Opis:
The first geological and engineering investments in Lublin related to the defense and the isolation of the castle can be dated back at least 700 years. Today, the oldest ones among them are documented only during archaeological excavations in the areas of hills/promontories in the eastern edge of loessic Na³êczów Plateau, steeply sloping down to the valley of Bystrzyca River. Over the centuries, the growing town, required number of investments conditioned by the geology (surface rocks) and relief. The city expanded to the areas of different in geology and topography. As a result of geotechnical works, implemented over several hundred years, modern Lublin is the town that could boast a number of multiage and diverse geotechnical objects. These are primarily objects designed to serve the defense, streamlining communication and also widely understood economy.

Opis:
In the Lublin region Carboniferous sandstones are represented by subarkosic, quartz and sublithic, occasionally arkosic arenites and wackes. These rocks are characterized by porosity (primary and secondary) ranging from 0 to 22.43% and permeability from 0 to over 1000 mD. Two diagenetic processes, that is compaction and cementation, were primarily responsible for reduction of porosity in these sandstones. The compaction decreased porosity at about 50%, while the cementation at 30%. Quartz, kaolinite and carbonates and locally fibrous illite are the most common cements here. Dissolution is also important as a diagenetic process responsible for development of secondary porosity. Good porosity of the bulk of Carboniferous sandstones is due to precipitation of early overgrowth cements (quartz, Fe-chlorite and siderite), which stopped the mechanical compaction, and dissolution of feldspar grains and authigenic quartz leading to origin of secondary porosity. The processes of mechanical compaction and advanced quartz and carbonate cementation (mainly of the ankerite and Fe-calcite type) as well as crystallization of fibrous illite were the major factors responsible for reduction of porosity in some sandstones. The results of the studies on pore space indicate good reservoir properties of sandstones of the Lublin and Dęblin formations as well as some parts of the Terebin formation. The sandstones from the Huczwa formation and a part of the Terebin formation belong to rocks characterized by low petrophysical parameters. Comparisons of sandstones formed in different environments have shown that best reservoir conditions are displayed by these formed in river channel and delta bottom ennvironments. During diagenesis, the Carboniferous deposits remained under influence of the maximum temperature of about 120oC, but locally the temperatures could have been even higher. Maximum temperatures were reached by the Carboniferous deposits at the end of Carboniferous whereas diagenetic proccesses were active until early Permian. The results of studies on diagenesis of these rocks, projected onto the thermal-erosional model, point to the Variscan overheating.

Opis:
In western and central parts of the Podlasie-Lublin Basin, Upper Ordovician-Lower Silurian mixed siliciclastic-carbonate section is dominated by fine-grained sediments (claystones, mudstones), which are passing into more carbonaceous ones towards the east. In this region, subsidence was controlled by flexural bending of the East European Craton margin. Sedimentological analysis of drill cores revealed that deposition of those fine-grained sediments originated from suspension and traction currents. Amount of oxygen plays important role in the rock record (Fig. 1) whereas occurrence of pyrite is significant for determinations of sedimentary conditionsion, also in terms of sea level changes (Fig. 2). The rocks display abundant sedimentological structures such as current ripples, wave ripples, hummocky cross-stratification (HCS), graded beds, water escape structures, soft sediment deformation and scours (Fig. 3). The rocks are also characterized by predominance of wave ripples, common scours, graded beds and soft sediment deformations whereas current ripples, water escape structures and HCS are rather rare. The most frequent of the ichnofacies elements include unlined, rarely branched Planolites, which represent Scolithos, Cruziana and Zoophycus ichnofacies. The size of elements of Planolites ichnofacies appears dependent on environmental conditions and ranges from 0.5 mm to 15 mm. Chondrites, Anconichnus, Helminthopsis and Teichichnus, very important environment indicators, are present but not that common (Fig. 4). Textural analyses along with the records of diagenetic features made it possible to distinguish a succession of stratigraphic parasequences (Fig. 5). Early carbonate cementation appeared important, especially in the case of suble or invisible changes in grain size. On the basis of the obtained results, depositional environment of fined-grained sediments in the Podlasie-Lublin Basin was interpreted as a wave-dominated shelf with turbidite episodes. Detailed sedimentological observations are crucial for definiting facies types and prediction of their distribution, but also for tracing the most organic-rich units in the sedimentological profile, as the basic in terms of gas shale prospects. Apparently monotonous fine-grained sediments (claystones and mudstones) are shown to be in fact miscellaneous.

