  • U-Pb zircon geochronology of the Paleogene – Neogene volcanism in the NW Anatolia: Its implications for the Late Mesozoic-Cenozoic geodynamic evolution of the Aegean

    E. Yalçın Ersoy, Cüneyt Akal, Ş. Can Genç, Osman Candan, Martin R. Palmer, Dejan Prelević, İbrahim Uysal, Regina Mertz-Kraus (2017)
    The northern Aegean region was shaped by subduction, obduction, collision, and post-collisional extension processes. Two areas in this region, the Rhodope-Thrace-Biga Peninsula to the west and Armutlu-Almacık-Nallıhan (the Central Sakarya) to the east, are characterized by extensive Eocene to Miocene post-collisional magmatic associations. We suggest that comparison of the Cenozoic magmatic events of these two regions may provide insights into the Late Mesozoic to Cenozoic tectonic evolution of the Aegean. With this aim, we present an improved Cenozoic stratigraphy ...

  • Utilizing sewage wastewater heat in district heating systems in Serbia: effects on sustainability

    Marija Živković, Dejan Ivezić (2021)
    Transformation of the heating sector is recognized as being essential for ensuring reliable and afordable energy services provided with reduced consumption of energy sources and diminished impact on the environment and less import dependency. The possibility of utilizing energy sources that otherwise would be wasted needs to be considered and treated as a big advantage of district heating systems. Despite many advantages, sewage wastewater heat is still a mostly unused resource at the global level and a totally unused ...

  • Remedijacija otpadnih voda Rudnika prirodnim zeolitom

    Igor Veličković (2024)
    U radu je razmatrano prečišćavanje otpadnih flotacijskih voda sa područja rudnika Rudnik prirodnim zeolitskim tufom sa planine Jastrebac. Prečišćavanje otpadnih flotacijskih voda sa područja rudnika Rudnik prirodnim zeoliskim tufom sa obronaka planine Jastrebac pokazala se veoma efikasnom. Naime, u tri otpadne flotacijske vode utvrđen je povišen sadržaj arsena, hroma, gvožđa, mangana, kao i nikla. Jednostavnim tretmanom zeolitskim tufom iz ovih voda uklonjeni su svi ovi elementi. Sadržaji gvožđe i mangana su sniženi od 95 do 99 %, dok su ...

  • Mafic alkaline metasomatism in the lithosphere underneath East Serbia: Evidence from the study of xenoliths and the host alkali basalts

    Cvetković Vladica, Downes Hilary, Höck Volker, Prelević Dejan, Lazarov Marina (2010)
    Effects of mafic alkaline metasomatism have been investigated by a combined study of the East Serbian mantle xenoliths and their host alkaline rocks. Fertile xenoliths and tiny mineral assemblages found in depleted xenoliths have been investigated. Fertile lithologies are represented by clinopyroxene (cpx)-rich lherzolite and spinel (sp)-rich olivine websterite containing Ti–Al-rich Cr-augite, Fe-rich olivine, Fe–Al-rich orthopyroxene and Al-rich spinel. Depleted xenoliths, which are the predominant lithology in the suite of East Serbian xenoliths, are harzburgite, cpx-poor lherzolite and rare ...

  • Possibilities of retro-digitalized German-Serbian Mining Dictionary

    Biljana Lazić, Olivera Kitanović, Ivan Obradović (2019)
    U radu će biti prikazan opis procesa retrodigitalizacije dvojezičnog Nemačko-srpskog rudarskog rečnika iz 1923. godine čiji je autor rudarski inženjer Dragutin Stepanović (Степановић, 1923). Ovaj rečnik je zasnovan na skoro 4 000 leksičkih zapisa koji su prevodilački ekvivalenti ili uputnice. Umesto predgovora autor daje uvid u svoje pismo upućeno “Ministru šuma i rudnika” u kome piše o nameri da zabeleži reči koje se koriste u narodu kako bi izbegao upotrebu nemačkih reči. Iako broj odrednica nije toliko veliki, rečnik ...

