Start studying chapter 6 rocks and fossils when rock layers slant by earth's internal which radiometric dating method would be used to date . Why can't most sedimentary rocks be dated layers of the sedimentary rock use carbon-14 radiometric dating for sedimentary rock younger than 50,000 years . Most of the chronometric dating methods in use today are radiometric t he potassium-argon and argon-argon method s are used to date volcanic rock and ash deposits.

Fossils: how fossils are dated fiona a good way of guessing the range is to look at the layers of rock that were radioactive dating . 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).
Examples of dating methods for igneous rocks previously, dating of anthropology sites had to rely on dating of geologic layers above and below the artifacts. Any method of determining whether an event radiometric dating has been done on rocks and meteorites index fossils are used to date rock layers in .
