Middle Miocene deposits in the area of Sv Nedelja
Studied sequence of 1.4 m thick laminated marls is located at Svetonedeljski breg 20 km southwest of Zagreb. Three lithologically different samples were processed by sieving method. The lowermost part of the section is 22 cm thick, with 2 – 3 cm thick light-coloured beds (Facies A). These lime-rich marls contain rich and diverse fossil assemblage of small benthic foraminifera, ostracods and macrofossil remains (fish teeth, molluscs). Foraminiferal association is dominated by rotaliids, with small number of miliolids. Central part of the section (Facies B) is ca. 41 cm thick and represented by argillaceous brown thin bedded marls (bed thickness 0.5 – 2 cm). Fossil assemblage is less abundant and diverse, but better preserved. Ostracods are absent, and Elphidum species dominate. Uppermost part of the section, 99 cm thick, is again composed of lime-rich marls (Facies C) (3 – 5 cm thick beds). Fossil association is poorly preserved, but it contains diverse fauna of foraminifera, ostracods, fish (teeth and scales), molluscs and serpulids. Spiny Elphidium species, and the presence of Anomalinoides dividens suggest the deposition during the Badenian/Sarmatian transition (FILIPESCU, 2004 ; VRSALJKO et al., 2005 ; FILIPESCU et al., 2014). Marls were deposited in inner shelf marine environment, with phreatic conditions in Facies A and C (dissolution and/or cementation traces). Deposition of argillaceous marls (Facies B) took place during the increased input of terrigenous material. Mode of deposition possibly reflects seasonal changes.
