Prior to the development of radiometric methods of dating rocks, the ages of rocks and other geologic features could not be expressed quantitatively, or as numbers of years, but instead were expressed solely in terms of relative ages, in which the age of a particular geologic feature could be expressed as relatively younger or older than other geologic features.

With the aid of various radiometric methods involving mass spectrometric analysis, researchers have found it possible to determine how long ago a particular sediment was deposited, when an igneous rock crystallized or when a metamorphic rock recrystallized, and even the time at which rocks in a mountain belt cooled or underwent uplift.

Radiometric methods provide an accurate approach to dating such ancient sediments.
