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:
This study estimates the reservoir properties of the Carboniferous deposits in the southeastern part of the Lublin Basin based on diagenetic and sequence stratigraphic patterns. Depositional sequences distinguished represent the following environments/processes: shallow clay and carbonate shelves, deltaic, fluvial, and hyperconcentrated flow while para-sequences (cyclothems), maximum regression-initial transgression surfaces (T), maximum flooding surfaces (MFS) and also lowstand (LST), transgressive (TST) and highstand (HST) systems tracts have been recognised. Sequences recognized may be linked to the global stratigraphic division of the Carboniferous, thus providing a time framework and environmental context for petrographic and petrophysical examinations. The reservoir properties were found to be clearly controlled by depositional environment, diagenetic history and burial. The best properties were recognized in sandstone lithosomes formed in braided, meandering and anastomosed fluvial channels and hyperconcentrated flows which fill the incised valleys and belong to the LST. They are characterized by good porosity reaching up to 15.1%. The TST and HST deposits are represented chiefly by claystones, mudstones and limestones that formed in a shallow shelf and deltaic environment, being sealing intervals. The diagenetic history of sandstones comprises eo-, meso- and telodiagenetic phases. The major processes acting during the first of these were mechanical compaction, dissolution of mineral grains, formation of predominantly quartz overgrowths around the quartz grains, and crysialiizaton of kaolinite. During mesodiagenesis, cementation with quartz, kaolinite and carbonates continued along with the formation of dickite and fibrous illite; moreover, mineral grains were dissolved and chemical compaction set in. The effects of telodiagenetic processes were feldspar dissolution and precipitation of kaolinite. During diagenesis the maximum temperature affecting the Carboniferous deposits was ~120°C. Compaction and cementation were the main factors responsible for the reduction of porosity by approximately 55 and 38%, respectively. One of the major diagenetic processes was dissolution resulting in the formation of secondary porosity. The Serpukhovian and Bashkirian sandstones from sequence 11 show good reservoir potential, while those from sequences 6, 9, 10, 12-14 only fair potential.

Opis:
The main aim of this study is to define precisely the age of the alkaline basalts occurring within the lowermost part of Carboniferous succession in the northeastern part of LublinBasin(drill core Parczew IG-7 and IG-9; SE Poland). The new, whole-rocks 40Ar/39Ar data constrain the age of volcanic activity and emplacement of alkaline basalts to the Late Tournaisian (348 ± 0.8 Ma) with possible prolongation to the Middle Visean (338.5 ± 0.7 Ma). The younger age is however of evidently poorer quality than the older one. The new data caused to correlate the volcanic processes occurring within the Lublin Basin with alkaline intrusions drilled inNE Poland inside the Paleozoic cover of the East European Platform. They also correspond to the volcanoclastic levels defined in different parts of the Trans European Suture Zone in Poland.

Opis:
The uppermost Westphalian marine horizon (Dunbarella horizon) is especially important for correlation of Carboniferous deposits in the Lublin Coal Basin and in other basins of the Northwest European Carboniferous Basin. The Dunbarella horizon is characterized by cyclic sedimentation and consequent faunal spectrum variability, typical for Westphalian marine horizons of northwestern Europe. Palaeontological study of the Dunbarella horizon showed the presence of macrofauna representing different palaeoenvironments, from marine to brackish (non-marine) and freshwater conditions. The vertical sea level fluctuations and changes in seawater salinity resulting in palaeontological record changes do not link with geochemical proxies. TOC, redox-sensitive trace element concentrations, and V/Cr, Ni/Co and V/(V + Ni) ratios generally suggest that the Dunbarella horizon sediments were deposited under predominantly oxic conditions (with local exceptions during the initial phase of the Dunbarella ingression; Kopina 1 borehole).

Opis:
Detailed conodont data were obtained from 66 samples in 9 deep wells representative of three palaeogeographic regions of the Mid Devonian epicontinental basin of southeastern Poland: (1) the elevated part of the East European Platform representing the basin margin, (2) the Lublin Graben with a larger proportion of open marine systems, (3) the Radom Area characterized by more off shore, purely marine deposition and larger subsidence rates in the Radom Area. The 1344 specimens collected were as signed to 8 genera: Icriodus, Polygnathus, Ancyrodella, Belodella, Mehlina, Neopanderodus, Pandorinellina and Skeletognathus, and 38 taxa of species or subspecies rank. The vertical distribution of the conodont as semblages studied in particu ar sections is highly irregular and discontinuous with many barren intervals con rolled by less suitable palaeocological conditions, mostly representing restricted and/or very shallow-water facies. We found only a single index species characteristic of deeper marine facies, as applied in the standard conodont zonation. There -fore the biostratigraphic interpretation also takes into account the total range of all taxa found in particular samples, established after acritical analysis of adequately published total ranges of these taxa. The stratigraphicranges of the following taxa were modified: Icriodus arkonensis arkonensis, I. a. walliserianus, I. eslaensis, I. platyobliquimarginatus, I. subterminus, I. aff. I. subterminus, Polygnathus ansatus, P. latifossatus, P. linguiformis linguiformis, P. timorensis and P. varcus. As a result of the stratigraphic analysis of the conodon't assemblages we distin guished five zones in the Givetian of the studied area, i.e. the rhenanus/varcus, ansatus, hermanni, norrisi (=lower part of Lower falsiovalis Zone) zones, and also two in formal units, the subterminus and insita fau nas. We documented the co-occurrence of I. subterminus and P. latifossatus which supports the earlier supposition of Rogers (1998) that the Lower subterminus Fauna may partly corre pond to the Lower hermanni Zone.

