Abstract

Unutar ovog rada istraživano je područje slane močvare kod Jadrtovca (srednja Dalmacija) bušenjem četiri sedimentne jezgre duž profila slane močvare. Sediment iz jezgri podijeljen je na intervale, laboratorijski obrađen, određene su mu sedimentološke karakteristike, nakon čega je podvrgnut metodi razgradnje organske tvari pomoću 30%‑tne otopine vodikovog peroksida. Potom je uslijedila detaljna mikropaleontološka analiza pod stereoskopskim mikroskopom. Svi uzorci su pregledani i izdvojena im je... More foraminiferska zajednica. Foraminifere su određene prema rodu ili vrsti. Sediment je u konačnici klasificiran kao mulj s manjim udjelima pijeska i šljunka. Od foraminiferske zajednice dominiraju bentičke, perforatne foraminifere Opažene planktonske foraminifere uglavnom su pretaložene iz fliškog zaleđa. Objašnjen je nastanak slane močvare i promjene taložnih okoliša te pomoću prisutnosti antropogenog materijala, okvirna starost sedimenta jezgre do jednog metra. Less

Abstract (english)

In this thesis, the area of the salt marsh near Jadrtovac (Central Dalmatia) was investigated by drilling four sedimentary cores along the profile of the salt marsh. The sediment from the cores was divided into intervals, laboratory processed. Its sedimentological characteristics were determined, after which it was subjected to the method of decomposition of organic matter using a 30% solution of hydrogen peroxide. This was followed by a detailed micropaleontological analysis under a... More stereoscopic microscope. All samples were examined and their foraminiferal assemblage was isolated. Foraminifera were defined by genus or species. The sediment is ultimately classified as mud with smaller amount of sand and gravel fractions. The foraminiferal assemblage is dominated by benthic and perforated foraminifera. Detected planktonic foraminifera were mainly redeposited from the flysch hinterland. The genesis of the salt marsh and changes in depositional environments alongside the approximate age of the core sediment up to one meter is explained. Less