Opis:
The characteristic group of loess relief in the western part of the Lublin Upland makes up a unique and varied landscape that is particularly attractive for tourists. Gullies, whose density exceeds 11 km/km2 in the Kazimierz Dolny area, are the best known element of the loess landscape. Along the gullies, tourist and interpretive trails have been established, but there is a lack of well-prepared geotourism trails. The southern part of the study area, the Urzędów Hills, is particularly underdeveloped in terms of tourism. This study presents the key characteristics of loess relief in the western part of the Lublin Upland, the current development of tourist infrastructure, and prospects for geotourism based on the unique landforms in the area. A few geotourism trails focusing on the unique loess relief features have been proposed, and attention has been drawn to threats to these landscape assets posed by certain forms of adventure tourism and problems related to private land ownership.

The Holy Cross Mountains Fold Belt, the Odrzywół–Ćmielów Graben, the Radom-Kraoenik Horst and the Mazovia-Lublin Graben are located in the contact zone between the Paleozoic Platform and the East European Craton, eastwards of the Variscan foreland basin. The Holy Cross Mountains Fold Belt consists of the Kielce and the Łysogóry Fold Zones. The boundary between the Kielce and Łysogóry Fold Zones is formed by the Holy Cross Fault. Southwestern border of the Kielce Fold Zone is probably consistent with the extent of the folds in the Małopolska Block. The Łysogóry Fold Zone is probably bordered from northeast by the Skrzynno Fault, which is also a boundary of the Radom-Kraoenik Horst from the southwest. The Radom-Kraoenik and the Mazovia-Lublin Graben are separated by the Kazimierz-Ursynów Fault. Northeastern border of the graben is the Kock Fault.

Opis:
In the present contribution we examine possible role of deposits of the Białopole, Lublin, Włodawa and Mazowsze Forma-tions (uppermost Ediacaran to lowermost Cambrian), as well as their presumed lateral equivalents, developed in the Lublin-Podlasie region as a potential source rock for hydrocarbons. The analysed sediments contain marine kerogen of algal and cyanobacterial ori-gin, i.e., predominantly oil prone. In some parts of the analysed area recent TOC could reach 0.65%, however, primary TOC could be significantly higher, as it is indicated by relatively high maturity of the hydrocarbons. Quality of potential source rock increases towards SW. The analysed potential source rock could be, at least partly, responsible for oil and gas shows, commonly observed in the Lower and Middle Cambrian sandstone horizons.

Opis:
The paper presents the results of analyzes executed within the project carried out by the Polish Geological Institute – National Research Institute. The purpose was to develop a density model of sedimentary cover in, inter alia, the Lublin region, on the basis of archival laboratory measurements. The source material consisted primarily of a database of archival measurements made on samples taken from drill cores. Since the sampling was often fragmentary and missed long intervals of the section, it was necessary to develop a methodology for estimating the density of such blank intervals. Trend equations of density changes with depth were determined on the basis of existing measurements, which helped in the estimation. For each stratigraphic period, density weighted average was calculated, where the thickness of each depth interval was the weight. Juxtaposition of such average densities with the arithmetic means, with or without taking into account the estimated values, indicates the pros and cons of the methodology. The final step was to construct the following: density maps of each stratigraphic period, maps of density contrast at the top-bottom contact of two stratigraphic periods and density maps at selected depth levels.

