QUANTITATIVE AND QUALITATIVE ANALYSIS OF FORAMINIFERA IN THE MIDDLE MIOCENE OF SALT DEPOSIT TETIMA (NORTH-EAST BOSNIA)
Roč.20,č.1-2(2013)
Based on samples taken from the exploratory borehole B-71 were carried out qualitative and quantitative micropaleontological research aimed at determining the stratigraphic levels overlying sediments, and the frequency and abundance of foraminifera in isolated areas. Research of foraminifera has been performed on 98 samples. Biostratigraphic analysis of overlying sediments of salt formation was made to the relevant Badenian and Sarmatian Zone. According to foraminifera it was done the detailed stratigraphic division and proved the Lower, Middle, Upper Badenian and Lower Sarmatian. Lower Badenian is divided into two zones: Ammonia viennensis and Nonion commune Zone (older part) and Globigerinoides trilobus and Orbulina suturalis Zone (younger part). Middle Badenian is represented by of Pappina parkeri Zone while the Upper Badenian is represented by Bolivina dilatata maxima Zone. Th e Lower Sarmatian is presented by two zones: Elphidium hauerinum Zone and younger Porosononion granosum Zone.
