Composition of organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in East Herzegovina (External Dinarides, Bosnia and Herzegovina)
This paper presents the first data on the organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in the East Herzegovina region of the External Dinarides. Representative, organic-rich samples from outcropping sedimentary rocks of different ages in the area (Triassic to Neogene) were selected and analysed. The organic matter was studied by Rock-Eval pyrolysis and under the microscope in reflected non-polarized light and incident blue light. The results obtained show the presence of different types of organic ......

Contents of potentially toxic elements in residual soils of a long-term mining region: a key study from Central and Western Serbia
Milun Jovanović, Dejan Prelević, Vidojko Jović, Danica Srećković-Batoćanin, Snežana Branković (2022)Regional geochemical research of residual soil was conducted in an area of about 20,000 km2 in the region of Central and Western Serbia, where six metallogenetic zones and mining since ancient times have been documented. The geochemical background variation in the residual soil was established upon the contents, spatial pattern and natural background of potentially toxic elements (PTEs). The limits of natural background values (mg·kg-1) were determined by the integral method. Our data show that anomalous concentrations of As, ...Milun Jovanović, Dejan Prelević, Vidojko Jović, Danica Srećković-Batoćanin, Snežana Branković.

Estimating hydraulic parameters for the complex hydrodynamic models
Hydrodynamic models have usually been calibrated manually, by trial-and-error, with different values of hydraulic parameters and hydraulic characteristics of boundary conditions. This method of calibration and estimation of hydraulic parameters requires an extensive knowledge and experience of experts, but whether the resulting solution includes an optimal set of parameters still remains an open question. An optimization method founded upon the Gauss-Marquardt-Levenberg algorithm, along with PEST software based on that algorithm, introduces automation of model calibration with regularization, which substantially ...Dušan Polomčić, Dragoljub Bajić, Jelena Ratković, Bojan Hajdin.

Speleo‐morphology and tectonic processes – What can be seen in slowly deforming regions?
Ana Mladenović, Jelena Ćalić (2022)There are a lot of methods used to determine tectonic process active in a region, and they vary depending on the purpose of the research. However, a number of them cannot be used in slowly deforming regions, because the effects of active tectonic process on the rocks in such regions could be negligible. This is especially true for the recently active tectonics in such regions, since most of the recently active tectonic structures never reach the surface. Because of ...Ana Mladenović, Jelena Ćalić.

A contribution to the understanding of the discharge dynamics and water balance of the karst spring Gornji Dušnik (Suva Planina)
A sufficiently long time-series of daily discharges is needed to assess the discharge dynamics and calculate the water balance equation parameters of a spring (river source). The paper assumes that a catchment is gauged if a time-series of observations of at least 30 years is available, which is a rare case in Serbia. One-year monitoring is often set up to verify the reserves of a water source or spring intended for capture. Monitoring ceases after the final report is ...Aleksandar Tanasković, Vesna Ristić Vakanjac, Dušan Polomčić, Jelena Ratković.

Age And Mode of the Middle Miocene Marine Flooding of the Pannonian Basin—Constraints from Central Serbia
Oleg Mandic, Ljupko Rundić, Stjepan Ćorić, Ðurðica Pezelj, Dörte Theobalt, Karin Sant, Wout Krijgsman (2019)The timing and mode of the marine flooding of the southern margin of the Pannonian basin in SE Europe is still a matter of debate. In central Serbia, integrated bio-magnetostratigraphic data and quantified high-resolution records are completely missing. Here, we provide paleoenvironmental and paleoecological constraints from the Slanci section located near Belgrade that has an excellent preservation of micro-fauna and flora, i.e., planktonic and benthic foraminifera and calcareous nannoplankton.

Highway construction in fossil landslides zones – Lessons learned from the Grdelica Gorge, Serbia
Landslides are common on roads, which directly affect the flow of traffic and the connection and functioning of the population in surrounding area. Therefore, it is necessary to investigate them in the shortest possible time and to determine and carry out the remediation solution. Functionality of the state roads is immensely important so it is necessary to ensure that the traffic is maintained during remediation activities. Therefore, design solutions and remediation execution technology should be adapted to these requirements. ...Biljana Abolmasov, Marinos Skempas, Svetozar Milenković, Janko Radovanović, Miloš Marjanović.
