    Nikola Otašević (2024)
    U ovom radu predstavljene su osnovne geološke karakteristike šireg područja Grivske. U litostratigrafskom pogledu na ovom prostoru prisutne su paleozojske, mezozojske i kenozojske sedimentne, magmatske i metamorfne stene. Tvorevine karbona su predstavljene semimeta-morfisanim tvorevinama.Tvorevine trijaske starosti su predstavljene slojevitim i masivnim krečnjacima, dok su tvorevine jure predstavljeni produktima ofiolitskog melanža. Takođe, prisutne su i tvorevine senona koje su predstavljene masivnim krečnjacima. U neogenoj sukcesiji dominiraju klastiti miocena, dok su u kvartaru zastupljeni različiti tipovi fluvijalnih, deluvijalnih i deluvijalno-proluvijalnih tvorevina. ...

  • Correlation Between Dynamic CBR and Compaction and Bearing Capacity of Pavement Foundation Layers

    Milan Bogdanović, Snežana Bogdanović, Dragoslav Rakić, Irena Basarić Ikodinović (2024)
    This paper presents a dynamic California Bearing Ratio (CBRd) device that can be used on a prepared pavement foundation layer to obtain a certain parameter of the tested material in the laboratory and in situ in a direct and fast way. For the selected natural material (gravel), it is shown that the laboratory CBRd can be used to estimate the compaction and bearing capacity, because it correlates well with the parameters of the standard and modifed Proctor compaction tests. ...

  • Geotechnical Conditions for Construction of Savski Trg Metro Station as a Part of the Belgrade Metro Line One

    Nemanja Stanic, Dragoslav Rakic, Josip Isek, Slavoljub Simic (2024)
    In order to solve serious traffic congestion in Belgrade, a number of studies regarding the Belgrade Metro construction have been carried out since 1973. However, only in 2019, the routes of the future metro lines 1 and 2 were de-fined as a part of the General Metro Construction Project. The lines are de-signed to intersect at the location of Sava Square, where an interchange met-ro station will be built. It represents a complex geotechnical structure consist-ing of three different ...

  • Micro- to nanoscale textures of gold in arsenopyrite and scorodite from the As-Au-Bi assemblage of Drenjak locality (Serbia)

    Ivana Jelić, Janez Zavašnik, Marina Lazarov, Alena Zdravković, Sabina Kovač, Jovica Stojanović, Aleksandar Pačevski (2023)
    Arsenopyrite and pyrite are important carriers of Au that is present in the form of microscopic and “invisible” gold. Such gold can be expected to be released upon the process of oxidation of these sulfides. In studied gold mineralization at Drenjak, related to the granitoids of the Oligocene-Miocene Kopaonik Ore District, the main arsenopyrite-pyrite-(bismuthinite) sulfide assemblage was formed in the quartz bodies and partly replaced by scorodite (FeAsO4·2H2O) and Bi-arsenate. With only up to 5 ppm of gold recorded ...

  • Molecular and Isotope Composition of Biomarkers in Immature Oil Shale and its Liquid Pyrolysis Products (Open and Closed System)

    Gordana Gajica, Aleksandra Šajnovic, Jan Schwarzbauer, Aleksandar Kostić, Branimir Jovančićević, Ksenija Stojanović (2021)
    The molecular and isotopic composition of biomarkers in initial bitumen isolated from raw immature oil shale samples from the Lower Miocene Aleksinac Basin (Serbia) and liquid products (LPs) obtained by pyrolysis in open (OS) and closed systems (CS) are studied. The influence of pyrolysis type and variations of kerogen type on biomarkers composition and their isotopic signatures in LPs is determined. The molecular composition of the LPs from the OS pyrolysis is very similar to those in initial bitumen, independently ...

    geochemical and mineralogical study was performed on lignite samples from the Upper Miocene Kovin deposit, hosting three coal seams. 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). ...

