Mires are common in the landscape of the Kraków-Częstochowa Upland, but they are rarely explored by Earth scientists. In addition to numerous morphological depressions filled with biogenic sediments, mires also occur within river valley, usually upstream from gaps. The intensification of marsh formation within the Białka River valley (left-side tributary of Krztynia, upper Pilica catchment) may have been influenced by the occurrence of poorly permeable, fluvial silty sands in the bedrock. Infilling of the studied depression at Młyny was accomplished via fluvial sedimentation characterised by local aggradation interrupted by carbonate precipitation, and sedentation of autochthonous organic matter. The former sediment type is represented mostly by mineral-organic aggraded silt with a dominant fine fraction, occurring mostly in the basal part of the studied core, and sand fraction in the top interval of the core, superjacent to calcareous-clay gyttja. Ash content reaches up to 87% and Fe concentrations are periodically elevated (30–48 mg/g). Calcium carbonate (CaCO3) also occurs in the studied oxbow mire deposit, exceeding 40% in some intervals, which indicates that a more important part was played by groundwaters in the water balance of the Białka valley. This periods were periodically interrupted due to higher flooding activity and recorded by mineral sediments characterised by specific granulometric composition, and an elevated percentage of organic matter deposited as rhythmists. Elevated concentrations of trace elements noted in a horizon dated at 1885±105 BP by means of radiocarbon dating may point to human impact on the environment due to the adaptation of economy to local conditions. The geochemical record of human activity is corroborated by archaeological data from various parts of the Białka valley catchment. The reason for the concentration of trace elements being highest in the top interval of the studied core is the intense economic development of Silesia-Kraków region, and the associated deforestation, mining and metallurgy.

This paper presents the results of a study on the content of lithogeochemical components (organic matter, Na, K, Mg, Ca, Mn, Fe, Cu and Zn) and grain-size composition of mineral matter in the bottom sediments of Morzycko Lake (Myślibórz Lakeland, NW Poland). This lake is large (342.7 ha) and deep (69 m). The catchment has a typical forested character (mainly in the middle part of the Słubia River valley) with agricultural area (mainly in the upland areas north of the lake). The diversity of concentrations of metals was analysed based on 44 samples from 22 representative sites, including surface sediments and sediments from 5 cm below the current lake bed. The results showed that the chemical composition and granulometry of bottom sediments depends on contemporary morphogenetic processes in the catchment of the Słubia River. Geochemical and grain-size indices varied due to changes in biological productivity, intensity of weathering of postglacial material making up the catchment, and potential for migration of metals to the lake with surface or underground runoff. An important aspect in assessing the degree of enrichment of the sediments in trace elements is the location of shallow parts of the lake near the tourist districts of Moryń.

The research area lies within the Old-Polish Industrial District (OPID), which functioned in recent centuries, where appropriate environmental conditions such as shallow iron-ore deposits, high forest cover and the availability of hydropower supplied by rivers contributed to the development of mining and metallurgy. This activity led to changes in valley floors and the river network that are visible on historical and contemporary cartographic materials, as well as in the relief and sediments of different origins. This work is a case study of a former waterbody at Furmanów in the Czarna Konecka River valley (Małopolska Upland), where the preliminary analysis of cartographic materials allowed to select the object for detailed research.

This paper presents the results of geochemical analysis performed for the more-than-10-m-long core of sediments derived from Lake Nowowarpieńskie. Contrary to what its geographical name would suggest, it is in fact a peripheral bay of the Szczecin Lagoon (NW Poland). A characteristic feature of the sedimentary cover of this water body is the several-metrethick layer of lacustrine chalk, which is unique in the lithology of the sediments of today's Szczecin Lagoon. This sediment has been analysed using atomic absorption spectrometry (AAS), energy-dispersive X-ray spectroscopy (EDS) and scanning electron microscopy (SEM) imaging. The chalk sediment from Lake Nowowarpieńskie is of chemical origin, bearing no fragments of vascular plants, but only traces of C-org in the form of small plant remains. The analysis of individual crystals using the EDS method also show Ca contents of over 99%. SEM images reveal that the sediment is characterised by a loose, disordered packing of individual crystals, often combined to form aggregates with a tabular structure. The individual calcite grains are usually a few micrometres in size, while developed ones are mostly hypidiomorphic and show signs of corrosion. The sedimentation of the lacustrine chalk indicates that the post-glacial natural development of this part of what today constitutes Szczecin Lagoon differed from that of the rest of the lagoon. This sediment was deposited in a shallow but fertile isolated lake. The full profile of sediments from Lake Nowowarpieńskie reveals its distinct bipartite character, indicating two main stages of its evolution: carbonate and post-carbonate. In the first, the water body showed similarities to the neighbouring lakes of the Wkrzańska Plain. Its evolution was driven by climatic factors. The second stage was initiated by a palaeohydrological factor – Littorina transgression, which resulted in the lake being included into the hydrological system of the Szczecin Lagoon.

