A newly recognized 2-m-thick trachytic volcanic ash deposit from north
western Greece is dated at 374,000 +/- 7000 yr and correlated with the
Middle Pleistocene volcanic activity of central Italy. The deposit re
presents ash fallout from one of the largest volcanic eruptions in Eur
ope of the past 400,000 yr and should provide an important stratigraph
ic marker within the poorly dated Middle Pleistocene deposits of Italy
and Greece. (C) 1998 University of Washington.
