Pavle I. Tančić (2016-09-21)U ovoj Doktorskoj disertaciji proučavano je pet različitih zona makroskopski zonarnog grandita sa lokaliteta Meka Presedla (Kopaonik, Srbija). Pomoću hemijske i elektronske analize mikroprobe preračunati su relativno visoko homogeni sastavi zona, t.j.: Grs64±1Adr36±1Sps2 (A), Grs62±1Adr38±1Sps2 (B), Grs59±2Adr40±2Sps2 (C), Grs58±2Adr41±2Sps2 (D) i Grs58±1Adr41±1Sps2 (E).

Anisotropic grossular–andradite garnets: Evidence of two stage skarn evolution from Rudnik, Central Serbia
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 ...... southeastern Alaska. The Canadian Mineralo gist 34, 1195–1209.

Structural dissymmetrization of optically anisotropic Grs64±1Adr36±1Sps2 grandite from Meka Presedla (Kopaonik Mt., Serbia)
In this paper, grandite core with Grs64±1Adr36±1Sps2composition was crystallographically studied. This core represents zone A of the macroscopically visiblefive A–E zones of the optically anisotropic Grs58–64 Adr36–42Sps2 grandite. The applied procedure includes the detailed analysis of the powder diffraction patterns, and the Rietveld refinements of the crystal structures in a series of 18 space groups and two mixtures, which were followed by the comparative analysis of the R-values, site occupancy factors, and the bond lengths and angles.

Uticaj površinske obrade kamena na promenu primarne poroznosti
Ana Radivojević (2024)Površinska obrada kamena je izuzetno bitna kod stena koje se koriste u izgradnji svih vrsta objekata. Površinskom obradom se direktno utiče, ne samo na estetska svojstva kamena nego i na njegove fizičko-mehaničke karakteristike. Cilj ovog završnog rada je analiza uticaja poliranja i rezanja kao tehnoloških procesa obrade na poroznost odabranih vrsta arhitektonsko-građevinskog kamena. Ispitivane stene su gabro „Nero Assoluto“, granit sa površinskog kopa „Ploče“, granit African Red, krečnjak sa lokaliteta „Skržut“ i krečnjak poznat pod nazivom „Sirogojno crveni“.... granites of the Bushveld Complex.

Agates of the Lece Volcanic Complex (Serbia): Mineralogical and Geochemical Characteristics
Agate veins and nodules occur in the Lece Volcanic Complex (Oligocene-Miocene) situated in the south of Serbia and occupying an area of 700 km2. This volcanic complex is composed predominantly of andesites, with sporadic occurrences of andesite-basalts, dacites and latites, and features agate formations that have been very little investigated. This study focuses on five selected agate occurrences within the Lece Volcanic Complex, employing optical microscopy, scanning electron microscopy (SEM), X-ray powder diffraction analysis, inductively coupled plasma mass spectrometry ...Zoran Miladinović, Vladimir Simić, Nenad Nikolić, Nataša Jović Orsini, Milena Rosić.

Arsenopirit iz rudnih ležišta Šumadijsko-kopaoničke oblasti: paregeneza, sastav i produkti oksidacije
Ivana N. Jelić (2023)Arsenopirit, FeAsS je čest pratilac polimetaličnih orudnjenja Šumadijsko-kopaoničke oblasti. Jedan je od sulfida koji u najvećoj meri koncentriše zlato. Nepoželjan je u rudama jer njegovom oksidacijom na jalovištima može doći do oslobađanja arsena koji spada u elemente toksične za životnu sredinu. U okviru ovog doktorata sistematski su ispitivani arsenopiriti iz različitih stadijuma i tipova orudnjenja rudnih ležišta i mineralizacija Šumadijsko-kopaoničke oblasti (Rudnik, Sastavci, Trepča, Gokčanica – Drenjak i Rujak, Golijska reka i Jurija).
