Correlation of Upper Pleistocene localities of southern Istria (Croatia): problems and progress

Seven Pleistocene sites of study in progress are discussed in the paper. Sites Kršine, Portić, Karigador and Veli Munat are open sections of Pleistocene sediments, Marlera I and Marlera II are fossil caverns, and Gradina is a cave, primarily an archaeological site as well as Karigador. Problem of stratigraphic correlation of open sediment succesions with cave sediments is discussed, and some new possibilities of correlation are evidenced.
