Title: Eocene Limestones Overlying Lower Cretaceous Deposits of Western lstria (Croatia): Did Some Parts of Present lstria Form Land During the Cretaceous?
Abstract: In the region of the western Istrian anticline, erosional remains of the transgressive Eocene Foraminiferal limestones overly shallow water deposits of Early Cretaceous age (Valanginian, Hauterivian and Barremian). This evidence, together with the ocurrencc of bauxite deposits and Palaeogene beds overlying Albian, Cenomanian and Senonian limestones indicate the very high relief of the land transgressed by the Palaeogene sea. Contrary to the traditional connection beetween formation of the western Istrian anticline and the Laramian tectonic phase at the end of the Cretaceous (Maastrichtian), new investigations suggest sporadic tectonic movements with constant tectonic coordinate orientation from the Hauterivian to the end of the Cretaceous. With these movements, formation of the anticline structure began in the Early Cretaceous, with the emerged apical parts representing land areas throughout most of the Cretaceous.