Kock Fault Zone

Opis:
Integrated tectonic interpretation of seismic data and core samples from boreholes in the vicinity of the Kock Fault Zone (KFZ) allowed us to identify several tectonic deformation events that were responsible for creating its complex structure. The KFZ is an example of a mechanically weak regional-scale tectonic structure that accumulated deformation over hundreds of millions of years and therefore is a good indicator of stress regime changes in a broader area. The KFZ is here regarded as a combination and superposition of two genetically and temporally different faults: the older Kock Fault, which is an inverted normal fault, and the younger, low-angle Kock Thrust. The first, Silurian stage of KFZ evolution occurred in a tensional stress regime that gave rise to the activation of a deeply rooted normal-slip precursor to the Kock Fault. Subsequently, this fault underwent inversion during the Late Famennian compressive/transpressive event. In the Early Carboniferous, the tectonic stress regime changed into tension/transtension, leading to extrusion of basalt magma and abundant mineralisation in the vicinity of the inverted Kock Fault, followed by tectonically relaxed sedimentation of Carboniferous strata. The deposition was terminated by a compressional event at the end of the Westphalian. Contraction resulted in the formation of the low-angle Kock Thrust decoupled in Silurian shale that cut across the upper part of the Kock Fault and displaced it towards the NE, over the East European Craton foreland.

Opis:
The Rock-Eval source rock characteristics, mineral composition and type-porosity of reservoir horizons, and origin of natural gas in the Devonian of the Lublin and Lviv basins are described. In the Lower Devonian, the TOC content ranges from 0.01 to 1.82 wt.% in the Lublin Basin, and from 0.01 to 0.45 wt.% in the Lviv Basin. Transformation of organic matter varies from immature in the Lochkovian (Lviv Basin) to mature and overmature in the Emsian (Lublin Basin). The organic matter contains mainly Type-II kerogen, and underwent primary and/or secondary oxidation processes. In the Middle Devonian, the TOC content varies from 0.00 to 1.63 wt.% in the Lublin Basin, and from 0.02 to 0.64 to 2.35 wt.% in the Lviv Basin. The organic matter contains mainly Type-II kerogen and is immature in the Givetian of the Lviv Basin and mature in the Eifelian of the Lviv Basin and in the Eifelian and Givetian in the Lublin Basin. In the Upper Devonian, the TOC content is from 0.02 to 2.62 wt.% in the Lublin Basin, and from 0.04 to 1.43 wt.% in the Lviv Basin. Type-II kerogen dominates in both basins. Organic matter is mature in the Upper Devonian in the Lublin Basin and in the Famennian of the Lviv Basin and overmature in the Frasnian of the Lviv Basin. The reservoir horizons in the Devonian of the Lublin and Lviv basins are developed in clastic, carbonate and sulphate rocks. Terrigenous rocks form several separate horizons in the Lower and Middle Devonian of the Lviv Basin, and in the Upper Devonian (Famennian) of the Lublin Basin. Their filtration properties relate to intergranular porosity, while the fracture space has subordinate significance. Carbonate rocks form thick saturated horizons in the Givetian in the Lviv Basin, and in the Eifelian, Givetian and Frasnian in the Lublin Basin. Their filtration properties are produced by fracture porosity. Sulphates and carbonate-sulphate rocks with fracture and cavern porosity play a role as reservoir horizons in the Middle Devonian of the Lublin Basin. The natural gas collected from the Upper Devonian of the Lublin Basin was generated mainly during low-temperature thermogenic processes, from Ordovician–Silurian Type-II kerogen. The gas from the Middle Devonian reservoirs of the Lviv Basin was produced from Ordovician–Silurian Type-II kerogen and partly from the Middle and Upper Devonian mixed Type-III/II kerogen with maturity from about 0.9 to 1.4%. Carbon dioxide was formed by both thermogenic and microbial processes. Molecular nitrogen was generated mainly through thermal transformation of organic matter and also from destruction of NH4-rich illite of the clayey facies of the Ordovician–Silurian strata.

