Connecting with tephras: principles, functioning, and applications of tephrochronology in Quaternary science [PDF]

open access: yes, 2013
Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic, or archaeological sequences or events. The method relies firstly on stratigraphy and the law of superposition, which apply in any study that connects
