Abstract
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 characteristics of the Miocene succession, and applied the U-Pb radiometric dating of volcanic tuffs interstratified in the sedimentary series with coal layers (borehole NRKR- 17002). The obtained concordia age of 16.9 ?0.2 Ma for all the analysed zircon grains without any inherited cores indicate a single magmatic event. We definite the freshwater series originated during Early Miocene Karpatian (= late Burdigalian). Consequently, for the first time, we demonstrated that age of ? part of the Serbian Lake System (SLS) is much older than it was previous reported. In addition, sporadic findings of foraminifers, ostracods and molluscs documented the late Badenian marine transgression in eastern Serbia. If accept this fact the flooding occurred later than in the rest of Serbia (< 14.5 Ma). However, the lack of quality data and unclear stratigraphic position of some parts of the clastic succession (? Lower-Middle Badenian) makes this claim uncertain.
Highlights
The Dacian Basin was a part of the large Paratethyan epicontinental sea (LaSKaREV, 1924)
Facies analyses all of the boreholes drilled the different Miocene units with total thickness up to 600 m (e.g. RTK1501). generally, Miocene succession is composed of clastic rocks
In the same time span a series of Facies analyses, biostratigraphy and radiometric dating of the Lower–Middle Miocene succession near Zaječar (Dacian basin, eastern Serbia) Table 1
Summary
The Dacian Basin was a part of the large Paratethyan epicontinental sea (LaSKaREV, 1924). It covers approximately the domain of the Moesian Platform located in the foreland of the highly bended Carpatho-Balkanides (VaSILIEV, 2006; oLTEaNU & jIPa, 2006; jIPa & oLaRIU, 2009; TER BoRgH, 2013). During the Neogene, the area of eastern Serbia (Timočka Krajina) belonged to the westernmost part of the Dacian Basin which leaned on the Carpathian foothills and the southern branches of the Carpathians and further eastward to Bulgaria and Romania (MaRoVIć et al, 1998; gaNIć, 2005; KNEžEVIć & gaNIć, 2013; TER BoRgH, 2013). Litostratigraphic analyses and correlation with similar sediments of the Intra-Carpathian basins indicated the middle Miocene age of that sediments (e.g. DoLIć, 1977; STEVaNoVIć, 1977). The proposed model of the existence of a large lake system during the Miocene in the territory of Serbia (Serbian Lake System by KRSTIć et al, 2003) has opened numerous challenges of proving or doubting the time span, distribution and genesis of this large lake system (e.g. DoLIć, 1998; RUNDIć et al, 2013; SIMIć et al, 2017; SaNT et al, 2018; MaNDIC et al, 2019)