  • Geochemical evaluation of dolostone deposits in Montenegro: Implications for potential industrial applications

    Darko Bozovic, Vladimir Simic, Dragan Radulovic, Slobodan Radusinovic, Vesna Matovic, Anja Terzic (2024)
    This study presents a unique model for assessing the dependability of continuous parts of combined systems in open-pit mining through the application of fuzzy logic. Continuous sub-systems as part of the combined system of coal exploitation in surface mines have the basic function of ensuring safe operation, high capacity with high reliability, and low costs. These subsystems are usually part of the thermal power plant’s coal supply system and ensure stable fuel supply. The model integrates various independent partial ...

  • Synergy between the mineral deposit exploration and geothermal resources assessment on the example of "Valjevo" boron and lithium deposit in Serbia

    Nebojša Atanacković, Vladimir Živanović, Ana Vranješ, Sava Magazinović, Marinko Toljić, Ana Arifović, Branislav Potić (2023)
    Exploration of mineral deposits involves a collection of vast data sets on geological characteristics of the area. These data can largely contribute to the assessment of the geothermal potential, which can lead to an increase in the share of geothermal resources in the energy mix of the extractive industry and the local community. On the example of the "Valjevo" B-Li deposit, data on structural settings and previous hydrogeological investigations were combined with the results of resource drilling and geophysical ...

  • Chemo-probe into the mantle origin of the NW Anatolia Eocene to Miocene volcanic rocks: Implications for the role of, crustal accretion, subduction, slab roll-back and slab break-off processes in genesis of post-collisional magmatism

    E. Yalçın Ersoy, Martin R. Palmer, Ş. Can Genç, Dejan Prelević, Cüneyt Akal, İbrahim Uysal (2017)
    Post-collisional Cenozoic magmatic activity in NW Anatolia produced widespread volcanism across the region. In the Biga Peninsula, in the west, medium-K calc-alkaline to ultra-K rocks with orogenic geochemical signature were emplaced at ~43–15 Ma (Biga orogenic volcanic rocks; BOVR). Volcanic activity in the Central Sakarya region, to the east, is mainly restricted to ~53–38Ma, but also continued during the Early Miocene with small basaltic extrusives (Sakarya orogenic volcanic rocks; SOVR). This study presents a new set of geochemical data ...

  • Multi-word Expressions for Abusive Speech Detection in Serbian

Posebnu pažnju posvećujemo dodavanju izraza sa više reči (polileksemskih jedinica) koji se mogu smatrati uvredljivim, jer su takvi leksički zapisi veoma važni za postizanje dobrih rezultata u mnoštvu zadataka otkrivanja uvredljivog jezika. Srpski morfološki rečnici se koriste kao osnova za čišćenje podataka i stvaranje rečnika.

  • Knowledge and Rule-Based Diacritic Restoration in Serbian

    Cvetana Krstev, Ranka Stanković, Duško Vitas (2018)
    In this paper we present a procedure for the restoration of diacritics in Serbian texts written using the degraded Latin alphabet. The procedure relies on the comprehensive lexical resources for Serbian: the morphological electronic dictionaries, the Corpus of Contemporary Serbian and local grammars. Dictionaries are used to identify possible candidates for the restoration, while the dataobtainedfromSrpKorandlocalgrammarsassistsinmakingadecisionbetween several candidates in cases of ambiguity. The evaluation results reveal that,dependingonthetext,accuracyrangesfrom95.03%to99.36%,whilethe precision (average 98.93%) is always higher than the recall (average 94.94%).

  • The Late Devonian contraction along the Precaspian Basin north margin: Transpressional range building in the intracratonic domain

    Novak Novčić, Marinko Toljić (2023)
    The evolution of intraplate sedimentary basins located in the vicinity of an active convergent plate boundary is often controlled by the collisional dynamics of the adjacent orogen. The transfer of compression from the orogen to the platform's interior results in the formation of complex structural geometry and kinematics that often reactivate older crustal faults, focus far-field stresses and control the evolution of associated sedimentary basins. One place where this localisation can be optimally understood is the Precaspian Basin, situated ...
