dating (sh)




In geology and archaeology, the process of determining an object's or event's place within a chronological scheme.

Scientists may use either relative Dating, in which items are sequenced on the basis of stratigraphic clues (see stratigraphy) or a presumed evolution in form or structure, or absolute Dating, in which items are assigned a date independent of context. The latter type includes potassium-argon and carbon-14 Dating; both are based on the measurement of radioactive decay. The record of changes in polarity of the Earth's magnetic field has provided a timescale for seafloor spreading and long-term marine sedimentation. Dendrochronology has proved useful in archaeology and climatology.
