Marine transgression(s) to evaporite basin:The case of middle Miocene (Badenian) gypsum in the Central Paratethys, SE Poland

Journal of Palaeogeography 2020年第3期9卷 335-352页

作者： Danuta peryt Przemyslaw Gedl Tadeusz Marek peryt Institute of Paleobiology Polish Academy of SciencesTwarda 51/5500-818 WarszawaPoland institute of Geological Sciences Polish Academy of SciencesResearch Centre in CracowSenacka 131-002 KrakowPoland Polish Geological Institute-National Research Institute Rakowiecka 400-975 WarszawaPoland

The middle Miocene Badenian evaporite basin of the Carpathian Foredeep Basin was a saline lake, separated by a barrier from the sea and supplied with seawater seeping through the barrier or overflowing it occasionally in the form of short-lived marine transgressions. Such transgressions could leave behind marine microfossils in marly clay intercalations. One of them(2.3 m thick) occurs in the uppermost part of the sulphate sequence, in the unit ‘o’, in the Babczyn 2 borehole section. It contains marine palynomorphs(dinoflagellate cysts) and foraminiferal assemblages indicating a marine environment. The low-diversity benthic foraminiferal assemblages are dominated by opportunistic, shallow infaunally living species, preferring muddy or clayey substrate for thriving, brackish to normal marine salinity, and inner shelf environment. Dinoflagellate cyst assemblages, although taxonomically impoverished, consist of marine species;euryhaline forms that tolerate increased salinity are missing. Relatively common microfossils found in clay intercalations within gypsum have important palaeogeographical implications:they strongly suggest that there existed an additional inflow channel supplying the Polish Carpathian Basin from the south during the evaporite deposition and afterwards.

Palaeogeographical zonation of gypsum facies:Middle Miocene Badenian of Central Paratethys (Carpathian Foredeep in Europe)

作者： Tadeusz Marek peryt Polish Geological Institute National Research Institute

Studies on Middle Miocene Badenian gypsum in various parts of Central Paratethys,the oldest widespread primary marine gypsum,in western Ukraine,southern Poland and Moravia (Czech Republic) indicate that there are three principal gypsum facies:crystalline gypsum,stromatolitic gypsum and clastic *** latter typically occurs between crystalline and stromatolitic gypsum and between stromatolitic gypsum and the *** addition,it is common in channels within gypsum microbialites,and is the main facies during the deposition of the upper part of Badenian gypsum when important bathymetric differences existed within the marginal part of the Carpathian Foredeep Basin,the largest foredeep basin in *** crystalline gypsum facies,it is observed the overall size of the crystals increases and that the layering declines towards the permanent,stabilized brine body,and thus the giant gypsum intergrowths-non-layered coarse-crystalline selenite is the end-member of gypsum facies *** it passes into layered selenites although owing to fluctuations of pycnocline level,some transitional gypsum subfacies may be missing both in the vertical section as well as in particular *** following important controls on the development of gypsum facies have been identified:pycnocline level fluctuations,brine level fluctuations including brine sheets and floods,rare marine transgressions,pedogenesis leading to "alabastrine" gypsum development,and rate of inflow of continental water.

Sedimentary and environmental history of the Late Permian Bonikowo Reef(Zechstein Limestone, wuchiapingian), western Poland

Journal of Palaeogeography 2017年第3期6卷 183-205页

The Bonikowo Reef occurs in the central part of the Zechstein Limestone Basin in western Poland and was growing on the topmost edges of tilted blocks and/or on the top of uplifted horsts of the BrandenburgewolsztynePogorzela High. Its size is ca. 1.6 km^2. The Bonikowo Reef shows the thickest reef section（90.5 m） recorded in the High. The Zechstein Limestone unit is represented mostly by limestones, often thoroughly recrystallized, although the macrotextures and biota of the boundstone are identifiable in most cases. The drillcore section is a mixture of boundstones（microbial and bryozoan）, wackestones, packstones and grainstones, which often co-occur. The δ^13 C and δ^18 O values for both calcite（avg. 3.8 ± 0.8‰ and-3.4 ± 1.7‰, respectively） and dolomite（avg. 3.5 ± 0.7‰ and-5.2 ± 1.3‰, respectively） are transitional between the values previously reported for condensed sequences of the basinal facies and larger reef complexes. The biofacies of the Bonikowo Reef are very similar to those recognized in other reefs of the BrandenburgewolsztynePogorzela High, which owe their origin to the destruction of bryozoan boundstones. The biota composition is typical and characteristic of other Zechstein Limestone reefs. However, the Bonikowo Reef demonstrates the importance of microbialites, laminar and nodose encrustations, in the growth and cohesion of the Zechstein Limestone reefs. Such encrustations abound within the Zechstein Limestone although, in many cases, the real nature of the encrustations is difficult to ascertain. These laminated encrustations show great similarity to Archaeolithoporella that is one of the most important Permian reefbuilding organisms. The encrustations considered to represent Archaeolithoporella were also previously recorded in the Zechstein Limestone of western Poland and in its stratigraphic equivalent, the Middle Magnesian Limestone of Northeast England. The lower part of the sequence shows great biofacies variability that reflects common envir

波兰北部蔡希施坦统(P_2)主白云石碳酸盐的白云石化作用发生在准同生和(或)早期成岩作用阶段。盆地相白云石有序性良好且具有化学计量,而这里的台地型白云石有序性很差且通常不具化学计量。所采集的大多数样品与其它蔡希施统碳酸盐一样也高度富集^(13)C。δO^(18)值变化范围很大,从—511‰～+7.4‰所分析的白云岩具有同位素分带性。同位素特征值表明,白云岩形成于大气水、海水知可能的海成或陆成的蒸发卤水。一旦白云石化作用发生,其反应进程就与白云石化卤水的成分演化无关了。卤水的演化能用以解释泻湖白云岩的产出状态,即其剖面上部发育有良好的六面体晶形,而剖面的下部白云石已明显溶解。结晶分带表明白云岩最初是在超盐度的水中生长,这种超盐度水逐渐被淡水稀释。有同位素证据表明大陆水曾迁入盆地,其时间为主白云岩沉积末期的海平面下降时期。淡水对同沉积白云石化作用的影响,在主白云岩中表现十分明显,其它与蒸发岩有关的白云岩可能会有类似的特征。
