The use of biological markers in determination of origin and type of organic matter in the Tisza river sediments
Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević (2013)The objective of the study was to determine the origin and type of organic matter (OM) of the Tisza recent sediments along the distance of 153 km through the territory of Serbia. For this purpose group organic-geochemical parameters and biomarker compositions were used. All samples contain approximately same amount of OM, which was deposited under uniform, slightly reducing conditions. Based on the distribution of n-alkanes, the origin and type of OM could not be precisely estimated. However, n-alkane patterns ...... Salih, Ö.

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 ...... organic car- bon – TOC, mg hydrocarbons/g rock, etc.), but also on thermal maturity (Peters and Cassa, 1994; Behar et al., 2001; Dembicki, 2017; Bechtel et al., 2018).

Therefore, the low CO2 emissions from the KBR xylitic lignite can also be explained biologically (Fig. 5a) ...

The Kovin lignite is characterized by high moisture content, medium to high ash yield, medium to high sulphur content and a relatively low gross and net calorific value. The mineralogical composition, and major and trace element contents were determined by X-ray diffraction, scanning electron microscopy with energy dispersive Xray spectroscopy (SEM-EDS) analyses, and inductively coupled plasma optical emission spectrometry (ICP-OES). ...... , ŽIVOTIĆ, D., BECHTEL, A., ŠAJNOVIĆ, A. & STOJANOVIĆ, K.

Properties of fly ash and slag from the power plants
This paper describes the physical, chemical and mineral properties of ash and slag, which were taken from thermal power plants Nikola Tesla A, Nikola Tesla B, Kostolac A and Kostolac B. The knowledge of the mineralogical material composition is important because the type of minerals directly determines the properties of the fly ash and slag and their possible application.

Geološke karakteristike neogenih sedimenta na prostoru šire okoline Ledinaca
Aleksandar Tričković (2024)Sagledavanje evolucije neogenih sedimenata na prostoru šire okoline sela Ledinci omogućeno je primenom različitih stratigrafskih metoda na površinskim i potpovršinskim podacima. Za izradu rada korišćene su sedimentološke, biostratigrafske, geofizičke i riftno sekvencione metode, koje su primenjene na površinskim izdancima i bušotinama. Primenom principa riftne sekvencione stratigrafije na podacima dobijenim geofizičkim karotažnim merenjima dobijeni su podaci o vremenu ekstenzije u Panonskom basenu. Pored toga ovi podaci zajedno sa sedimentološkim i stratigrafskim metodama omogućili su izdvajanje depozicionih sredina tokom neogena.

Stratigraphic implications of the Mio-Pliocene geodynamics in the area of Mt. Avala: new evidence from Torlak Hill and Beli Potok (Belgrade, Serbia)
Mt. Avala is located on the southern margin of the Pannonian basin (SPB), a border zone between the uplifted morphostructures of the Dinarides and Carpathian-Balkanides. Similar to the Pannonian basin, tectonostratigraphic evolution of the Mt. Avala area during the last 23 Ma has is characterized by syn- and post-rifting processes as well as tectonic inversion. Here, we present the results of field investigations of the Miocene‒Pliocene dynamics that led to different spatial positions of the same stratigraphic units (e.g. ...... 1st Congress of geologists of Bosnia & Herzegovina, Tuzla October 21–23, 2015, Book of Abstracts, 48–49.

The influence of pyrolysis type and variations of kerogen type on biomarkers composition and their isotopic signatures in liquid products is determined. The applicability of pyrolysis type, numerous biomarkers and carbon isotopic compositions (δ13C) of n-alkanes in liquid pyrolysates is established.
