Abstract

Fallout tephra layers from powerful explosive eruptions are isochronous marker beds, which can be used to correlate, and possibly to date, quaternary marine and continental sedimentary sequences, even if at a great distance from one another. It can thus be said that tephrachronology is a useful tool for the reconstruction of natural events over wide areas, particularly in non-volcanic regions. General principles of the tephrochronological method and main techniques of investigation, both in the field and in laboratory, as desumed from the up-to-date bibliography, are outlined in this paper; results of those tephra studies which are of interest for the Italian context are reported. These mostly concern deep-sea records; in spite of their potentiality in areas adjacent to the Italian quaternary explosive volcanoes, tephra studies have been scarsely carried out until now in terrestrial deposits.
