BENTHIC FORAMINIFERA (HOLOCENE) PALEOBIOFACIES OF BOSPHORUS (GOLDEN HORN - SARAYBURNU - ÜSKÜDAR): A NEW APPROACH TO MEDITERRANEAN-BLACK SEA WATERWAY

Abstract

Young sediments in the shelf areas in the sea of Marmara have some faunal signs of Mediterranean transgression, Flandrian, developed following the Vürm period. The evolution of locally tectonic-controlled foraminifera paleobiofacies formed as a result of this transgression 7.5-3.5 thousand years before present in the triple junction between entrance of Bosphorus in Northern Marmara Shelf-Mouth of Golden Horn-Üsküdar indicates that Mediterranean-Black Sea connection in late Quaternary was accomplished over Bosphorus as a result of tectonic-transgression association
