Heavy minerals from sedimentary rocks of the Malcov Formation and their palaeogeographic implications for evolution of the Magura Basin (Western Carpathians, Slovakia) during the Late Eocene – Late Oligocene

Heavy minerals and exotic pebbles from the Eocene flysch deposits of the Magura Nappe (Outer Western Carpathians, eastern Slovakia): their composition and implications on the provenance

“…The geological composition of the Silesian Ridge varied from north to south (Soták, 1992;Budzyń et al, 2008Budzyń et al, , 2011 and did not relate to the Bohemian Massif (Soták, 1990).

“…Oligocene deposits mainly in the RU could be derived from the Marmarosh Massif and also the Fore-Marmarosh Suture. For the KU, a significant contribution of detrital material from medium-to highgrade metamorphic complexes of the Villáni-Bihor and Békés-Codru zones (crystalline basement of the Tisza Mega-Unit) was proposed by Bónová et al (2016). Part of the clastic material could be redeposited from older flysch formations (l. c.).…”

“…Previous provenance studies on the Palaeogene deposits from the eastern part of the Magura Nappe (Flysch Belt, Outer Western Carpathians) were focused on either petrography of major framework grains (Ďurkovič, 1960, 1961, 1962) or on exotic pebble composition (Leško and Matějka, 1953;Wieser, 1967;Nemčok et al, 1968;Marschalko, 1975;Oszczypko, 1975;Marschalko et al, 1976;Mišík et al, 1991a;Oszczypko et al, , 2016Olszewska and Oszczypko, 2010). Based on heavy mineral suites, the provenance has been also investigated (Ďurkovič, 1960Starobová, 1962), and recently more detailed results were reported from electron microprobe analyses (e.g., Salata, 2004;Oszczypko andSalata, 2004, 2005;Bónová et al, 2016Bónová et al, , 2017.…”
