  • 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.

    Luka Jović (2024)
    Lamprofiri su grupa egzotičnih ultrakalijskih stena poznatih po sadrţaju nekompatibilnih elemenata i elemenata retkih zemalja. U našem delu sveta pojavljuju se u okviru ultrakalijskih provincija u Španiji, Italiji, Srbiji, Makedoniji i Turskoj. U Srbiji su zastupljeni ponajviše u zapadnim delovima zemlje, oko opština Ljubovija i Mali Zvornik, ali i u široj okolini Rudnika, Kopaonika i u istočnoj Srbiji. Mnoga ispitivanja sprovedena su u rudnom polju Veliki Majdan u zapadnoj Srbiji sa čije jugoistočne strane protiče Kolarička reka. Ovaj lokalitet ...

  • From DELA Based Dictionary to Leximirka Lexical Database

    Biljana Lazić, Mihailo Škorić (2020)
    In this paper, we will present an approach in transforming Serbian language Morphological dictionaries from a DELA text format to a lexical database dubbed Leximirka. Considering the benefits of storing data within a database when compared to storing them in textual documents, we will outline some of the functionality that the database has made possible. We will also show how hand-made rules that use category labels lexical entries are marked with can be used to link lexical entries. ...

  • Stratigraphic implications of the Mio-Pliocene geodynamics in the area of Mt. Avala: new evidence from Torlak Hill and Beli Potok (Belgrade, Serbia)

    Ljupko Rundić, Meri Ganić, Slobodan Knežević, Dejan Radivojević, Miloš Radonjić (2019)
    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. ...
