“…It can be as sumed, how ever, that it con forms with the Peri-Pieniny Fault Zone (Bu³a and ¯aba, 2008) sep a rat ing the Outer and In ner Carpathians. The NE bound ary with the Ma³opolska Block cor re sponds to the Kraków-Lubliniec Fault (Bu³a et al, 1997). The fault is in ter preted as a pre-De vo nian accretionary su ture re ac ti vated dur ing a Variscan transtension-transpression, with as so ci ated bi modal late-and post-orogenic magmatism (Moczyd³owska, 1997;¯aba, 1999;Belka et al, 2002;S³aby et al, 2010).…”

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.

Possible origin of stromatactis-like cavities in Upper Jurassic sediments from the Wielkanoc quarry near Gołcza (Kraków–Częstochowa Upland, southern Poland)—experimental studies

Isolated stromatactis-like cavities were found in a microbial-sponge buildup exposed in the Wielkanoc quarry (eastern part of the Kraków-Częstochowa Upland). The cavities are filled with several generations of carbonate cements and with internal sediments. The top surfaces of internal sediments are flat or wavy, whereas the roofs of cavities are arcuate. The origin of cavities from the Kraków-Częstochowa Upland is difficult to constrain. It seems that the stromatactis-like cavities from the Wielkanoc quarry resulted, at least partly, from remodeling of open spaces left after dissolution of corals in incompletely lithified sediment. Dissolution of corals disturbed the primary stress field within the carbonate buildup and generated the secondary stress characterized by the appearance of compressional forces in the walls of cavities and tensional forces in their roofs. Thus, the lack of support of sediments over roofs of cavities after dissolution of corals resulted in their instability and collapse triggered by vibrations caused by various factors. One of such triggers might have been the rejuvenation of the Kraków-Lubliniec Fault Zone in the Late Jurassic or the collapse of reticular framework within the buildup. The material falling down from the roofs was deposited at the bottoms of cavities as an internal sediment.Results of experimental studies demonstrate that the arcuate shapes of the roof surfaces of cavities are related to compressional stress in the walls and tensional stress in their roofs.

“…The litological and facial differences in the Ordovician and Silurian deposits appear in the discrepancy on older strata. They occur as isolated areas, under the cover of incomplete Devonian, Carboniferous and Mesozoic strata (Buła et al 1997, 2002, Żaba 1999, Buła 2000, Jachowicz & Buła eds. 2010, Buła & Habryn 2011.…”

Abstract:The geochemical characteristics of the Palaeozoic and Mesozoic strata of the basement of the Carpathian Foredeep depicted the Devonian and Carboniferous source rocks as the best source for hydrocarbon generation. Moreover, the Outer Carpathian sequence was geochemically characterized and proved capable of generating hydrocarbons. The oil-source rocks' correlations indicated that the source of the condensate accumulated in the Łąkta field, while oil in the Grobla field. Maturity modelling identified Devonian source rocks as they reached a late phase of the "oil window" and, locally, even the "gas window". The Carboniferous source rock was mature enough to start the generation processes. The generation started in the late Carboniferous, both in the Upper Silesian and Małopolska blocks. The main phase of the petroleum processes took place in late Neogene. The expulsion was observed only in the Devonian source rocks, and vertical migration by fault system in both blocks resulted in oil and gas accumulation in the Upper Jurassic carbonates and Upper Cretaceous sandstones. The petroleum modelling indicated the Devonian source for oil and gas fields in the study area. However oil-source rock correlation also suggests the presence of the Carpathian flysch source for hydrocarbons accumulated in the Łąkta field.
