20.500.12556/RUL-137746 Geochemistry of Bashibos-Bajrambos metasedimentary unit, Serbo-Macedonian massif, North Macedonia implications for age, provenance and tectonic setting Metasediments of the Paleozoic Bashibos-Bajrambos unit, comprising the western perimeter of the Serbo-Macedonian Massif in SE Republic of North Macedonia, were investigated by employing whole-rock geochemistry and detrital zircon geochronology to put constraints of age, provenance and depositional tectonic setting. The metasedimentary unit consists of polymetamorphic and highly altered pelitic mica-schists and phyllites and metamafic rocks. The first limited data from the whole-rock composition of the metapelites and zircon Th/U ratios suggest derivation of detrital material from felsic and recycled older upper crustal sources. At the same time, mafic samples indicate an origin from a volcanic source without a significant contribution from ultramafic rocks. Whole-rock data and the detrital zircon record suggest that deposition of the sequence took place in collision-related, foreland basin, formed by the merging of Pelagonian and the Serbo-Macedonian Massifs. The population of the youngest recorded zircons indicates Early Permian sedimentation. The detrital zircon record speaks for significant sedimentary input of old crustal material from the Serbo-Macednonian Massif, while younger Carboniferous-Permian magmatic zircon populations support the significant influence of the Pelagonian Massif. geochemistry provenance tectonic setting detrital zircon dating Serbo-Macedonian Massif true false true Angleški jezik Ni določen Članek v reviji 2022-06-30 08:20:31 2022-06-30 08:20:32 2024-03-13 15:41:43 0000-00-00 00:00:00 2020 0 0 21 str. iss. 4, art. 125664 Vol. 80 Dec. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 502/504 0009-2819 10.1016/j.chemer.2020.125664 18539779 1-s2.0-S0009281920300738-main.pdf 1-s2.0-S0009281920300738-main.pdf 1 8E8A928F2126698C0756F193F6AB2A8B f04086d71251f4dfb71651728ccbfc02dd6b687b6e38dd94a71918e4e64c2f39 a7c43476-f83e-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157812 https://www.sciencedirect.com/science/article/pii/S0009281920300738 0 b109c1f5-f83c-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157809 Naravoslovnotehniška fakulteta 0 0 0
