Best method for dating rocks
The best way to obtain a numerical age for a sedimentary rock – other than through comparison of fossil content or magnetopolarity reversals with the geological timescale – is through the direct dating of volcanic ash layers (u-pb and ar-ar techniques on mineral separates).
