arise in a creationist framework. What has to happen next to get an isochron is that the uranium or thorium has to concentrate relative to the lead isotopes, more in some places than others. Once the rocks melt, a plume of molten material begins to rise in the crust. These isotopes differ in the number of neutrons they have in their nuclei.
