The age of the earth's crust, calculated from its Rb and Sr content, is (4.5 + or - 1.0) X 10 (super 9) years; an age of (5.1 + or - 0.6) X 10 (super 9) years is calculated from the accumulation of Sr (super 87) in sedimentary rocks. These results yield an average age of (4.8 + or - 0.6) X 10 (super 9) years for the crust.
