To unravel the Mesozoic geodynamic history of the Inner Dinarides
Project
The outcrop at Milivojevića Kamenjar in Družetić (Jadar Block, Vardar Zone, NW Serbia), which exposes a fossiliferous limestone olistolith, is one of the key sites for the Carboniferous stratigraphy and palaeogeography on the Balkan Peninsula. It is the most diverse Carboniferous ammonoid occurrence on the Balkan Peninsula and contains two faunal complexes, an early Late Viséan and a fauna from the Viséan-Serpukhovian boundary. The early Late Viséan assemblage is similar to time equivalent occurrences of the North Variscides and north-western Africa. It is integrated in a cosmopolitan ammonoid distribution of this time interval. The Viséan-Serpukhovian boundary assemblage is very different to its time equivalents from the North Variscides and as a result indicates provincialism; it belongs to the South Variscan–North Gondwanan faunal realm and is closely related to the occurrences in the Cantabrian Mountains of Spain and the South Urals. The two major realms are composed of the following provinces: (1) A south-eastern realm includes (1a) a Uralian-North Gondwanan province (including the South Urals and the Béchar Basin of Algeria) and (1b) a South Variscan province (Cantabrian Mountains and the Jadar Block). (2) A north-western realm is composed of (2a) a North Variscan province (Central Europe, British Isles) and (2b) a North American province (American Midcontinent and Antler Foreland Basin).

In the Dinaridic Ophiolite Belt, small (m-scale) to large (km-scale) blocks of Middle to Upper Triassic, and Middle to Upper Jurassic, more or less silicified bedded limestone are widely present, both as parts of para-autochthonous successions and as redeposited blocks in ophiolitic mélanges. The studied, approximately 230-m-thick succession in the...

The Imperial "retreat palace" Felix Romuliana is predominantly constructed of local and regional rocks. The commonest building material is hornblende andesite available on site and used most extensively for the second fortification. The dimension stones for different parts of the fortifications, for the palace proper and the two temples are of loca...

The conodont stratigraphy, biostratigraphy and carbonate microfacies in the Milivojevića Kamenjar section (Družetić, NW Serbia) are analysed. Based on conodonts and ammonoids, the rock succession spans a period ranging from the late Famennian (Devonian) through to the Serpukhovian (late Mississippian). Nine conodont zones are recorded (one only ten...

Flaked stone artefacts found on the quarry Lojanik in west-central Serbia are good examples of how the function of non-diagnostic pieces could be determined through technological and use-wear analysis. In this study, we present the examples of surface clusters and artefacts from stratigraphic layers. Our attention is focused on the prevailing categ...

Boueina hochstetteri TOULA (type-species of the genus) was published by TOULA (1884) in the 10th report of his travel through the Balkan region. He considered this species to be a problematic organism with uncertain systematic affiliation. Later, STEINMANN (1901) assigned this fossil to the calcareous algae. Our own field work performed in the autu...

The late Middle to early Late Jurassic Hallstatt Mélange in the Inner Dinarides (SW Serbia) plays a crucial role for the reconstruction 1) of the Triassic-Jurassic passive margin configuration of the Western Neo-Tethys Ocean, and 2) of the Middle to Late Jurassic geodynamic history of the Di-narides. In the Zlatar Mountain and adjacent areas, below...

Detail results of microfaunal, sedimentological and geochemical investigations are documented from a newly discovered section of the Permian-Triassic boundary (PTB) interval in the area of the town of Valjevo (northwestern Serbia). The presence of various and abundant microfossils (conodonts, foraminifers, and ostracodes) found in the Upper Permian...

Varied west-transported and far-traveled Jurassic mélanges in southwestern Serbia represent a key to understand the geodynamic history and to solve paleogeographic questions and reconstructions in the Triassic–Jurassic passive and active margin arrangement of the Inner Dinarides. Of special interest are the carbonate-clastic radiolaritic mélange ar...

Oceanic radiolarite components from the Middle Jurassic ophiolitic mélange between Trnava and Rožanstvo in the Zlatibor Mountains (Dinaridic Ophiolite Belt) west of the Drina–Ivanjica unit yield Late Triassic radiolarian ages. The microfacies characteristics of the radiolarites show pure ribbon radiolarites without crinoids or thin-shelled bivalves...

The late Middle to early Late Jurassic mélange of the eastern Zlatibor Mountain (Gostilje–Ljubiš–Visoka–Radoševo areas) in the Dinaridic Ophiolite Belt contains a mixture of (A) blocks of Triassic oceanic crust and radiolarites, and (B) open marine limestone and radiolarite blocks of the overthrusted distal Adria margin. We describe the microfacies...

The scope and importance of utilisation of quartz crystals in the prehistoric period of Serbia were smaller in comparison with cherts, and the reasons for their manufacture and purpose are not sufficiently known. Definition of the origin of quartz crystals from the Grivac site, outside the assumed mine at Mali Šturac, and artefacts from Vinča-Belo...

Systematic study of microfossil associations on the Krivi Potok section (Gučevo Mt. area, NW Serbia) has been carried out to document and to refine the Lower Triassic stratigraphic correlations within Alpine-Mediterranean domain. Field investigation and laboratory process have enabled the identification of lowermost Olenekian (lower Smithian) conod...

Below the Middle to lower Upper Jurassic ophiolitic mélange and their overlying ophiolite nappes of the Dinaridic Ophiolite Belt in the Zlatibor Mountain area occur olistoliths and slide-blocks. These consist of Triassic carbonates and radiolarites of variable age and palaeogeographic provenance. The matrixes of these blocks are late Middle Jurassi...

A kilometer-sized block in the Sirogojno carbonate-clastic mélange provides a complete succession of the Wetterstein Carbonate Platform evolution. The platform starts its progradation in Early Carnian times over hemipelagic Late Ladinian cherty limestones with fine-grained allodapic limestone intercalations. Shallow-water reef-slope, reefal to back...

The paper is dealing with three interpretations of well known section Čerevićki Potok (Fruška Gora Mt., Serbia): 1. According to KOCH, in: PETHÖ (1906), undisturbed succession of 23 lithologically different members, „Hipersenonian“; 2. According to PAŠIĆ (1974; unpublished text is used in monography of PETKOVIĆ et al. 1976), tectonically disturbed...

A peculiar facies of the Norian–Rhaetian Dachstein-type platform carbonates, which contains large amounts of blackened bioclasts and dissolutional cavities filled by cements and internal sediments, occurs in the Zlatibor Mountains, Serbia. Microfacies investigations revealed that the blackened bioclasts are predominantly Solenoporaceae, with a fine...

An attempt was made to describe two parasequences separated within the sediments of the Kotroman Formation at the Mokra Gora Village in western Serbia. The whole formation, of Albian-Cenomanian age, in some general characteristics corresponds to tidal flats, some of which were described in the literature (LARSONNEUR 1975), and the sediments were co...
