  • Lamprofiri Kolaričke reke (Boranja)

    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 ...

  • Anisotropic grossular–andradite garnets: Evidence of two stage skarn evolution from Rudnik, Central Serbia

    Bojan Kostić, Danica Srećković-Batoćanin, Petyo Filipov, Pavle Tančić, Kristijan Sokol (2021)
    This paper presents LA-ICP-MS data for garnets from the Rudnik skarn deposit (Serbia), which range from Grs45–58Adr40–52Alm2–3 in the core and Adr70–97Grs2–29Sps1 in the rim displaying anisotropy and zoning. In spite of wide compositional variations the garnets near the end-member of andradite (Adr > 90) are generally isotropic. Fe-rich rims exhibit LREE depletion and flat HREE pattern with weak negative Eu anomaly, including higher As and W contents. On the other side, the Fe-poorer core shows flat REE pattern ...

  • 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.

  • 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 ...

  • Prostorni položaj ofiolita istočne Vardarske zone: geofizičko-geološki model i njegove geodinamičke implikacije

    Dragana D. Petrović (2015-12-29)
    Centralni deo Balkanskog poluostrva je geotektonski veoma složen. Tetis je zatvorentokom gornjeg mezozoika, a ofioliti na zapadu i ofioliti Vardarske zone predstavljajuostatke nekadašnjih okeanskih prostora. Najistočniji deo Vardarske zone razlikuje se odsvih ostalih ofiolita na Balkanskom poluostrvu i karakteriše se najizraženijim suprasubdukcijskimafinitetom. Istočna vardarska zona locirana je u centralom delu Srbije.Na severu se prostire do Apusena u Rumuniji, a na jugu obuhvata cetralni deoMakedonije i Peonias zonu u severnoj Grčkoj. Istočna vardarska zona se nalazi istočnood geotektonske jedinice Kopaonik ...

    Proučavan je efekat „zatrpanog kamena“ na intenzitet procesa degradacije prisutnih na kersantitu koji je ugrađen u spomenik Malo stepenište. Istraživanja su vršena na uzorcima stene iz kamenoloma i na oštećenim kamenim blokovima ugrađenim u spomenik. Dok su neki delovi stepeništa bili pod zemljom 90 godina, većina kamenih elemenata je bila izložena različitim uslovima sredine i antropogenim uticajima. Urađeno je detaljno mapiranje trenutnog stanja spomenika kako bi se istražio uticaj “zatrpavanja” i kompleksne geometrije spomenika na tip propadanja i variranje ...

  • Late and post-collisional tectonic evolution of the Adria-Europe suture in the Vardar Zone

    Emő Márton, Marinko Toljić, Vesna Cvetkov (2022)
    The Vardar Zone is a product of the Triassic-Jurassic opening of the Neotethys, Jurassic obduction, Late Cretaceous/Paleogene consumption of the oceanic crust and continental collision. During the last process, the Eastern Vardar Zone was thrust over the Central and eventually both onto the Western Vardar Zone. The present paleomagnetic and structural study provided new results from the first two zones in the Belgrade area. The younger set of data, together with published ones from the third zone, provide firm ...