The article discusses the impact of the relief and geological structure of a large river valley on the quality of material in two cores of organic deposits. The location of both sites was highlighted, the relief of the physicographical mesoregion in which the research was carried out and the geomorphology of the immediate surroundings of the sites were characterised, and geological conditions were discussed in more detail. Sequences of changes in Cladocera subfossil fauna at both sites were presented and the obtained record of their transformations was interpreted. Additionally, the results of analyses of five selected physicochemical parameters of the tested organic compositions were considered, and the obtained data were interpreted. It was concluded that the location of the studied cores in the valleys of large rivers had a significant impact on the quality of material analysed, which ultimately affects the certainty with which environmental changes and increasing human impact can be inferred and the reliability with which they can be reconstructed.

In the Serteyka River valley in western Russia, eight accumulative fans formed at the mouths of ravines were examined geologically and geomorphologically. The test samples were collected from individual geological drillings made with a manual probe, as well as from excavations in the central and distal zones of the fans. Using the Gradistat program, sedimentological indicators were calculated, i.e. mean grain diameter (MZ), standard deviation (sorting – σI), skewness (SkI) and kurtosis (KG),and then particle-size distribution frequency curves, cumulative curves and a Passega C/M diagram were drawn. It has been documented that the grain size of the fan sediments depends on the characteristics of the source material. Analysis of sedimentological indicators (mean grain diameter, sorting, skewness, kurtosis) showed the studied fans deposits to have a large variability of erosion and accumulation conditions. For the deposits of younger fans, the 2 system of the MZ-versus-σI relationship after MycielskaDowgiałło (1995) was distinguished, while for the older, the 2, 3 and 4 systems were recognised. The main process of grain transport within these forms was saltation. The ravines on the eastern slope of the Serteyka valley were most likely created in the periglacial period, while the gullies on the western side of the valley developed in the early modern period.

Identifying ancient shores may provide valuable information concerning sea-level fluctuations and environmental changes, since they serve as a reliable marker of palaeoshorelines. This paper deals with deposits that display features of a nearshore zone. In the Jurkowice-Budy quarry (southern slopes of the Holy Cross Mountains) a sequence of clastic sediments and littoral structures linked to the transgression of the Paratethys Sea in the middle Miocene has been recognised. The discovery of bio-erosional assemblages (borings of lithophags) in Devonian limestone boulders helped to determine the littoral nature of the examined deposits and to layout a palaeocliff wall. The samples of sandy sediments were analysed by sieving procedure and interpreted using statistical parameters calculated by graphic and moment methods. Moreover, morphometric analysis of gravels and analysis of mineralogical composition under binocular microscope were performed. The results showed well-developed beach assemblages composed of pebbles, coarse-to-medium sands and silty sands derived from eroded Cambrian strata (sandstones) located to the north of the study site.

The Low Volga basin is an important area for the study on the genesis of Neolithic and Eneolithic archaeological cultures in Eastern Europe. Until now well stratified Neolithic-Eneolithic sites had not been found in the Low Volga (Low Povoljie) region. This has been a cause of serious discussion about the periodisation, genesis and interaction between cultural groups during the Late Stone Age in this area. Excavations of new open sites of Algay and Oroshaemoe began in 2014. Both sites are unique for the Low Povoljie. It is important that the archaeological layers are within loess loam and they are interlayered with sterile natural layers. This fact precludes a mixing of artefacts of different ages. Most of the artefacts and ecofacts found in a clear stratigraphic context allow for a presentation of the detailed characteristics of the Orlovskaya Neolithic culture, and the Cis-Caspian and the Khvalynskaya Eneolithic cultures. For the first time, reliable data have been obtained for a periodisation of the Neolithic-Eneolithic of the Low Povoljie. A set of radiocarbon dates for all archaeological layers allows for a determination of the precise chronological frameworks of Neolithic-Eneolithic cultures in this region. The geochemical analysis of archaeological layers and sterile interlayers made possible a reconstruction of climatic characteristics for different periods of the Holocene. The processes of development of archaeological layers in the periods of the Orlovskaya and the Cis- -Caspian cultures were considered.
