Opis:: Four newly discovered moldavites from the East and West Gozdnica pits, SW Poland, are characterized. All specimens, including other four, reported earlier, are from Upper Miocene fluvial sediments of the Gozdnica Formation. Their weight varies between 0.529 and 1.196 g. The moldavites are bottle green in colour and have bubbles and inclusions of lechatelierite. Low degree of corrosion suggests short river transport, apparently eastward from Lusatia.

Opis:: High-resolution grain-size investigations were carried out in two SW Polish loess sections: Biały Kościół (Niemcza-Strzelin Hills) and Zaprężyn (Trzebnica Hills). Each sequence was sampled by using the same methodology and samples were taken at 5 centimeters intervals. The particle size distribution was obtained with a Mastersizer 2000 laser, used for diffraction methods. From the obtained results the basic parameters and grain size indicators were calculated: Mz, Grain Size Index ratio, U-ratio and the percentage content of clay (< 4μm) and sand (> 63 μm). Both loess- soil sequences are composed of interfluve and slope loess facies and consist of five litho-pedostratigraphic units developed during the Late Pleistocene and Holocene: two loess units L1LL1, L1LL2 and three polygenetic fossil soils sets S0, S1 and L1SS1. The distance between these two profiles is about 60 km. Zaprężyn, as a section located more to the north, has almost no lower younger loess and higher level of weathering which could be related to proximity of this site to the Ice Sheet margin. The climate here was more extreme and harsh. What is more,the difference in development of soil L1SS1 can be observed: while in Biały Kościół pedogenesis process was slower and less disturbed than in Zaprężyn. The upper part of L1SS1 in Biały Kościół was deformed by gelifluction, frost heave and other periglacial processes. Mz indicator by the grain-size distribution in these sediments reflects subtle variations in the climatic system. Moreover, in Zaprężyn the content of sand fraction is higher than in Biały Kościół what can be the evidence of short episodes of strong winds during cold period of sedimentation. The aim of this paper is to compare two loess profiles by their stratigraphical and lithological similarities which are result of climate conditions and features of surrounding environment.

Opis:: The development of basal Zechstein (Wuchiapingian) strata inSW Polandindicates the existence of a diversified relief inherited after the flooding of the pre-existing depression by the transgressing Zechstein sea. The deeper parts of the basin were the place of development of thin basinal Zechstein Limestone showing sedimentary condensation manifested by bored and encrusted grains and thick evaporites (mostly halite), and in shallow parts Zechstein Limestone reefs followed by thinner evaporite sequences (dominated by anhydrite) occur. The analysis of 3D seismic sections showed that instead of three conventionally recognized evaporite units of stratigraphic potential in the PZ1 cycle, five units occur (from the base to the top: Lower Anhydrite, Lower Oldest Halite, Middle Anhydrite, Upper Oldest Halite, Upper Anhydrite). In a particular place their number may vary from two (Lower Anhydrite at the base of the PZ1 cycle and Upper Anhydrite at the top of the PZ1 cycle) to five. There are two complexes of Lower Anhydrite occurring throughout the platform and basinal zones showing deepening-upward (transgressive) trend. The halite sedimentation in the deepest parts of salt basins began shortly after the deposition of the upper Lower Anhydrite complex while in the sulphate platform areas the sulphate deposition lasted still for a long time. The Lower Oldest Halite deposits occur in the depressions. Between the halite basins, anhydrite platforms occur, and the thickness of anhydrite platform deposits is smaller than it is observed in salt basins. The Upper Oldest Halite in turn is recorded above the anhydrite platform. The two halite units represent different phases of development of halite basins. The Lower Oldest Halite basins are related to the pre-Zechstein depressions, although in some cases their syndepositional subsidence was controlled by reactivation, during the deposition of basal Zechstein strata, of former faults. In turn, the Upper Oldest Halite basins used the accommodation space created due to anhydritization of the Lower Anhydrite deposits composed originally of selenitic gypsum. The 3D seismics evidences that the PZ1 evaporites inSW Polandhave been deposited in far more complex and dynamic system than it was assumed before.

