URANIUM - Bassam Shakhashiri

the oldest uranium-bearing rocks, the ratio of U-238 to Pb-206 is about 1-to-1. Therefore, half of the original U-238 has decayed to Pb-206 and the rock is as old as one half life of U-238. At least two other radioactive clocks are used for dating geological time spans. These are the potassium to argon and rubidium to strontium transformations.
