Problem 30.63 - MC 7 of 10 temperatures in volcanoen drive argon out of solidifying rock and ash, so there is no argon in newly formed material. Alter the rock and ash have completely solidified, however, argon produced in the decay of "K is trapped, so Ar builds up steadly over time. Fairly accurate dating of an object is therefore possible by measuring the ratio of the number of atoms of "Ar to "K in nearby Bevn I Contanta Periodia Tatie Part B- How old is the sample (and therfore the fossil)?
