Geological magazine : Vol. 134 Iss. 1-6 Year. 1997Summary: Radiolarian and calpionellid dating establish a significant sedimentary hiatus within a reduced pelagic sequence of the central part of the Ionian zone (western Greece). Bottom-current activity probably decreased during the Oxfordian, allowing encroachment of radiolarian-rich sediments onto a Jurassic high (at Kato Kouklessi), and then increased again during Kimmeridgian–Tithonian time. The onset of Vigla Limestone sedimentation is diachronous within the Ionian zone, spanning late Tithonian to various levels of early Berriasian time. This diachroneity can be explained by dispersal of fine-grained sediment by current activity.
