“…This zircon population is not characteristic for the Armorican/West African Craton provenance (e.g., Linnemann et al 2007;Abati et al 2012;Gärtner et al 2013Gärtner et al , 2016Henderson et al 2016). Nevertheless, a small number of Mesoproterozoic ages were also described from the Armorican Quartzites of the Cantabrian Zone of NW Iberia (Fernández-Suárez et al 2002;Guttiérrez-Alonso et al 2007), as well as from the Ordovician sandstones of Corsica (Avigad et al 2018). Perhaps, the presence of Mesoproterozoic zircons in the NGU Pennsylvanian-Permian sequence, at least in small proportions, indicates a possible presence of the pre-Neoproterozoic crustal vestiges that were accreted within the Western Carpathian Variscan orogenic domain.…”

The Late Paleozoic sedimentary basins in the Northern Gemericum evolved gradually in time and space within the collisional tectonic regime of the Western Carpathian Variscan orogenic belt. The detrital zircon age spectra, obtained from the Mississippian, Pennsylvanian and Permian metasediments, have distinctive age distribution patterns that reflect the tectonic setting of the host sediments. An expressive unimodal zircon distribution, with an age peak at 352 Ma, is shown by the basal Mississippian metasediments. These represent a relic of the convergent trench-slope sedimentary basin fill. In comparison, the Pennsylvanian detrital zircon populations display distinct multimodal distributions, with the main age peaks at 351, 450, 565 Ma and smaller peaks at ~2.0 and ~2.7 Ga. This is consistent with derivation of clastic detritus from the collisional suture into the foreland basin. Similarly, the Permian sedimentary formations exhibit the multimodal distribution of zircon ages, with main peaks at 300, 355 and 475 Ma. The main difference, in comparison with the Pennsylvanian detrital zircon assemblages, is the sporadic occurrence of the Kasimovian– Asselian (306–294 Ma), as well as the Artinskian–Kungurian (280–276 Ma) igneous zircons. The youngest magmatic zircon ages nearly correspond to the syn-sedimentary volcanic activity with the depositional age of the Permian host sediments and clearly indicate the extensional, rift-related setting.

“…Generally, the Armorican age spectrum contains more Ediacaran ages than Cryogenian ones, with typical latest age peaks from 540 Ma to 570 Ma of the Cadomian active margin and with a distinctive Mesoproterozoic age gap (e.g. Fernández-Suárez et al 2002Friedl et al 2004;Linnemann et al 2004Linnemann et al , 2008Drost et al 2011;Shaw et al 2014;Dörr et al 2015;Henderson et al 2016;Avigad et al 2018).…”

U–Pb (SHRIMP) detrital zircon ages from the Early Paleozoic meta-sedimentary rocks of the Northern Gemericum Unit (the Smrečinka Formation) were used to characterize their provenance. The aim was to compare and reconcile new analyses with previously published data. The detrital zircon age spectrum demonstrates two prominent populations, the first, Late Neoproterozoic (545–640 Ma) and the second, Paleoproterozoic (1.8–2.1 Ga), with a minor Archean population (2.5–3.4 Ga). The documented zircon ages reflect derivation of the studied metasedimentary rocks from the Cadomian arc, which was located along the West African Craton. The acquired data supports close relations of the Northern Gemericum basement with the Armorican terranes during Neoproterozoic and Ordovician times and also a close palinspastic relation with the other crystalline basements of the Central Western Carpathians. In comparison, the detrital zircons from the Southern Gemericum basement and its Permian envelope indicate derivation from the Pan-African Belt–Saharan Metacraton provenance.
