Why Is It Difficult To Date Sedimentary Rocks Using

mar 23, 2016 because the elements used for dating need to be re-set by volcanism. radioactive elements decay at a certain constant rate and this is the basis of radiometric dating. but, the decay elements need to be set, much like you would re-set a stop watch for a runner, to ensure an accurate measurement. when minerals get subducted into the earth and come back as volcanic magmas or
