Sedimentary record of subaerial volcanic activity in the basal Ordovician shoal-marine deposits: the Třenice Formation of the Prague Basin, Bohemian Massif, Czech Republic

Lingulate Brachiopods of Tremadocian Age from the Abandoned Gabriela Mine (Krušná Hora, Central Bohemia, Czech Republic)

“…Therefore, the newly observed brachiopod occurrence is assumed to be allochtonous unlike to parautochtonous occurrences of Hyperobolus in the lithic sandstone in another stratigraphic levels. Unlike to newly described fauna, the shells of Hyperobolus feistmanteli are generally oriented parallel to bedding planes and are less intensively fragmented indicating only moderate transport and wave and current generated orientation in sand dunes (Hroch et al 2012).…”

Metamorphic inheritance of Rheic passive margin evolution and its early‐Variscan overprint in the Teplá‐Barrandian Unit, Bohemian Massif

“…485 Ma metamorphic event in the TCC temporally overlaps the Ordovician unconformity in the Prague basin (Figs b & b). This is evident in the composition of basal Ordovician conglomerates that were partly derived from still active, but decaying Late Cambrian volcanism into a shallow water environment (Hroch et al ., ). The thermal relaxation and cessation of magmatic/volcanic activity in the TCC after the metamorphic peak at c .…”

“…Such an interpretation can be correlated with the existing data on the early Palaeozoic evolution of the Prague basin east of the Teplá‐Barrandian domain (e.g. Drost et al ., , ; Hroch et al ., and references therein; Žák et al ., ) that remained unaffected by the Variscan metamorphism (Fig. b).…”

Interactions between distal epiclastic and bio‐chemogenic sedimentation at the foothills of a mafic alkaline volcano: The case of the Oligocene Doupovské Hory Volcanic Complex (Czech Republic)

“…Volcanoes are frequently associated with sedimentary basins, which they supply with clastic material (Di Capua & Groppelli, 2018; Hroch et al, 2012; Kataoka et al, 2009; Manville et al, 2009; Martí et al, 2018; Novo et al, 2018; Ollier et al, 1998; White & Riggs, 2009). Desublimation of volcanic gases may deposit significant amounts of chemical deposits, such as travertine (Garavelli et al, 1997).…”
