Description
Summary:The late Miocene sediments of the Tyrrhenian ODP Site 654 encompass a deepening sequence which begins with glauconite shallow water sands followed by a rapid transition to deep water sediments and culminates with dolomitic mudstones associated with Messinian evaporites. The sequence compares well with the so-called 'Sahelian cycle' and with post-orogenic cycles recognized in peninsular Italy and Sicily. The studied interval, consisting of 55 m thick nannofossil oozes, belongs to the Globorotalia suterae subzone and lower part of the Globorotalia conomiozea Zone, indicating late Tortonian and early Messinian age, respectively. Biomagnetostratigraphic correlation assigns the Tortonian/ Messinian boundary an age of 6.44-6.45 Ma. In addition, six main events have been recognized, based on the range of keeled globorotaliids and coiling direction changes of keeled and unkeeled globorotaliids, which have been correlated to the geomagnetic time-scale. Comparison with North Atlantic sites and land sections of the ... : Supplement to: Glacon, Georgette; Vergnaud-Grazzini, Colette; Iaccarino, Silvia Maria; Réhault, Jean-Pierre; Randrianasolo, Auran; Sierro, Francisco Javier; Weaver, Philip PE; Channell, James E T; Torii, Masayuki; Hawthorne, Teresa B (1990): Planktonic foraminiferal events and stable isotope records in the Upper Miocene, Site 654.
