A New Discovery of the Lower Cretaceous in İstanbul, Turkey

Abstract

Limestone-pebble conglomerates in the Kocaeli Peninsula have so far been widely accepted as either Triassic carbonates or basal elastics of the Upper Cretaceous. New evidence of age and stratigraphic relations indicate that part of the conglomerate, together with some shale and coralgal limestone units, formerly considered as being Triassic, is early Cretaceous in age.
