The landscape evolution of the Lausitz Block since the Palaeozoic – with special emphasis to the neovolcanic edifices in the Lausitz Volcanic Field (Eastern Germany)

The Stolpen Volcano in the Lausitz Volcanic Field (East Germany) - volcanological, petrographic and geochemical investigations at the type locality of basalt

“…Therefore, the Stolpen Volcano is moderately dependent on the elevation of the landscape and climatic conditions which control ground water level and quantity. This indicates that the genesis of the Stolpen Volcano took place during a time of low ground levels (peneplain) and voluminous aquifers (humid-tropical climate), conforming well with the explanations given by Tietz and Büchner (2015).

“…The main uplift took place between 85 and 50 Ma, what caused denudation of c. 3,000-3,500 m (Lange et al 2008; see also Hofmann et al 2018). Tietz and Büchner (2015) used volcanic edifices and related Quaternary deposits to determine the younger uplift und denudation history of the Lausitz Block, demonstrating an uplift of up to 100 m (2-3 mm/kyr) since the volcanism at 30 Ma. These neotectonic movements started at 1.3 Ma with a climax at 320 ka, following the Elsterian Glaciation (e.g., Wenger et al 2017).…”

“…However, it is not possible to determine whether lava flowed out of the crater because all potential lava flows would have been completely eroded by now. If lava flows had existed, the pre-volcanic surface may have been lower than presumed, at about 370 m a. s. l. The amount of eroded material can be calculated assuming that uplift was constantly balanced by denudation and that the former surface of the land was nearly flat and horizontal (Tietz and Büchner 2015). Close to the Stolpen Volcano, the surface has been lowered via erosion by 65 meters.…”

Emplacement History of the Miocene Zebín Tuff Cone (Czech Republic) Revealed From Ground Geophysics, Anisotropy of Magnetic Susceptibility, Paleomagnetic, and 40Ar/39Ar Geochronology Data

“…Most of the magmatism was concentrated along the Eger Rift, which represents the eastern most branch of the European Cenozoic Rift System (Figure ; e.g., Dèzes et al, ; Rajchl et al, ). Apart from the main volcanic complexes (see, e.g., Rapprich & Holub, ; Cajz et al, ; Skála et al, ; Ackerman et al, ), several volcanic fields were also formed on the shoulders of the rift (Awdankiewicz, ; Awdankiewicz et al, ; Büchner & Tietz, ; Büchner et al, ; Haase et al, ; Petronis et al, ; Rapprich et al, ; Tietz & Büchner, ; Valenta, Rapprich, Skácelová, Gaždová, & Fojtíková, ; Wenger et al, ). Our study focused on the Zebín Volcano, located in the Jičín Volcanic Field (Rapprich et al, ; Figure ) in the southeast of the Eger Rift, where Miocene volcanic rocks were emplaced into, or erupted onto, Upper Cretaceous marine sediments of the Bohemian Cretaceous Basin and continental Permo‐Carboniferous strata of the Krkonoše Piedmont Basin.…”

Fingerprints of magma mingling processes within the Miocene Zebín tuff cone feeding system (Jičín Volcanic Field, Czech Republic)

“…Most of the magmatism was concentrated along the Eger Rift, which represents the easternmost branch of the European Cenozoic Rift System (e.g., Dèzes et al 2004;Rajchl et al 2008). Apart from the main volcanic complexes (see e.g., Ulrych et al 2002;Rapprich and Holub 2008;Cajz et al 2009;Holub et al 2010;Skála et al 2014;Ackerman et al 2015), several volcanic fields were formed also on the shoulders of the rift (Awdankiewicz 2005;Rapprich et al 2007;Büchner and Tietz 2012;Valenta et al 2014;Büchner et al 2015;Petronis et al 2015;Tietz and Büchner 2015;Awdankiewicz et al 2016;Ulrych et al 2016;Haase et al 2017). Our study focused on the Zebín Volcano, located in the Jičín Volcanic Field (Rapprich et al, 2007;Petronis et al 2015; Fig.…”