Opis:: Mud-silt deposits of the Lower Jurassic Ciechocinek Formation from the Czestochowa-Wielun region are characterized by a low diversity ichnofossil association, which includes the ichnogenera Planolites, Palaeophycus, Helminthopsis, Gyrochorte, Protovirgularia and Spongeliomorpha as well as some unidentified pascichnia. This association points to deposition in a low-energy brackish environment with poorly oxygenated sediments. Changes of seafloor oxygenation, influenced by periodical bottom currents, resulted in various bioturbation intensities, which range from none to high.

Opis:: Many well preserved trace fossils were found in erratic boulders and the fossils preserved in them, occurring in the Pleistocene glacial deposits of the Fore-Sudetic Block (Mokrzeszów Quarry, Świebodzice outcrop). They include burrows (Arachnostega gastrochaenae, Balanoglossites isp., ?Balanoglossites isp., ?Chondrites isp., Diplocraterion isp., Phycodes isp., Planolites isp., ?Rosselia isp., Skolithos linearis, Thalassinoides isp., root traces) and borings ?Gastrochaenolites isp., Maeandropolydora isp., Oichnus isp., Osprioneides kampto, ?Palaeosabella isp., Talpina isp., Teredolites isp., Trypanites weisei, Trypanites isp., ?Trypanites isp., and an unidentified polychaete boring in corals. The boulders, Cambrian to Neogene (Miocene) in age, mainly came from Scandinavia and the Baltic region. The majority of the trace fossils come from the Ordovician Orthoceratite Limestone, which is exposed mainly in southern and central Sweden, western Russia and Estonia, and also in Norway (Oslo Region). The most interesting discovery in these deposits is the occurrence of Arachnostega gastrochaenae in the Ordovician trilobites (?Megistaspis sp. and Asaphus sp.), cephalopods and hyolithids. This is the first report of Arachnostega on a trilobite (?Megistaspis) from Sweden. So far, this ichnotaxon was described on trilobites from Baltoscandia only from the St. Petersburg region (Russia). Arachnostega on a trilobite (Asaphus), a cephalopod and hyolithids is from Russia or Estonia. Another interesting ichnotaxon is Balanoglossites, which also was encountered in the erratic boulders from the Ordovician Orthoceratite Limestone of Sweden. So far, this ichnotaxon was known only from Russia (St. Petersburg region). Some rare borings (e.g., Osprioneides kampto, ?Palaeosabella isp.) also were found in glacial erratics of Silurian stromatoporoids, excellent outcrops of which are located in Gotland (Sweden) and Saaremaa (Estonia). In addition, stromatoporoid/coral, coral/coral and some new fossil associations are reported. The material studied probably was transported from the N, the NE, and less commonly from the NW.

Opis:: Lower Silesia hosts important European nephrite deposits of Jordanów and less-known of Złoty Stok. Nephrite artifacts were discovered in archaeological sites dated back to the Neolithic period, across Eurasia. Especially artifacts found in Poland, Italy and Bulgaria may originate from Polish nephrites. Nowadays, only one artifact is precisely linked to Jordanów. Petrographic study of nephrites and chemical analyses of constituents by means of EMPA allow accurate identification of the nephrites. The characteristic phases of Jordanów tremolite nephrite are rotated and cataclased diopside porphyroblasts with pressure shadows, chlorite layers and nests with interlocking non-pseudomorphic texture and prehnite veins. The presence of hydrogrossular, grossular, titanite, apatite with monazite inclusions, and zircon with pleochroic haloe is typical. Chlorites are usually represented by penninite, and minor clinochlore and diabantite. The characteristic features of Złoty Stok actinolite nephrite are löllingite and diopside crystals usually visible by the naked eye, with the presence of quartz and carbonates. Löllingite is chemically inhomogeneous and gold bearing. Most of the mineralogical-petrological features can be obtained using non-destructive methods.

