Abstract

A boxcore taken from the top of a seamount south of Crete, on the outer (south) side of the Hellenic Trench, contains allochtonous coarse clastics, consisting mainly of rock fragments of alpine basement, brecciated Early/Middle Pliocene marls and reworked older Neogene sediments. This mixture of lithologies is interpreted as an Early/Middle Pliocene mass-flow deposit, which can be correlated with similar deposits from adjoining on- and offshore areas. The wide distribution of these sediments may be related to a period of increased tectonic activity which caused substantial vertical movements in the south Hellenic Arc. It is concluded that at the time of the formation of the mass-flow deposits this part of the Hellenic Trench had not yet evolved.
