AB  - A combined inorganic and organic geochemical study was carried out on marls and mudstones collected from the Lower Miocene Lopare Basin, Bosnia and Herzegovina. A total of 46 samples collected from two boreholes, Pot 1 (depth of 193 m) and Pot 3 (depth of 344 m), showed that element abundances like boron (B), lithium (Li), strontium (Sr), uranium (U), chromium (Cr), nickel (Ni), magnesium (Mg), sodium (Na) and calcium (Ca) are much higher than average than in the upper continental crust (UCC). Chemical composition indicates at least two sources: (i) Mesozoic ophiolites occurring in the north of the investigated area, and (ii) dacito-andesitic pyroclastics (Mesozoic to Cenozoic). Lopare Basin sedimentation was influenced by strong evaporation resulting in a partly hypersaline lake, which formed during a warm climatic period, probably during the Miocene Climatic Optimum. A brief episode of humid climate conditions resulted in the basin filling-up and deposition of felsic sediments enriched in thorium (Th). Organic geochemistry shows that the majority of studied sediments contains predominantly immature to marginally mature algal organic matter (OM). The biomarker patterns are generally in agreement with the geological history of the Lopare Basin and inorganic and mineralogical data. Conversely, the molecular distribution of n-alkanes as reliable climatic and δ-MTTC as paleosalinity indicators do not support this conclusion.

AB  - The influence of geochemical processes (weathering, erosion and dilution) of the Internal Dinarides to the Posavina Neogene Basin and their implication to the pollution of the Sava River sediments at four sampling sites in the Eastern Posavina (Zupanja, Brcko, Bosanska Raca and Sremska Mitrovica) was studied.(similar to)For this purpose, comparison of contents of heavy metals (Pb, Zn, Cu, Ni, Cr, Cd, As and Hg) of the Eastern Posavina sediments with local background values was performed. Sediments from two boreholes of the Lopare Basin considered as non-polluted and representative for specific geologic and hydrogeologic system were used for the calculation of local background values. The aim was to assess whether the observed heavy metals concentrations at four sampling sites along the Sava River represent background/natural or anthropogenic contamination. This task was performed using the geo-accumulation index and total enrichment factor. According to values of the total enrichment factor (0.25-0.71), the anthropogenic impact on the investigated area was quite low. The heavy metals contents in river sediments, soil and groundwater were mainly controlled by geochemical processes, particularly weathering (chemical proxy of alteration value approximate to 60). The results also offer novel insights into the elevated geogenic levels of Cr and Ni in the Eastern Posavina region.

AB  - Sedimentary rocks from the saline formation of the Lopare Basin were investigated. Sediments contain a moderate amount of immature to marginally mature algal organic matter deposited under slightly reducing to anoxic and slightly saline to hypersaline conditions. Almost all of the samples contain beta-carotane in a relatively high quantity, and in some, it represents the most abundant compound in the total distribution of hydrocarbons. The objective of the study was to determine the conditions that are favourable to precursors of beta-carotene and/or the preservation of the carotenoid hydrocarbon skeleton. Moreover, the dominant transformation pathways of beta-carotene under different redox and salinity conditions, which lead to the formation of aromatic carotenoids were defined. Based on the content of beta-carotane, the examined sedimentary rocks are divided into groups A, B and C. Group A does not contain or contains up to 1% of beta-carotane, group B contains between 1 and 5% of beta-carotane, while group C contains more than 5% of 13-carotane in the overall distribution of hydrocarbons. The organic matter (OM) of the sediments of group A is characterized by a higher contribution of prokaryotic precursor organisms, in comparison with the other samples. The OM was deposited in a slightly saline reductive environment, with an increased erosion activity. This environment was unfavourable for the precursors of beta-carotene and/or for preservation of its hydrocarbon skeleton. Evidence for the degradation of the poliene chain in beta-carotene is the domination of monoaromatic compounds in the aromatic carotenoids distribution. The OM of sediments of groups B and C is similar, predominantly of algal origin deposited in a reducing to anoxic calm carbonate environment with salinity changes from hypersaline to saline. Such reduced to anoxic saline, but not hypersaline environments are most appropriate for precursors of beta-carotene and for the preservation of carotenoid skeleton. Cyclization and aromatization of polyene isoprenoid chain, whereby terminal groups remain the main pattern, is the main pathway of beta-carotene aromatization in anoxic hypersaline environments, whereas aromatization of terminal 1,1,5-trimethylcyclohexen-5-enyl groups and expulsion of toluene and m-xylene are typical for the reduced to anoxic saline environments.

environment, during the period of its creation. In addition, the aim of this study was to
determine which biomarkers and biomarker parameters are most sensitive to changes in
sedimentation environment. The potential impact from the investigative areas on the
environment, especially water and soil, was also investigated.
The qualitative composition of the mineral part of the sediment was determined
by X-ray diffractometer analysis (eng. X-Ray Diffraction, XRD), and the content of
macro-, trace- and rare earth elements by atomic emission spectrometry with inductively...",
