The polycyclic Lausche Volcano (Lausitz Volcanic Field) and its message concerning landscape evolution in the Lausitz Mountains (northern Bohemian Massif, Central Europe)

The Mesa of Oybin (Upper Lusatia, Germany) and Its Importance for Geology and Geotourism

“…The whole block was uplifted along the Lusatian fault while the Zittau basin in the North dropped. These motions were most intensive between 1.3 Ma and 340 Ka (Wenger et al, 2017). Today, altitudinal differences are in the order of hundreds meters.…”

“…The Zittauer Gebirge is a deeply eroded block of Cenomanian -Turonian quartz sandstones and gravel conglomerates penetrated with Tertiary volcanic rocks ( Figure 2) connected with the Eger graben very early development (Cajz, 2004, Wenger et al, 2017. Cháb et al, 2007) In the simplified geological map, particular symbols mean: G x are pre-Variscan metagranites, metagranodiorites and orthogneisses; y x pre-Variscan granites and granodiorites; y + Variscan intrusions; f phyllites (uncertain age); B Precambrian green schists; qsKt Lower-Upper Turonian (quartz sandstones); sKts Upper Turonian-Santonian (siltstones, fine sandstones, quartz sandstones; mKts Upper Turonian-Santonian, calcareous claystones and marls; βo olivinic igneous rocks; β1o subaquatic effusions and intrusions (Eger graben); a β1 pyroclastic materials; τβ trachytes; υ phonolites; ab Miocene (Aquitanian-Badenian) -sands, gravels, clay, inferior coal seams.…”

“…The main controlling structure -Lusatian fault -was in detail described by Fediuk et al, (1958) and later Chlupáč (1987) emphasized its importance for vertical movements of peripheral blocks here. Wilmsen with Niebuhr (2014) reviewed the Saxon Upper Cretaceous and other authors (Wenger et al, 2017) summarized the knowledge regarding volcanism in this region, probably the oldest known manifestation of the asymmetric Eger graben (Cajz, 2004). Historical significance of this part of Lusatia was emphasized -for example -by Koláček (2014).…”

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.…”
