UExcel Earth Science: Most commonly, the ancient factors of the rocks or objects are examined using the method called stratigraphy. Using radiometric dates and measurements of the ancient magnetic polarity in volcanic and sedimentary rocks termed paleomagnetismgeologists have been able to determine precisely when magnetic reversals occurred in the past.
