Abstract This paper summarizes the current knowledge on nature, kinematics and timing of movement along major tectonic boundaries in Bohemian Massif demonstrates how Variscan plutonism deformation evolved space time. Four main episodes are recognized: (1) Late Devonian–early Carboniferous subduction continental underthrusting Saxothuringian Unit beneath Teplá–Barrandian resulted orogen-perpendicular shortening growth an inboard magmatic arc during c. 354–346 Ma; (2) subduction-driven was...
Abstract Blueschist facies rocks, exposed within consolidated continental blocks, provide some of the best evidence for existence previous suture(s). They usually occur as lenses or layers embedded greenschist amphibolite rocks and indicate reequilibration at medium‐ to low‐pressure conditions. In Bohemian Massif, a few occurrences blueschists have been reported, here, new high‐pressure (HP) metamorphism in various lithologies is presented that suggests larger extent blueschist along...
Abstract Field relationships combined with new U‐Pb zircon geochronology suggest that the shallow‐level Krkonoše‐Jizera plutonic complex, northern Bohemian Massif, was assembled successively from bottom to top, starting emplacement of separately evolved S‐type Tanvald granite (317.3 ± 2.1 Ma), followed by at least two voluminous batches I‐type porphyritic Liberec (319.5 2.3 Ma) and Jizera (320.1 3.0 Ma 319.3 3.7 granites. The intrusive sequence completed uppermost, minor intrusions...
Abstract Corona and inclusion textures of a metatroctolite at the contact between felsic granulite migmatites Gföhl Unit from Moldanubian Zone provide evidence magmatic metamorphic evolution rocks. Numerous diopside inclusions (1–10 μ m, maximum 20 m in size) plagioclase anorthite composition represent primary textures. Triple junctions grains matrix are occupied by amphibole, probably pseudomorphs after clinopyroxene. The coronae consist core orthopyroxene, with two or three zones (layers);...
Abstract The West Sudetes (NE margin of the Bohemian Massif) consist a complex mosaic several tectonometamorphic units juxtaposed during Variscan orogeny. polyphase tectonothermal development was determined by 40 Ar/ 39 Ar ages single grains and mineral concentrates. Late Famennian (359 Ma) mica from high-grade Góry Sowie Block suggest continuous uplift after Devonian high temperature-low pressure (HT-LP) event contemporaneous with end subduction-related pressure-low temperature (HP-LT)...
Knowledge of the origin magnesium (Mg) and calcium (Ca) in soil solutions catchment runoff helps to predict forest ecosystems’ vulnerability deficiencies essential nutrients an era climate change, environmental pollution bark-beetle calamities. Here we discuss isotope aspects Mg, Ca strontium (Sr) cycling a spruce-forested headwater relatively unpolluted part Central Europe. We investigated what extent Mg signatures reflect compositions specific Mg- Ca-rich minerals that easily dissolve...
Abstract Fault‐bounded coherent belts alternating with of mélanges are common in accretionary wedges and usually interpreted as a result imbrication along subduction zone megathrusts. Using the Neoproterozoic/early Cambrian Blovice complex ( BAC ), Bohemian Massif, case example, we present new model for origin through repetition several cycles (1) offscraping deformation trench‐fill sediments to form units, interrupted by (2) arrival linear, trench‐parallel volcanic elevations. The latter...
