Paleovegetation and environment during deposition of the Late Oligocene sub-bituminous coal in the Bobov Dol Basin (SW Bulgaria) as deduced from petrographic and geochemical characteristics
Alexander Zdravkov, Achim Bechtel, Doris Groβ, Ivan Kojić, Ksenija Stojanović, Dragana Životić (2024)Coal and carbonaceous shale samples were taken from the Late Oligocene Bobov Dol Basin, SW Bulgaria. Seams Ia, I, IIa+b, III, IV and V from the coal-bearing Bobov Dol Fm. were sampled to provide insights into the peat forming vegetation and depositional environment based on detailed organic petrological and geochemical study. The petrographic composition indicates that both coals and carbonaceous shales contain predominantly terrestrial organic matter with abundant huminite macerals and locally enriched liptinite macerals. Inertinite is rare or ...Alexander Zdravkov, Achim Bechtel, Doris Groβ, Ivan Kojić, Ksenija Stojanović, Dragana Životić.

Dragana Životić, Gligor Jovanovski, Vladimir Simić, Ivan Boev, Vesna Cvetkov, Petre Makreski, Dušan Polomčić, Vesna Ristić Vakanjac (2024)Coal exploration is a very demanding task, highly dependent on geological and economic factors and the utilization of coal. This lecture text includes information on a variety of geological techniques used in the exploration of coal and coal-bearing sequences, as well as on the calculation, assessment, classification, and reporting of coal resources and reserves. The main features of coal utilization and some environmental aspects are explained briefly. Special attention is paid to the by-products of coal utilization, their uses, ...угаљ, истраживање, ресурси, резерве, коришћење, сагоревање, карбонизација, гасификација, угљенични материјалиDragana Životić, Gligor Jovanovski, Vladimir Simić, Ivan Boev, Vesna Cvetkov, Petre Makreski, Dušan Polomčić, Vesna Ristić Vakanjac.

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). ...Dragana Životić, Olga Cvetković, Predrag Vulić, Ivan Gržetić, Vladimir Simić, Konstantin Ilijević, Biljana Dojčinović, Suzana Erić, Bogdan Radić, Sanja Stojadinović, Snežana Trifunović.
