  • Петрологија црвених пешчара источне Србијe

    Андреј Марковић (2024)
    У источној Србији формација црвених пешчара има велико распрострањење и улази у састав многих планина овог дела наше земље. Формацију чине кластичне стене интензивно црвене боје псамитске, ређе псамитско-псефитске структуре и алевритске структуре. Ове стене леже трансгресивно преко старијих пермо-карбонских и карбонских стена, док навише прелазе у доњотријаске седименте. Формација црвених пешчара захвата два појаса унутар Карпато-балканида – унутрашњи и средишњи део. Узорци анализирани у овом раду део су средишњег појаса.

  • Upper Miocene depositional environments of the Kikinda-Mokrin High (Serbia)

    Saša Ivanišević, Dejan Radivojević (2018)
    Exploration for oil and gas in mature areas, such as the Pannonian Basin, can benefit from reexamination of old data using more advanced modern workflows that focus on the temporal and spatial aspects of sediment deposition. Specifically, we apply a new environment of deposition model that interprets the Upper Miocene- Pliocene sediments as being deposited in a rapidly filling basin characterized by quick shelf edge progradation from the northwest toward the southeast. Reconstruction of this shelf edge trajectory reveals ...

    Jovana Opančina (2024)
    Predmet ispitivanja ovog završnog rada su granatski amfiboliti Bistrice. Izvršena su petrografska i hemijska ispitivanja s ciljem da se odredi stepen metamorfizma, protolit ispitivanih stena i P-T uslovi nastanka. Ispitivani granatski amfiboliti geografski pripadaju Prijepolju, tačnije nalaze se na ulasku u Prijepolje, mesto Bistrica. Geološka građa obuhvata uglavnom mezozojske tvorevine među kojima se nalaze sedimentne, magmatske i metamorfne stene. Geološki procesi koji su doveli do stvaranja amfibolita su procesi subdukcije i obdukcije koji su se pretpostavljamo dešavali na većim ...

  • Uporedna analiza stabilnosti završnih kosina površinskog kopa „Veliki Krivelj“

    Mihajlo Topalović (2023)
    Površinski kop „Veliki Krivelj“ nalazi se u blizina grada Bora i u neposrednoj blizini sela Krivelj. Od 2018. godine je u vlasništvu kineske kompanije „Zijin“ koja ima udeo od 63% vlasništva celokupnog RTB-a Bor. Na površinskom kopu obavlja se masovna eksploatacija rude bakra opremom visokog kapaciteta. Za bušenje se koriste bušilice prečnika od 250 do 310 mm, a za utovar minirane rude i jalovine bageri čija je zapremina kašike 15 m3 i 22 m3. Za površinski kop „Veliki Krivelj“ ...

  • Testing the energy value of different types of coal by the method of active thermography

    Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Predrag Jovančić, Dragutin Jovković (2020)
    In this paper, coal thermograms are presented and analyzed in order to determine their energy value. Two types of coal of different categories, brown and lignite, were selected for active thermographic imaging. The tested coal samples were processed before measurement so that they are similar in dimensions and have two plane-parallel smooth surfaces. The test samples were "primarily" heated under the same conditions and the process of their cooling was monitored by a thermal camera. "Then" they were cooled ...

  • Clockwise vertical-axis rotation in the West Vardar zone of Serbia: Tectonic implications

    Vesna Lesić, Emo Márton, Violeta Gajić, Dragana Jovanović, Vesna Cvetkov (2018)
    The Vardar-Tethyan mega-suture between the Eurasian and Adria (Gondwana) margins comprises remnants of oceanic lithosphere of Neotethys and distal parts of the adjacent continental margins including unconformable Late Cretaceous sedimentary cover and Cenozoic igneous rocks of post-obduction age. This study provides kinematic constraints for displacements and rotations affecting the Serbian part of the West Vardar and Jadar-Kopaonik units after the closure of the Neotethyan (= Sava) Ocean. The targets of the paleomagnetic research were Late Cretaceous sediments representing an ...

  • Machine learning based landslide assessment of the Belgrade metropolitan area: Pixel resolution effects and a cross-scaling concept

    Uroš Đurić, Miloš Marjanović, Zoran Radić, Biljana Abolmasov (2019)
    Improvements of Machine Learning-based landslide prediction models can be made by optimizing scale, customizing training samples to provide sets with the best examples, feature selection, etc. Herein, a novel approach, named Cross-Scaling, is proposed that includes the mixing of training and testing set resolutions. Hypothetically, training on a coarser resolution dataset and testing the model on a finer resolution should help the algorithm to better generalize ambiguous examples of landslide classes and yield fewer over/underestimations in the model. This ...

    We present an in-depth landslide map of the ‘Umka’ landslide near Belgrade, Serbia, at a scale of 1:5000. The map delineates elements at risk, primarily buildings and road infrastructure impacted by the landslide displacements of several cm per year, introduced during frequent reactivation stages. The Main map results from a survey of over 350 buildings and more than 7 km of state and local roads. The acquisition techniques included engineering geological field mapping, building survey, and visual interpretation of ...
