Quaternary malacofauna of Topolovnik and Golubac (north-eastern Serbia)

The paper offers a survey of geological profiles of Quaternary sediments in the neighbourhood of Topolovnik and Golubac. The profiles are composed of loess, loessoid sands, and quicksand. In the area of Topolovik, Quaternary sediments overlying Pliocene sediments contain terrestrial fauna of mollusc s (gastropods). These layers are more than 10 m thick. The neighbourhood of Golubac and the town itself lies partly on Badenian and partly on Quaterna ry formations. The appearance and composition of these sediments can best b e seen on the road cuts near the Danube banks and on the profiles in the wi der area of the town. The Quaternary overlies transgressively the marine Up per Badenian. It is most manifest and best preserved north-west of the stad ium. In the lower part it contains sands 2 m thick with the fauna of fluvia l and terrestrial origin. Overlying them are loess sediments more than 10 m thick, containing terrestrial fauna.
