12 Potassium-40 is a naturally occurring radioactive isotope often used to date minerals. It undergoes electron capture to form Ar-40 with a half life of 1.28 x 109 years. If a mineral is found to have 79.456% of the K-40 still as K-40 (20.544% has converted to Ar-40) and assuming that all of the argon produced remains in the mineral, how long ago did it crystallize from magma e argon prodaced Kl ielo
