Abstract

The growth pattern of fan lobes in the early Pliocene Corfu turbidite system (Greece) demonstrates that regional climatic fluctuations in the land-locked Mediterranean completely concealed global glacioeustatic effects. The temporal evolution of the fan lobes studied closely matches the astronomical precession cycle in this time interval (∼23 ka), strongly suggesting that regular waxing and waning of the sediment supply to the delta-fed turbidite system were directly driven by changes of precipitation and continental runoff. The common lack of high-resolution time control in ancient turbidite systems may lead to mistaken interpretations of higher order cyclicity in ancient turbidite sequences produced by precession-induced variations of sediment supply at low paleolatitudes.