Opis:
The Durne Bagno peat bog is the eastern, peripheral part of a large marshland complex in the Lublin Polesie. Limnic biogenic deposits occurring directly on mineral deposits are up to 8.5 m thick. They exhibit great vertical facial variability and small lateral differentiation. This indicates that the conditions of sedimentation/sedentation were similar in the whole basin in particular time intervals. The chronostratigraphically-correlated sequence of sediments allows reconstruction of the geosystem evolution in recent 13 ka BP. In its entire Late Glacial and Holocene history two basic stages may be distinguished: lacustrine (OD — middle AT) and mire (middle AT — present time)

Opis:
The purpose of the study was petrographic-mineralogical analysis of volcaniclastic rocks occurring in the Lublin Basin, within the Kłodnica Member (Tournaisian, Visean), in seven boreholes. Its results were linked with the results of sedimentological and sequence stratigraphy studies to reconstruct the genesis of the sediments, as well as spatial and age relationships. Fine and coarse ash tuffs were identified, whose composition indicates acidic and alkaline volcanism. Accompanying volcaniclastic conglomerates and sandstones were formed mainly in the Tournaisian, before volcanic activity began. These sediments fill incised valleys, and belong to the oldest Carboniferous sedimentary filling of the Lublin Basin.

Opis:
The paper presents issues related to the changes of groundwater with drawal in Lublin in the 20th and 21st centuries and their consequences. The research has been based on the analysis of published and archival materials of the Department of Hydrology, Maria Curie Skłodowska University in Lublin, and the Municipal Water and Sewerage Company in Lublin. The collected data have allowed for the preparation of groundwater contour maps for several hydrodynamic situations in 1955-2015. Assessment of the range and depth of the depression cone in zones of water intakes and in the city in the last 70 years was determined by comparison of the present-day groundwater contour map and the map for 1955. High water withdrawal in the 1980-ties has resulted in lowering of the groundwater table. In the last decades, after the marketization of water prices and economic changes, decrease of water withdrawal took place, which in the case of higher precipitation resulted in increased groundwater levels.

Opis:
Petrological studies of core samples, integrated with mesostructural analysis of cores, and coupled with results of seismic data interpretation allowed to interpret evolving reservoir properties of dolostones of the Frasnian Werbkowice Mb. These crystalline and partly vuggy rocks form main reservoir horizons of the Ciecierzyn and Mełgiew A gas fields in the central Lublin Graben. The optimum reservoir properties were attained following the main phase of regional dolomitization and accompanying CaCO3 dissolution. These processes occurred after renewed subsidence in Viséan and before main phase of the Variscan inversion in late Westphalian. In Late Silesian, after the onset of hydrocarbon generation, porosity was partly filled by a dolomite cement. The most important agent of porosity destruction, however, was a precipitation of anhydrite cement preceding main phase of compressional deformations. The latter led to a localized development of open fracture systems which, however, were soon filled with various cements related to dissolution-reprecipitation processes. After compressional event, the stress regime evolved towards strike-slip and extensional, which created fractures allowing migration of hydrocarbons to newly formed structural traps. Several observed structures indicate negligible post- inversion deformations, thus facilitating preservation of earlier formed hydrocarbon accumulations. However, successive stages of secondary migration could have occurred during indefinite time under strike-slip and extensional regime recorded as a distinct set of mesostructures.

The paper presents the dynamics of the groundwater levels characterised in 2014 for 12 dug wells located in the border zone of Western Roztocze and the Lublin Upland. Data showing groundwater level fluctuations were obtained using automated pressure water level recorders installed in wells dug in 2013. Data used for characterisation of the meteorological conditions were provided by the weather station in Janów Lubelski; they comprised daily precipitation values, mean daily values of air temperature at a height of 2.0 m above the ground level, and mean daily values of soil temperature at a 0 m level. The analysis was based on the characteristics of each well in terms of their location and groundwater level fluctuations. The collected material was used in an attempt at verification and completion of assumptions presented by Malinowski (1974) and Janiec (1984) concerning the types of dynamics of groundwater levels characteristic for this region.

