A new U–Pb LA-ICP-MS age of the Rumburk granite (Lausitz Block, Saxo-Thuringian Zone): constraints for a magmatic event in the Upper Cambrian

Provenance of the early Palaeozoic volcano-sedimentary successions from eastern part of the Central Sudetes: implications for the tectonic evolution of the NE Bohemian Massif

“…Dörr et al 2002) are consistent with the inferred hot conditions of the KMB rhyolitic magma generation and correlate with intrusions into transitional crust at the peripheries of Gondwana that were postulated by tectonic model of Linnemann (2007) for the late Cambrian in the Saxothuringia (e.g. Zieger et al 2018).…”

“…Fernández-Suárez et al 2002; Linnemann, 2007; Linnemann et al 2008; Žáčková et al 2010; Drost et al 2011; Mazur et al 2012; Košler et al 2014; Strachan et al 2014; Soejono et al 2020). The youngest population of zircon grains recognized in the metasedimentary succession analysed from the DMC was probably derived from the erosion of Cambro-Ordovician granites widely exposed in the Saxothuringian (Zieger et al 2018 and references therein), Teplá-Barradian (e.g. Žák et al 2013) and Moldanubian zones (Žák et al 2023).…”

“…490 to 520 Ma were most likely supplied by Cambrian granites known from the Sudetes exemplified by, for example, Śnieżnik or Izera orthogneiss (e.g. Turniak et al 2000; Lange et al 2005; Mazur et al 2010; Zieger et al 2018). Neoproterozoic grains could have been derived from granitoid intrusions dated at c. 540 Ma that were reported from several fragments of Cadomian basement exposed in the Bohemian Massif (Linnemann & Heuse, 2001; Tichomirowa et al 2001; Mingram et al 2004; Żelaźniewicz et al 2004; Jastrzębski et al 2021; Tabaud et al 2021; Śliwiński et alet al 2022; Soejono et al 2022).…”

“…Although metagranitoids from the Izera-Karkonosze Massif have a chemical composition typical of volcanic arc granites (e.g. Turniak et al 2000; Zieger et al 2018), Oberc-Dziedzic et al (2005) and Pin et al (2007) interpreted them on the basis of Sm-Nd isotopic data and bulk rock geochemistry as either typical S-type post-collisional or anorogenic and related to continental break-up. The latter idea and the relationship of the metagranitoids to continental break-up was recently supported by Jastrzębski et al (2017).…”

Two-phase late Paleozoic magmatism (~ 313–312 and ~ 299–298 Ma) in the Lusatian Block and its relation to large scale NW striking fault zones: evidence from zircon U–Pb CA–ID–TIMS geochronology, bulk rock- and zircon chemistry

“…A homogenization of the Hf-isotopic composition in zircon requires an almost complete dissolution of inherited zircons (Farina et al 2014). However, inherited zircons are abundant in all Cadomian basement rocks of the Bohemian Massif (e.g., Tichomirowa et al 2001Tichomirowa et al , 2012Tichomirowa 2002;Friedl et al 2004;Białek et al 2014;Zieger et al 2018). In addition to frequent inherited zircons, all rocks from the Cadomian basement have very heterogeneous zircon Hf-and O-isotope composition as shown for the Saxothuringian basement of the Erzgebirge (Tichomirowa et al 2018) and of the Schwarzburg Antiform (Linnemann et al 2014).…”
