Tephrochronology and its application: A review [PDF]

open access: yesQuaternary Geochronology, 2011
Abstract Tephrochronology (from tephra , Gk ‘ashes’) is a unique stratigraphic method for linking, dating, and synchronizing geological, palaeoenvironmental, or archaeological sequences or events. As well as utilizing the Law of Superposition, tephrochronology in practise requires tephra deposits to be characterized (or ‘fingerprinted’) using ...
