20.500.12556/RUL-173049 Sedimentološka in mikropaleontološka analiza Oseškega člena sarmatijske Špiljske formacije v Slovenskih Goricah diplomsko delo Sedimentological and micropaleontological analysis of the Osek Member of the Sarmatian Špilje Formation in Slovenske Gorice diploma work Raziskava obravnava sedimentološko in mikropaleontološko analizo Oseškega člena sarmatijske Špiljske formacije v Slovenskih goricah. V srednjem miocenu je to območje pripadalo Centralni Paratetidi, epikontinentalnemu morju, ki je nastalo po ločitvi od globalnih oceanov zaradi dviga Dinaridov. Kamnine na najdišču Osek-1 so se odlagale v sarmatiju, stopnji poznega srednjega miocena. Sarmatij je zaznamovan z regionalnimi paleogeografskimi spremembami in razvojem endemičnih vrst, kar se odraža tudi v sedimentacijskih procesih na tem območju. Podrobno je preučen sedimentološki profil, ki ga sestavljajo ooidni in bioklastični apnenci z bogato fosilno in mikrofosilno združbo, velikostna porazdelitev in usmerjenost fosilnih hišic polžev ter taksonomska analiza foraminifer. Na podlagi teh analiz je bilo interpretirano paleookolje in sedimentacijski procesi. Rezultati kažejo na visokoenergijsko plitvomorsko okolje z vplivom paleotokov in valovanja, kar se odraža v porazdelitvi in orientaciji fosilnih ostankov ter prisotnosti sedimentnih tekstur, kot je navzkrižna laminacija. Mikropaleontološka analiza foraminifer je pokazala, da je sedimentacija sprva potekala v brakičnih in lagunskih okoljih, nato pa je prišlo do presedimentacije hišic polžev v višje energijsko okolje. Raziskava potrjuje regionalno kontinuiteto sedimentacijskih procesov v sarmatijskem obdobju s primerjavo z drugimi podobnimi nahajališči na območju nekdanje Centralne Paratetide. The research focuses on the sedimentological and micropaleontological analysis of the Osek Member of the Sarmatian Špilje Formation in Slovenske Gorice. In the Middle Miocene, this area was part of the Central Paratethys, an epicontinental sea formed after its separation from global oceans due to the uplift of the Dinarides. The rocks at the Osek-1 site were deposited during the Sarmatian, in the Middle Miocene. The Sarmatian is marked by regional paleogeographic changes and the development of endemic species, which is also reflected in the sedimentary processes of this area. A detailed study was conducted on the sedimentological section, consisting of ooid and bioclastic limestones with a rich fossil and microfossil assemblage. The size distribution and orientation of fossil gastropod shells were determined, and the taxonomic analysis of foraminifera was performed. Based on these analyses, the paleoenvironments and sedimentary processes were interpreted. The results indicate a high-energy, shallow marine environment influenced by paleocurrents and wave action, reflected in the distribution and orientation of fossil remains and the presence of sedimentary structures such as cross-lamination. The micropaleontological analysis of foraminifera revealed that sedimentation initially occurred in brackish and lagoonal environments, followed by resedimentation of gastropods into a more energetic environment. The research confirms the regional continuity of sedimentary processes during the Sarmatian period, by comparison with other similar sites in the former Central Paratethys region.
