A piece of the mineral zircon is found to contain a Pb-206:U-238 ratio of 0.213 g:1.00 g. Assuming all Pb-206 in the sample is attributable to decay of U-236 (a good assumption as lead is otherwise rarely incorporated into the crystal structure of zircon), how old is the mineral sample? The half life of U-238 is 4.5 Ã- 109 years.
