Article
We provide new insights into the Badenian transgression (Langhian to early Serravallian) in western Serbia, focusing on the marginal part of the Central Paratethys. Nano- and microfossils (calcareous nannofossils, foraminifers, and ostracods) are used along with U–Pb radioisotope dating of a tuff layer near the Badenian lower boundary to reconstruc...
Article
Coal samples from the Jarando, Tadenje and Progorelica mines and organic-rich shale samples from the Piskanja boron deposit, all located in the Tertiary Ibar Basin, were studied using several methods such as transmitted light microscopy, X-ray powder diffraction (XRD), scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS)...

Badlands, often described as natural field laboratories, are landscapes of limited vegetation, with reduced or not existing human activity that are exposed to a wide range of geomorphological processes. These areas are made of mostly soft and poorly consolidated terrigenous, lacustrine or marine sediments of different age that were developed under...

Heavy metals as environmental pollutants can have natural or anthropogenic origin. To determine the river sediment pollution status, it is crucial to have appropriate reference samples, free of anthropogenic impact, and natural reference samples should be used wherever and whenever possible. The collection of reference samples should be performed i...

Tufa accumulations from the Gostilje River Basin and the Sopotnica River Basin in SW Serbia are represented by both active and fossil tufa precipitates. The aim of this study is to distinguish and describe different tufa facies and to determine the environmental conditions, based on stable isotope data. We also compare our analysis with other tufa...

Filling of dolines with aeolian sediments, one of the less frequently described ways in which they are filled, is analysed in the present study on an example of a doline in the high-mountain karst of the Dinarides. There is a series of deep dolines on a broad ridge (about 2450 m a.s.l.) on Mt. Durmitor (Montenegro) in the southeastern part of the D...

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...
Article
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 displac...

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...
Article

The succession of radiolarian assemblages in the Struganik section of western Serbia is described for the first time. The following radiolarian beds are defined in carbonate flyschoid sequences represented by thin-platy limestones with calcarenite and bentonite clay intercalations (from the base upward): Theocampe urna-Dictyomitra koslovae (presuma...

The field, petrological-mineralogical, geochemical and geochronological data of the metamorphic sole rocks recorded beneath the Fruška Gora, Povlen (Tejići), Stolovi and Banjska ophiolites in the Western Vardar Zone (WVZ) and beneath the Zlatibor, Bistrica, Sjenički Ozren and Brezovica ophiolites in the Dinaridic ophiolite belt (DOB) in Serbia are...
Article
Full-text available
The Struganik limestone has been increasingly popular in recent years for interior and exterior building applications, due to easy workability, low cost and multi purpose suitability. The quality of limestone is determined by its mineralogical and textural characteristics and physico-mechanical properties. The Struganik stone corresponds to marl, c...
Article
The studied deposits represent the sedimentary cover of ophiolitic mélange of the Western Vardar Zone Belt. An association of sediments that correspond to a primary pyroclastic material occurs in the Upper Cretaceous carbonate sediments near the village of Struganik (Western Serbia). This is an interlayer within mainly carbonate sediments represent...
