Sažetak
Depositional environments with pelagic limestones have been studied from three localities in southwestern part of the Adriatic carbonate platform. (Sections) Profiles on Ist, Premuda and Silba islands allow us to reconstruct paleogeographical and paleoenvironmental conditions of investigated part of the carbonate platform during the Senonian. In the studied sections Ist and Premuda, two lithotypes vertically exchange: (1) pelagic mudstones-packstones with intercalations of shallow water material (predominately rudist floatstone and wackestones-packstones, rarely grainstones with benthic fossils) and, (2) laminated mud supported limestones with pelagic fossils. According to the proximity of the shallow water carbonate platform interior (Moro & Jelaska, 1994) the depositional setting of analyzed sediments could be considered as platform-open sea transect with two major sedimentary groups: pelagic carbonates and resedimented shallow water carbonates (Flugel, 2004). Depositional environments of Ist and Premuda profiles could be interpreted as of more distal origin, while Silba profile represents more proximal part of the transect sediments. Paleogeographically, depositional environments of these sediments, indicate that more open and relatively deeper depositional environments characterized the SW part of the Adriatic carbonate platform.
