Quartz c-axis fabrics in constrictionally strained orthogneisses: implications for the evolution of the Orlica-Śnieżnik Dome, the Sudetes, Poland

“…Such an inference is consistent with all P-T estimates calculated by various methods for mica schists and other multiply deformed metasedimentary rocks of the Stronie-Młynowiec group in either limb of the Orlica-Śnieżnik Dome (Jastrzębski et al 2010;Szczepański 2010;Skrzypek et al 2011). They indicate the peak metamorphic P-T conditions occurred in the OSD metasedimentary and metavolcanic rocks at 560-620°C/7-9 kbar (Jastrzębski 2005(Jastrzębski , 2009Murtezi 2006;Skrzypek et al 2011), apparently at 340 Ma (Skrzypek, pers. comm., Jastrzębski et al 2013); thus the data are in agreement with the microstructural proxies.…”

From Cadomian arc to Ordovician passive margin: geochemical records preserved in metasedimentary successions of the Orlica-Śnieżnik Dome in SW Poland

“…The tectonometamorphic evolution of the Polish part of the OSD involved between three and five tectonometamorphic events related mainly to the Variscan collisional episode and crustal-scale folding (e.g., Murtezi 2006;Jastrzębski 2009;Szczepański 2010aSzczepański , 2011aSkrzypek et al 2011a, b;Chopin et al 2012). Variscan metamorphism is partly characterized by a Barrovian zonal pattern with biotite-, garnet-, staurolite-, kyanite-and sillimanite zones developed (Opletal and Domečka 1983;Jastrzębski 2009;Szczepański 2010a;Chopin et al 2012).…”

An insight into a gneiss core of the Orlica-Śnieżnik Dome, NE Bohemian Massif: new structural and U–Pb zircon data

“…The age of ~350 Ma is also iden ti cal with the meta mor phic cli max af ter the main deformational event in mica schists that oc curred at ~352-346 Ma (Gordon et al, 2005;Jastrzêbski, 2009;Jastrzêbski et al, 2010) and at ~360 Ma in rocks of the bor der land be tween the Saxothuringian/Mol danubian and Brunovistulian ter ranes along the east ern mar gin of the Orlica-OEnie¿nik Dome . Relicts of the blueschist fa cies meta mor phism in the west ern limb of the dome would im ply that at least part of the metasedimentary rocks, which man tle the gneissic core of this unit, was sub jected to HP con di tions of ~20-21 kbar at 500-550°C (Faryad and Kachlík, 2013) prior to the ther mal peak meta mor phism at lower pres sures.…”

“…The old est fo li a tion that fol lowed bed ding planes in the metasedimentary man tle rocks was folded and trans posed to the subvertical ax ial pla nar fo li a tion due to an early E-W subhorizontal short en ing and then re folded dur ing subvertical short en ing. Such tec tonic tem plate is fa voured by most au thors al though iden ti fi ca tion and la bel ling of con sec u tive struc tures dif fer in de tails (Dumicz, 1979;Jastrzêbski, 2005Jastrzêbski, , 2009Murtezi, 2006;Skrzypek et al, 2011Skrzypek et al, , 2014Cho pin et al, 2012a, b). Sim i lar struc tural suc ces sion is of ten as sumed for the core gneiss es, which seems con tro versial and not nec es sar ily cor rect (¯elaŸniewicz at al., 2014a, b).…”
