Base ment struc ture of the Pa leo zoic Plat form in Po land. Geo log i cal Quar terly, 61 (2): 502-520, doi: 10.7306/gq.XXXX The Pa leo zoic Plat form com prises the south west ern half of the Pol ish ter ri tory, sep a rated from the Pre cam brian East Eu ropean Plat form (EEP) by a NW-SE trending subvertical lithospheric-scale dis con ti nu ity -the Teisseyre-Tornquist Zone. In the pres ent study, the Pa leo zoic Plat form base ment is sub di vided based on geo log i cal and geo phys i cal ev i dence ac quired dur ing the last de cades, in clud ing deep seis mic re frac tion and re flec tion re sults, as well as grav ity, mag netic and magnetotelluric data. The units ad ja cent to the EEP, the Mid-Pol ish Do main (com pris ing the £ysogóry Block) and the Pom era nian Block, are char ac ter ized by a thinned three-layer EEP-type crys tal line crust (age 1.7-3.7 Gy). Their old est plat form cover is prob a bly com posed of thick Ediacaran syn-rift sed i men tary and vol ca nic rocks. Their west ern ex ten sion in the contig u ous Ger man and Bal tic area can be traced as far as the East Elbian Mas sif and Thor Su ture based mainly on mag netic anom aly pat terns. The Up per Silesian and Ma³opolska blocks lo cated in SE Po land are char ac ter ized by Cadomian (660-600 My) base ment over lain by the thick de formed Ediacaran foredeep de pos its. Whereas the units with the EEP-type base ment are in ter preted as prox i mal ter ranes dis placed along the EEP mar gin dur ing the late Early Pa leo zoic, the blocks with a Cadomian base ment are con ceived as ex otic ter ranes of a pos si ble Gondwanan prov e nance. All these ter ranes were accreted ul ti mately dur ing the fi nal, lat est Si lu rian stages of the Cal edo nian de for ma tion al though the ex act sce nario of the amal gam ation re mains hy po thet i cal. The Sudetic Do main in SW Po land is a col lage of dif fer ent crustal units jux ta posed ul timately in the Penn syl va nian (ca. 310 Ma) dur ing the fi nal ep i sodes of the Variscan Orog eny. Their north ern bound ary cor responds to the Rheic Su ture trace able in mag netic and grav ity anom a lies pat tern along the north ern mar gin of the Wolsztyn-Leszno High, and con tin u ing west wards along the Mid-Ger man Crys tal line High. The ar cu ate trace of the su ture in the NE is dextrally dis placed along the Odra Fault, and con tin ues south wards where it is mapped as the Moravian-Silesian Su ture.

“…Both the Danish Basin and the North German Basin were initiated in relation to these magmatic and tectonic events. Lithospheric stretching in the thermally weakened crust-upper-mantle formed an important basin-generating mechanism leading to deep sedimentary basins (Van Wees et al 2000;Frederiksen et al 2001;Scheck-Wenderoth & Lamarche 2005;McCann et al 2006). The Oslo-Skagerrak rift and graben system were also formed as part of these events.…”

Upper-mantleP- andS-wave velocities across the Northern Tornquist Zone from traveltime tomography

et al. 2015

S U M M A R YThis study presents P-and S-wave velocity variations for the upper mantle in southern Scandinavia and northern Germany based on teleseismic traveltime tomography. Tectonically, this region includes the entire northern part of the prominent Tornquist Zone which follows along the transition from old Precambrian shield units to the east to younger Phanerozoic deep sedimentary basins to the southwest. We combine data from several separate temporary arrays/profiles (276 stations) deployed over a period of about 15 yr and permanent networks (31 stations) covering the areas of Denmark, northern Germany, southern Sweden and southern Norway. By performing an integrated P-and S-traveltime analysis, we obtain the first high-resolution combined 3-D V P and V S models, including variations in the V P /V S ratio, for the whole of this region of study. Relative station mean traveltime residuals vary within ±1 s for P wave and ±2 s for S wave, with early arrivals in shield areas of southern Sweden and later arrivals in the Danish and North German Basins, as well as in most of southern Norway. In good accordance with previous, mainly P-velocity models, a marked upper-mantle velocity boundary (UMVB) is accurately delineated between shield areas (with high seismic mantle velocity) and basins (with lower velocity). It continues northwards into southern Norway near the Oslo Graben area and further north across the Southern Scandes Mountains. This main boundary, extending to a depth of at least 300 km, is even more pronounced in our new S-velocity model, with velocity contrasts of up to ±2-3 per cent. It is also clearly reflected in the V P /V S ratio. Differences in this ratio of up to about ±2 per cent are observed across the boundary, with generally low values in shield areas to the east and relatively higher values in basin areas to the southwest and in most of southern Norway. Differences in the V P /V S ratio are believed to be a rather robust indicator of upper-mantle compositional differences. For the depth interval of about 100-300 km, thick, depleted, relatively cold shield lithosphere is indicated in southern Sweden, contrasting with more fertile, warm mantle asthenosphere beneath most of the basins in Denmark and northern Germany. Both compositional and temperature differences seem to play a significant role in explaining the UMVB between southern Norway and southern Sweden. In addition to the main regional upper-mantle velocity contrasts, a number of more local anomaly features are also outlined and discussed.

“…Subsequent to the Variscan Orogeny during the Westphalian basin formation took place in the Stephanian-Autunian in both the internal and external Variscides. Approximately 70 basins developed in the Western and Central Europe within a relatively short time span (McCann et al, 2006). Most of these basins trace long-lived Variscan fault systems.…”

The deposits of the Upper Carboniferous to Lower Permian Zöbing Formation in Lower Austria have been studied by a wide range of sedimentological methods in several limited outcrops. Four facies associations were identified: (a) non-channelized finegrained deposits; (b) channelized sandstones, (c) non-channelized conglomerates, and (d) channelized conglomerates. Non-channelized fine-grained sediments are interpreted as deposits in shallow, semi-permanent pools on floodplains. Channelized sandstones are associated with fluvial processes and mostly represent crevasse channels cut into the floodplains. Channelized conglomerates originated from coarse-grained confined and hyperconcentrated flows. Non-channelized conglomerates are interpreted as sediments of alluvial fan and alluvial plain systems. A terminal fluvial system developed under a semi-arid to arid climatic regime is supposed to be the depositional environment of the Zöbing Formation.The detritus was mostly derived from primary sources formed by crystalline rocks. The proportion of metamorphites (particularly metapelitic rocks, such as mica schists, paragneisses, felsitic granulites) was predominant along with acidic magmatic and volcanic rocks. The source area predominantly can be located in the Moldanubian unit. Rapid physical erosion, redeposition and subordinately also chemical weathering are all supposed in the source area. The general provenance evolution of the entire Zöbing Formation shows local/adjacent sources in the basal parts whereas a wider provenance and variations in the primary and recycled detritus are assumed for the younger parts of the succession.________________________________________________________
