Terra Nova, 24, 199–206, 2012 Abstract Three detrital zircon concentrates from the metasediments of Orlica‐Śnieżnik dome, Bohemian Massif, have been dated using Sensitive High Resolution Ion Microprobe. They yielded Precambrian age spectra similar to those that are characteristic Cadomian terranes: (1) Archaean and Palaeoproterozoic zircons scattered between 3380 1860 Ma, (2) abundant Neoproterozoic at 770–560 Ma. Two analysed samples also contain Early Cambrian Early‐Late zircons. The...
Abstract Seven granitoid gneisses from the contact zone between eastern margin of Variscan belt and Brunian microcontinent in SW Poland have been dated by ion-microprobe 207 Pb/ 206 Pb single zircon evaporation methods. The zircons define two age groups for gneiss protoliths: (1) late Neoproterozoic c. 576–560 Ma (2) early Palaeozoic 488–503 granites. belonging to basement contain abundant Mesoproterozoic latest Palaeoproterozoic inherited material range 1200–1750 Ma. crustal domain lack...
The Orlica-Snieznik Dome (OSD) is located in the northeastern part of Bohemian Massif and interpreted as a fragment Moldanubian zone within Variscan orogen, representing orogenic root. dome composed primarily orthogneisses interspersed with metamorphosed volcano-sedimentary sequences. In Snieznik Massif, which forms eastern segment OSD, lenses high- ultrahigh-pressure (UHP) rocks, including granulites eclogites, are embedded orthogneisses. This study investigates metamorphic evolution...
We investigated paragneisses from the Wyszki and Młynowiec Formations mica schists of Stronie Formation volcano-sedimentary successions Orlica-Śnieżnik Dome (OSD) in Central Sudetes. Phase equilibria modeling quartz-in-garnet elastic barometry were employed to directly compare metamorphic histories western eastern parts OSD using consistent methodologies. Our study is based on detailed analyses nine samples, including three six schists.The studied experienced...
The Lower Silesian Block outcrops in the NE part of Bohemian Massif with its northeasternmost fragment, Fore-Sudetic Block, buried under Cenozoic sediments. AMINV K-1 borehole drilled 2013 and located this area provides a unique insight into geology scarcely exposed Variscan crystalline basement. profile exhibits metamorphosed volcano-sedimentary sequence composed mainly quartz-rich schists, chlorite-schists mica schists garnet-rich layers covered 100 m Paleogene sediments. In...
Abstract A section of the orogenic middle crust (Orlica‐Śnieżnik Dome, Polish/Czech Central Sudetes) was examined to constrain duration and significance deformation (D) intertectonic (I) phases. In studied metasedimentary synform, three events produced an initial subhorizontal foliation S1 (D 1 ), a subsequent subvertical S2 2 ) late axial planar cleavage S3 3 ). The synform intruded by pre‐, syn‐ post‐D granitoid sheets. Crystallization–deformation relationships in mica schist samples...
The chemical composition of metamorphosed siliciclastic rocks in the Orlica-Śnieżnik Dome (Bohemian Massif) identifies main sources for Neoproterozoic [the Młynowiec Formation (MF)], Early Cambrian Stronie (SF)] and Late Cambrian/Early Ordovician Goszów quartzites (GQ)] sediments. MF developed from erosion a Cadomian magmatic arc along northern Gondwana margin. variegated SF, with supra-subduction affinities, shows characteristics pointing to freshly exhumed orogen detritus deposition...

The idea behind this study was to assess the sorption capacity of shale rocks as potential CO2 storage sites. Thinly laminated mudrocks (gas bearing shales from Baltic Basin) with matrix composed mostly illite, K-mica and chlorites varying amount organic matter were selected for study. Results measurements up pressure 15 MPa at temperature 50°C 80°C compared XRD compositional analysis samples TOC values. Our experiments demonstrate that when is nearly absent in mudstones may also occur clay minerals.
Abstract We studied the petrographical characteristics and bulk chemical composition along with age of detrital zircon grains from quartzites exposed in western part Orlica-Śnieżnik dome Saxothuringian zone. Age spectra zircons were obtained by U–Pb laser ablation inductively coupled plasma mass spectrometry dating. The ages define a few clusters which most numerous are Cambro-Ordovician Neoproterozoic, less frequent Paleoproterozoic Archean. A distinctive feature investigated samples is...
Abstract This paper aims to analyse electrical conduction in partially sintered porous materials using an original resistor network model within discrete element framework. The is based on sintering geometry, where two particles are connected via neck. Particle-to-particle conductance depends neck size materials. Therefore, accurate evaluation of essential determine conductance. was determined volume preservation criterion. Additionally, grain boundary correction factor introduced compensate...
Abstract The Kamieniec Metamorphic Belt belongs to the Variscan of Europe as NE part Bohemian Massif. It comprises a supracrustal succession dominated by micaschists that has not been yet recognized high‐ P , low‐ T ( HP – LT ) metamorphic unit. Our work demonstrates significance metapelites in study metamorphism To reconstruct P–T history Belt, we have investigated three samples using independent geothermobarometric techniques including phase diagram modelling, Si 4+ content white mica and...
Abstract The Kamieniec Metamorphic Belt (KMB) and the Doboszowice Complex (DMC) expose a fragment of pre-Variscan volcano-sedimentary cover preserved in Fore-Sudetic Block NE part Bohemian Massif. We present age detrital magmatic zircon grains bulk rock chemical composition samples from KMB DMC to better understand evolution early Palaeozoic Gondwana margin. spectra were acquired by U–Pb LA–ICP–MS dating represent two groups that differ maximum depositional (MDA). paragneiss displays MDA at...