    Snežana M. ignjatović, Ivana M. Vasiljević, Nevena R. Andrić-Tomašević, Ana S. Mladenović (2024)
    Bihaćki i Cazinski baseni su neogeni baseni, koji pripadaju spoljašnjim Dinaridima i formirani su tokom kasne faze razvoja Dinarida. Ovi baseni su od posebnog interesa zbog svoje geološke prošlosti i potencijalnih strukturnih karakteristika. U istraživanju, primenjeni su gravimetrijski podaci u clju boljeg razumevanja evolucije ovih basena. Primenom različitih postupaka matematičkih transformacija na gravimetrijskim podacima može se ustanoviti gravitacioni uticaj neogenih basena male gustine i mogu se detektovati strukture, koje su potencijalno vezane za njihovo formiranje.

  • Stepen metamorfizma metaklastita rudnika

    Vanja Ćuk (2024)
    Zadatak ovog rada je bio, potvrda saznanja da se na planini Rudnik dogodio kontaktni metamorfizam gornjokrednih sedimentnih stena i da se ispita intenzitet kontakto-metamorfnih promena. Posle kraćeg opisa geografskog položaja, pregleda ranijih istraživanja i geologije šireg područja, usmerena je pažnja na petrološka ispitivanja metaklastita i na kontaktno-metamorfne facije. Usled stvaranja različitih vulkanogenih facija odnosno usled vulkanskih erupcija, delovanjem zagrejane magme (lave) ili zagrejanih fluida, došlo je do kontaktnog metamorfizma, na granici oligocen-miocen i do stvaranja različitih metamorfnih stena, a ...

  • Mikroelementi u kvartarnim sedimentima i lignitu Kostolačko-kovinskog ugljonosnog basena, istočna Srbija – odabrani primeri

    Bogoljub Vučković, Biljana Radovanović, Dragana Životić (2022)
    Sadržaj, distribucija i način pojavljivanja elemenata u tragovima (mikroelemenata), posebno potencijalno toksičnih i radioaktivnih elemenata u uglju, su od velikog značaja, posebno ako se koriste kao gorivo u termoelektranama (TE). Na osnovu sistematski prikupljenih podataka o elementima u tragovima u uglju, zemljištu i sedimentima, moguće je utvrditi stepen zagađenosti vazduha, zemljišta, vode, kao i negativan uticaj na zdravlje ljudi. Eksploatacija i istraživanje lignita u Kostolcu i Kovinu traje više od jednog veka, dok se sagorevanje lignita sa površinskih kopa ...

    U ovom radu analizirani su kvartarni klastiti iz bušotine kod Aranđelovca IB 18-3, sa ciljem boljeg razumevanja njihovih sedimentoloških i litoloških karakteristika. Kvartarni sedimenti su prilično homogenog/uniformisanog sastava i čine ih finozrni klastiti (dominantno alevroliti) sa određenim procentom peskovite i glinovite frakcije. Oni su iskartirani u samoj povlati i debljina im je 27 m. U podini su gornjokredne karbonatne stene (krečnjaci, laporci, rekristalisali/mermerisani karbonati) i miocenski sediment predstavljeni raznovrsnim varijetetima klastično karbonatnih stena.

  • Pleistocene rhinoceros from Bogovina Cave: the first report of Stephanorhinus hundsheimensis Toula, 1902 (Mammalia, Rhinocerotidae) from Serbia

    Predrag Radović, Miloš Radonjić, Emmanuel Billia (2020)
    Finds of Pleistocene rhinoceros are rare in Serbia, and only one species (the woolly rhinoceros Coelodonta antiquitatis Blumenbach, 1799) has been reported so far. The current paper presents the dental material of an extinct so-called Hundsheim rhinoceros, Stephanorhinus hundsheimensis Toula, 1902 from Bogovina Cave (East ern Serbia). Both the morphological and metric characteristics of the teeth are consis tent with the attribution to S. hundsheimensis. Unfortunately, the rhinoceros material originated from an uncertain geological context, so there is no ...
