“…Therefore, the palaeoenvironmental assessment of the analysed section is derived from the following distribution trends shown by different phytoclast types, namely: (1) the high proportion of equidimensional, Palynology and sedimentology of the Mississippian at Tisdafine rounded and small opaque phytoclasts mainly suggesting a distal marine depositional environment as they result from a lengthy transport; contrastingly lath-shaped, large opaque phytoclasts are indicative of the short transport of these organic particles and support a proximal depositional environment (Radmacher et al, 2020); (2) the high relative frequency of translucent phytoclasts (cuticles, woody tissues), sometimes large in size, in ancient deposits suggests a strong terrestrial influx and proximal/near-shore depositional conditions (Tyson, 1995). Moreover, the size analysis of opaque phytoclasts can be used to assess their transport distances from the shoreline (Jurkowska & Barski, 2017;Tyson & Follows, 2000). Therefore, the measurements of equidimensional opaque phytoclasts have been performed using ImageJ software.…”

The Mississippian (Tournaisian–Visean) of the Jbel Asdaf area in the Tisdafine Basin (Eastern Anti-Atlas, Morocco) has been, for the first time, the subject of a palynological study. This work aims first to describe the lithological and the paleontological composition of the Aït Yalla and Tinerhir Formations, then to refine the age, reconstruct the paleoenvironment and assess the thermal maturity of the organic matter. The studied section is subdivided, from oldest to youngest, into three intervals, according to their lithological and paleontological compositions. Lithologically, the lower interval (lower part of the Aït Yalla Formation) and middle interval (upper part of the Aït Yalla Formation and basal part of the Tinerhir Formation) consist mostly of clay shales and green shales, respectively, both alternating with limestone or sandstone beds. The upper interval (upper part of the Tinerhir Formation) is dominated by sandstones, also alternating with pelitic-sandstone or limestone beds. The kerogen delivered by the analyzed samples is mostly of continental origin, composed mainly of opaque phytoclasts, while translucent phytoclasts and miospores are less represented. Marine fraction, consisting mainly of granular amorphous organic matter and some phytoplankton, are rare. Biostratigraphically, the late Visean Tripartites vetustus–Rotaspora fracta (VF) miospore Zone of the Western Europe biozonal scheme is recognized with some regards in the Tinerhir Formation, based on the first occurrence of the miospore Rotaspora cf. knoxi. Vallatisporites aff. ciliaris is another biostratigraphic marker taxon of the assemblage, whose the last occurrence marks the end of the VF Biozone at the top of the analyzed section. Qualitative and quantitative parameters of the different palynofacies constituents (e.g., shape, size, % of opaque and translucent phytoclasts) show, from the base to the top of the section, a gradual transition from a distal marine environment generally recognized in the Aït Yalla Formation towards an intermediate marine environment in the Tinerhir Formation, suggesting a sea-level fall. Optical analyses performed on the color of palynomorphs, mainly spores, suggest a thermal maturity, ranging from late mature to early post-mature stage for most of the analysed samples, with a burial depth and a temperature of at least 3300 m and 90 °C, respectively.

Theonellid and phymaraphiniid sponges were described for the first time in assemblages of Campanian lithistid Demospongiae collected from Miocene gravels in the Bełchatów lignite mine (Mogilno‐Łódź Synclinorium, central Poland). Here we add an analysis of sponges from museum collections, as well as of newly collected material from Campanian strata in the Miechów Synclinorium. Four phymaraphiniid and 11 theonellid species have been distinguished in these assemblages. Two phymaraphiniid species (Phymaraphinia infundibuliformis and Prokaliapsis janus), and five theonellids (Rhagadinia doederleini, Rhoptrum scytaliforme, Astrocladia laevis, Colossolacis plicata and Phyllodermia antiqua) have not been recorded previously from the Campanian of Poland. With three exceptions, all other theonellids and phymaraphiniids described herein are also known from the Campanian of Subhercynian and/or Lower Saxony basins in Germany. On account of the good preservation of the sponge skeletons, new data on the choanosomal and ectosomal spicules of Cretaceous theonellids and phymaraphiniids can now be presented. Our analysis of the distribution of theonellids and phymaraphiniids in various Cretaceous facies has allowed palaeoenvironmental factors conducive to the settlement of these sponges to be outlined.

Abstract. The Danish-Polish Trough – a large Trans-European sedimentary basin stretching from Denmark, through Germany, to south-eastern Poland and even further to the south into Ukraine, had undergone an uplift during the Late Cretaceous, which in consequence resulted in its inversion and development into the Mid-Polish Anticlinorium. In many existing paleotectonic interpretations, SE Poland, i.e. the subsurface San Anticlinorium and the recent-day Roztocze Hills area was included during the Late Cretaceous into the Danish-Polish Trough, representing its axial and most subsiding part. Such a paleotectonic model was the basis for facies and bathymetric interpretations, assuming that upper Cretaceous sediments deposited close to the axial part of the Danish-Polish Trough (e.g. Roztocze) were represented by the deepest facies. Several studies performed in recent years contradict this concept. The growing amount of data indicates that already from the Coniacian-Santonian times, this area was a land-mass rather than the deepest part of the basin – the same is true for the Campanian and Maastrichtian times. Additionally, recent discoveries of cyclic middle Campanian deposits of shallow deltaic origin, along with a decreasing contribution of terrigenous material towards the NE, have led to the adoption of new facies and bathymetric models, being all in opposite to most of the previous interpretations. The new interpretation implies the presence of a land-mass area in the place where formerly the deepest and most subsiding part of the Danish-Polish Trough was located. Here we document in detail the Late Cretaceous deltaic system, i.e. the Szozdy delta developed in the axial part of the Danish-Polish Trough. The middle Campanian deposits which crop out extensively in the middle Roztocze Hills region, close to the village of the Szozdy, exhibits coarsening-upward tripartite cyclothems. The sequence was deposited in a shallow-water, delta front platform setting. Three facies associations have been distinguished: (1) dark grey calcareous mudstone, deposited in prodelta environment, (2) yellow calcareous sandstone unit, interpreted as prograding delta front lobe deposits of fluvially-dominated though wave/tidally influenced setting, and (3) calcareous gaize unit deposited in areas cut-off from the material supply. The sequence as a whole was accumulated by repeated progradation and abandonment of deltaic complexes. This interpretation is supported by the new sedimentological, palynofacies, and heavy mineral data. The latter is also discussed in the context of their possible source rock provenance, which might suggest a different burial history than thought so far. The development of the Szozdy delta system is placed next to dynamic tectonic processes operating at that time in SE Poland, i.e. the inversion on the one hand, and the generation of new accommodation space for the deltaic deposits by enhanced subsidence. This discovery shed new light on our understanding of facies distribution, bathymetry, paleogeography, and paleotectonic evolution of the south-easternmost part of the inverting Danish-Polish Trough into the Mid-Polish Anticlinorium during the Late Cretaceous times.