Opis:
Sequence stratigraphy approach has been applied for the Neoproterozoic to Cambrian sedimentary fill of the Lublin–Podlasie Basin; the main goal of the study is to discriminate between eustatic and tectonic control of the observed sequence development. The Neoproterozoic and Cambrian sedimentary fill of the Lublin–Podlasie Basin is subdivided here into two second-order depositional sequences, separated by a basin-wide unconformity. The lower sequence A is poorly recognised. It is presumably of the early Neoproterozoic age, and is characterized by continental to costal shallow marine developments. Sequence B comprises the (late?) Neoproterozoic to Middle Cambrian. The lowermost part of the sequence B is composed of a lowstand systems tract (LST). At that time a low relative sea level was con-trolled by regional thermal doming, followed by rapid clastic and volcanogenic deposition, with rate exceeding that of subsidence of extensional grabens. During the latest Ediacaran, a transgressive systems tract I (TST I) developed. Increase of the rate of relative sea level rise was induced by a transition from syn-rift to post-rift subsidence. During the development of a following highstand systems tract I (HST I), significant sediment supply exceeded the rate of basement subsidence, causing progradation of shoreline. The next higher up-section transgressive system tract (TST II) is characterized by a gradual rela-tive sea level increase and reflects continued thermal sag phase of the Lublin–Podlasie Basin. Development of the TST II was coeval with a global transgression and controlled mainly by eustatic sea level rise. The beginning of the Middle Cambrian corresponds to the development of a HST II, controlled by a low rate of increase of the relative sea level, even if it was coeval in time with the Hawke Bay regression. The HST II is therefore interpreted here as controlled by local tectonic processes, superimposed on continued post-rift thermal subsidence of the passive margin.

Opis:
In the northern Lublin region, the Eocene amber-bearing association has been recognized. It is a group of clastic deposits in which amber crumbs are scattered, and the characteristic feature of the association is the content of glauconite. The sedimentological and lithofacies studies allowed determining the conditions necessary for amber deposition. Accumulation of amber-bearing sediments took place in the Middle and Late Eocene. The Upper Eocene formations in this area occur in isolated patches. Amber accumulations are found in marine sediments associated with regressive facies, usually in depressions of the Cretaceous basement. Understanding the correct distribution of amber in the sediment and determining the dynamics of the Eocene sedimentary basin in the Lublin region have a practical aspect, and are the basis for developing the characteristics of the geological economic conditions for the occurrence of amber-bearing deposits. The recently drilled boreholes confirmed amber resource prospectivity in the Lubartów area and the recognition of new deposits with amber reserves.

The paper presents results of geochemical analyses of organic matter (OM) in a tonstein bed and surrounding bituminous coal from the Upper Carboniferous (Westphalian B) coal seam no. 385/2 from the Bogdanka mine, Lublin Coal Basin. In all studied samples, including those of tonstein and bituminous coal, OM was found to be very similar in composition. Distribution of hydrocarbons in investigated rocks is characterized by strong predominance with odd-number carbon-atom of the long-chain n-alkanes in comparison to the even-number and high concentration of C29 steranes, what implies relatively high input of higher-plant OM in these samples. Minor concentration of C28 steranes and perylene points at presence of fungi. In all extracts, the tri- and tetracyclic diterpanes co-occur with their aromatized derivatives, what suggests presence of the tap resin species - precursors of the conifer families in the plant community. The abundance of sesquiterpanes, pentacyclic triterpanes and benzohopanes indicates a significant bacterial input, most possibly connected with bacterial activity after deposition of terrestrial OM. The original material of tonstein was pyroclastic in orgin, and deposited directly on plants living at the surface of a mire. That material hadn’t had any direct influence on chemicalOMtransformation. The biomarker data, both for coals and tonstein, reveals that sedimentary organic matter was heated up to a temperature corresponding to the level of immature/start of oil window. On the other hand, the increase in thermal maturity value, based on distribution of the aromatic hydrocarbons in organic matter in tonstein (theoretical vitrinite values - Rc, Rcs) are probably due to the presence of incompletely burned organic remains (charcoals), transported to the sedimentary basin along with volcanic ashes.
