1. Upper Miocene ostracods from the Krško Basin, SE SloveniaMiha Marinšek, Valentina Hajek-Tadesse, Marijan Poljak, Tea Kolar-Jurkovšek, Luka Gale, 2023, original scientific article Abstract: The purpose of this study was to identify the ostracod assemblage from a 43 m thick section of
the Bizeljsko Formation, which constitutes the middle part of the Upper Miocene Posavje Group.
The succession comprises sandstone, siltstone, and marlstone, deposited in a delta front environment. The determined ostracods belong to the families Cyprididae, Cytheridae, Darwinulidae, and Loxoconchidae. In total, 30 species were identified. Additionally, 8 morphotypes were determined at the genus level. The most common genera are Candona, Hemicytheria, and Cyprideis. The assemblage belongs to the Caspiocypris labiata subzone from the upper Pannonian.
The ostracod assemblage from the Krško Basin is similar in species composition to Pannonian ostracod assemblages from Croatia and Serbia.

2. GPR survey to reveal a possible tectonic tilt of the Brežice Sava River Terrace in the Krško BasinMarjana Zajc, Marijan Poljak, Andrej Gosar, 2021, original scientific article Abstract: It has been supposed that the Brežice Sava River Terrace (BSRT) is tectonically disturbed near the town of Brežice and tilted to the north. To confirm this tectonically induced tilt in a quantitative sense, low-frequency Ground Penetration Radar (GPR) was applied. A total of eight GPR profiles were recorded across the BSRT providing information of the lower boundary of the terrace, which consists of loose to poorly cemented Quaternary gravel, while its Tertiary basement consists of poorly cemented carbonaceous silt (marl). The premise of the study was the assumption that this lithological boundary could be detected by the GPR method. In addition to the upper surface of the BSRT being tilted to the north by 0.18°, GPR profiles also showed a 0.04° difference in the tilt between the upper surface of the terrace and its lower boundary with the basement, which we assigned to the sin-sedimentary tilt. Upon this information, a cumulative tectonically induced dip of the BSRT lower boundary was defined at 0.22°.
