Five celestine crystals are sampled from the (paleo)surface intervening between the late Miocene to Pleistocene basaltic sequences of the Jabal Eghei(Nuqay) volcanic province (southern Libya). The celestine specimens are characterized by applying the combination of the SEM-WDS, ICP/OES, XRPD, and IR methods. The celestine minerals are further analy...

Five celestine crystals, sampled from the surface at the Miocene to Pliocene Jabal Eghei (Nuqay) volcanic province (southern Libya), are characterized by applying the combination of the SEM-WDS, XRPD and IR methods; and analyzed for their color variations and minerogenesis. Three samples have greenish-blue to blue (480.4−482.5 nm), whereas the othe...

A microtectonic study was conducted in the Levac region of central Serbia. Here, the tectonic contacts between the Europe?derived units, including the Serbo-Macedonian unit and Jurassic sedimentary cover of the European margin, and the Eastern Vardar Ophiolitic unit, are exposed at the surface. The results indicate that the contact zone underwent a...

Machine learning has been gaining acceptance as an industry-wide used tool for analyzing whole rock and mineral chemistry data during the last decade (e.g., Ahmed et al., 2020, Dmitrijeva et al., 2022), with the range of applications from classifying rock types and alteration styles to vectoring during mineralization prospecting. We have obtained g...

The Bor deposit is a world-class porphyry-high sulfidation system located in eastern Serbia. It has been mined since the very beginnings of the 20th century. Veliki Krivelj is a porphyry type Cu-Au deposit, currently mined by open-pit, located around 4 km north of Bor mine. Čukaru Peki is a recently discovered porphyry and high-sulfidation type Cu-...

The Rudnik Mts, Serbia, is a volcano-intrusive complex and is located on the suture between passive Adria and active Europa margin zone. This northwest-southeast elongated area is composed mostly of the Albian- Cenomanian laminated clastics and carbonates in a proximal shelf environment and Cenozoic volcanics, as well. The sediments are metamorphos...

This study focuses on the mineralogical characterization of bentonite clay from Svrljig, Serbia. It has been found that bentonite clay is the most abundant clay in this region, therefore an adequate identification of their mineralogy and physicochemical properties is an important step to a potential technical application in the future. Characterist...

The Vršac Mts. in NE Serbia represent the key area to investigate structural relations between the Northern Serbo-Macedonian Subunit and Supragetic Unit of the Dacia Mega-Unit. The geodynamic events during the Variscan orogeny in the Late Paleozoic colligated the two units and led to their metamorphic differentiation. The Late Cretaceous extension...

Inclusions in garnets from the river Lešnica alluvion (Cer mountain area, Serbia), were investigated in an effort to study their distribution within the garnet host and to estimate the mechanism of their origin. Garnets are often occurring in the Lešnica alluvion in a form of loosely separated crystals with preserved crystalline forms and as mildly...

This paper presents LA-ICP-MS data for garnets from the Rudnik skarn deposit (Serbia), which range from Grs 45-58 Adr 40-52 Alm 2-3 in the core and Adr 70-97 Grs 2-29 Sps 1 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 r...

Loess is a highly porous and easily erosive aeolian sediment covering approximately 10% of the Earth’s surface. The weak vegetation cover and high wind speeds in many of these regions make loess sediment the main source of dust in the atmosphere. Dust particles deteriorate air quality and affect soils, crops, water systems, and animal and human hea...

Lower-Middle Miocene sedimentary succession and the conformable/ unconformable relationships between the lacustrine-continental systems (i.e. DLS, SLS) and Badenian marine transgression represents one of the intrigue topics. Herein, we studied five exploration boreholes (eastern Serbia) and analyzed the main facies pattern, biostratigraphic charact...

Late Cretaceous global plate reorganization associated with the inception of counterclockwise rotation of Africa relative to Europe initiated in the Balkan region small-volume magmatism of diverse geochemical signature along the enigmatic Sava-Vardar Zone. We study a Late Cretaceous lamprophyric sill in Ripanj village near Belgrade to constrain thi...

The occurrence of minerals from the garnet group in the alluvion of Lešnica river (Cer) and their mineralogical characterization have not been investigated in detail and have been reported in this paper. Granulometry methods, spectrophotometry, infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) and SEM-EDS method have been applied on previously...

The polymetallic Bobija ore deposit in Western Serbia is located at the southwestern edge of the Jadar Block, a distal part of the passive continental margin of Adria. The sulphide mineralization consists of fine-grained pyrite, sphalerite, galena and tetrahedrite, and is associated with abundant barite. The deposit is stratabound and hosted by a T...

The study reports and discusses new LA–ICP–MS zircon U–Pb data and major and trace element analyses for 16 samples from nine different plutons intruding the Getic (Brnjica, Neresnica, Ziman, Gornjane–Tanda–Blizna), and the Danubian (Aldinac, Janja, Ravno Bučje, Plavna and Suvodol) units of the East Serbian Carpatho-Balkanides (ESCB). Within the ent...

Mg-Al hydrotalcites (Mg/Al molar ratio 3/1) doped with varying amounts of lanthanum were prepared using co-precipitation followed by calcination in order to study the effect of lanthanum on their structure and morphology. Samples were characterized by several methods: XRD, FT-IR, SEM-EDS, LDPSA and MIP. It was found that the addition of lanthanum a...

Magnetic polymer microspheres consisting of a polymer and inorganic magnetic nanoparticles have been successfully used for separation of toxic and radioactive pollutants [1]. Bentonite as well has been proved as an excellent adsorbent for heavy metals and organic pollutants removal from wastewaters [2]. In order to combine favorable characteristics...

Fault-related folds and hanging-wall structures reflect the geometry of the main thrusts in foldthrust belts. The results of the structural analysis of the Supragetic Unit metamorphic basement in eastern Serbia at map-, outcrop- and thin-section scale, and its importance for the late Early Cretaceous nappe-stacking are presented in this paper. The...

Eight relatively large masses and few small occurrences of Hercynian granitoids intrude metamorphic complexes of Late Proterozoic to Early Cambrian terranes of the East Serbian Carpatho-Balkanides. These granitoids are still poorly investigated. The results of geothermobarometric calculations for the granitoids of Ziman, Tanda, Radičevac, Janja, Su...

In the territory of central Šumadija (Ostenjak near Aranđelovac),“dyes stone” - as the locals named it originally - has been exploited until the 1990’s and used in the paint and dye industry. The lack of analytical data on the rocks from this occurrence makes this locality interesting for further research. In this study we present new field observa...

River sediments are a major source of metal contamination in aquatic food webs. Due to the ability of metals to move up the food chain, fishes, occupying higher trophic levels, are considered to be good environmental indicators of metal pollution. The aim of this study was to analyze the metal content in tissues of the common barbel (Barbus barbus)...

Biocrusts and adjacent sediments were collected from the so-called loess plateau of Northern Iran and the loess deposits on the foothills of Alborz Mountains. The mineralogical and granulometric analyses characterized sediments as quartz-rich clayey or sandy silts. Cyanobacterial diversity, colony morphology and grain stabilization were studied by...