Opis:: Five Middle Triassic crinoid taxa: Eckicrinus radiatus (Schauroth, 1859), Holocrinus acutangulus (Meyer, 1847), H. dubius (Goldfuss, 1831), Dadocrinus sp. and Encrinidae gen. et sp. indet., from the North-Sudetic Basin, are described. The occurrence of Eckicrinus radiatus (Schauroth) is reported in the area for the first time. Based on the stratigraphic distribution of the crinoids, the ranges of three crinoid zones (Dadocrinus Zone, acutangulus Zone and dubius Zone) have been constrained. A modified correlation between the Lower Muschelkalk deposits of the North-Sudetic Basin, Upper Silesia and the Holy Cross Mountains is proposed.

Opis:: Fluorite mineralization was studied in the Variscan granitoid Karkonosze pluton in the northern part of the Bohemian massif (Lower Silesia, Poland). Fluid inclusions in fluorite and quartz were investigated by the following methods: heating and freezing on an immersion microscope stage, spectrophotometric and electron probe analysis, calcination and water leachate. The parent fluids of fluorite were of the Na-Ca-Cl type with a low CO₂ content. The fluoride ions had sources in the pluton and in its host rocks. Fluid inclusion observations provide evidence of various post-formation alteration. such as refilling, partition, cracking, migration, expulsion or vacuole modification from irregular to cubic habit. A final model of fluorite origin and parent fluid evolution is presented.

Opis:: Hydrophilic elements, such as sphenopsids and fems, are rare in the flora of the Krasiejów site and they are poorly preserved. One sphenopsid species, Neocalamites merianii, was recognised. It is preserved as impressions, flattened casts, moulds and isolated leaves. So far, only one small fern specimen, determined as Sphenopteris sp., has been found. These elements probably were transported to the site of deposition and did not grow where they were buried.

Tytuł:: Complementary data on the palynostratigraphy of the Carboniferous succession of SW Poland

Powiązania:: https://bibliotekanauki.pl/articles/2059084.pdf
Data publikacji:: 2010

Tematy:: Carboniferous

Variscan Foreland Basin
Opis:: New palynostratigraphical data concerning the Carboniferous sedimentary succession of SW Poland has been obtained from the Czerńczyce IG 1 borehole and the Brońsko boreholes on the northern slope of the Wolsztyn-Leszno High, where the oldest rocks were expected. The miospore assemblages recovered from the Czerńczyce IG 1 borehole allowed assignment of the interval studied to the Marsdenian (Namurian B) and Yeadonian (Namurian C). These results, supplemented with previous palynostratigraphical data, refute the existence of a stratigraphic gap between the early Namurian and Duckmantian (Westphalian B). The reinterpretation of the unpublished miospore results of Górecka et al. (2000b, 2001a) from the Carboniferous rocks from the Brońsko boreholes, also indicate that they should actually be assigned to the upper Marsdenian and Yeadonian. All analysed miospore assemblages are mixed and contain abundant reworked specimens. The results above complement previous opinions and permit a re-evaluation of the stratigraphy of the Carboniferous siliciclastic succession of SW Poland. Its sedimentation was certainly initiated in the earliest Namurian or earlier and probably lasted without long gaps until the Stephanian. The abundance and common occurence of reworked miospores indicate the age of rocks eroded during Carboniferous deposition. The lithological and palynofacial features of the late Namurian rocks from the Czerńczyce IG 1 borehole may be interpreted as a record of the shallowing of the sedimentary basin, including the possibility that some of the sedimentation occured in continental conditions. This means that the transition from the deep marine environment to shallow-water or even continental habitats likely had already taken place by the late Namurian. This suggestion, together with the tectonic deformation dated as post-Bolsovian, corresponds to the timing of the deposition and deformation in the German part of the Variscan Foreland Basin.