Opis:
In the Baltic-Podlasie-Lublin Basin, four potential lower Paleozoic shale reservoirs are identified: the Piaśnica, Sasino and Jantar formations, as well as the Mingajny shale. These units were diachronously deposited during the starved stages of Caledonian foredeep basin development, in the course of rising or high eustatic sea level. Across most of the basin, the shale formations analysed are saturated with light oil and condensate, and they are buried to depths of 2300-3500 m. The shale reservoirs reach the wet gas window at burial depths of 2800-4000 m, while dry gas accumulations occur at depths exceeding 3500-5000 m, except in the Biłgoraj-Narol Zone. The shale analysed might be generally classified as a moderate to low quality, and locally high quality, unconventional reservoir. Within the shale net pay zones, the average TOC content is 2-5 wt.% TOC. The exceptions are the Piaśnica Formation, for which this is 5-12 wt.%, and the Mingajny shale, which is TOC-lean (1.4-1.7 wt.%). The thickness of the shale net pay intervals in the most favourable locations, mainly on the Łeba Elevation, generally reaches 20 m, and locally exceeds 35 m. The shale reservoirs are saturated with hydrocarbons of good quality. Their permeability is low to moderate, often in the range of 150-200 mD, while total porosity average per borehole is commonly exceeds 6 %, reaching up to 10% at maximum, which might be considered as moderate to good. The clay minerals content is moderate to high (30-50%), and geomechanical characteristics of the shale formations are intermediate between brittle and ductile. No overpressure occurs in the basin, except for a dry gas zone in the SW Baltic Basin. In the Biłgoraj-Narol Zone, and to a lesser degree also in the Lublin region, pronounced tectonic deformation significantly limits shale gas/oil potential. Among 66 exploration boreholes drilled in the basin so far, only 5 were lateral boreholes with representative production test results. Hydrocarbon flow from the best boreholes was low to moderate, equal to 11.2 to 15.6 thousand m3/day for gas, and 157 bbl/day (~21.4 ton/day) for oil. There is, however, high potential to improve production flow rates, connected with the fracturing of two net pay intervals at one time, as well as with significant technological progress in the exploitation of shale basins during the last 5 years. Commercially viable production might be achieved for a single borehole with estimated ultimate recovery exceeding 30-50 thousand tons of oil, or 60-90 million m3 of gas.

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.

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.

Opis:
The Carboniferous sandstone of the Dęblin Formation is one of the targets for the petroleum industry in the Lublin Basin in southeastern Poland. The formation's primary and diagenetic composition makes it difficult to estimate its reservoir properties. Based on a detailed analysis of core and petrographic samples, normalization of gamma-ray and density logs was made with respect to the grain-framework of the rock. Recounted logs were used for distinguishing 4 different sandstone petrofacies. For these petrofacies, ranges of gamma-ray and bulk density values were determined and the impact of primary and diagenetic mineral composition was estimated. The application of this petrofacies method can upgrade the level of reservoir characterization and support the interpretation of uncored intervals.

Minerały ilaste należą do głównych składników spoiwa piaskowców karbonu w basenie lubelskim. Wśród nich wyróżniono minerały allogeniczne wchodzące w skład matriksu oraz minerały autigeniczne tworzące cementy. W pracy wykorzystano następujące metody badawcze: mikroskop polaryzacyjny, katodoluminescencję, skaningowy mikroskop elektronowy, analizę rentgenograficzną, badania spektroskopowe w podczerwieni oraz oznaczenia izotopowe wieku K/Ar diagenetycznego illitu. Głównymi autigenicznymi minerałami ilastymi w piaskowcach karbonu są minerały podgrupy kaolinitu – robakowaty kaolinit oraz blokowe: kaolinit i dickit. W mniejszej ilości występują: illit włóknisty, chloryty oraz minerał mieszanopakietowy illit/smektyt. W eodiagenezie krystalizowały kaolinit robakowaty i chloryty w obwódkach. W mezodiagenezie w temperaturze powyżej 50°C tworzyły się blokowy kaolinit i dickit, minerał mieszanopakietowy illit/smektyt oraz illit włóknisty. Transformacja kaolinitu w dickit wskazuje na temperaturę około 120°C. Oznaczenie wieku K-Ar krystalizacji diagenetycznego illitu – około 260 mln lat – sugeruje, że osady karbonu osiągnęły maksymalne temperatury około 160°C we wczesnym permie.

The following research methods were used in the paper: polarizing microscope, cathodoluminescence, scanning electron microscope, X-ray diffraction analyses, infrared studies and isotopic age K-Ar of diagenetic illite. The main authigenic clay minerals in the Carboniferous sandstones are kaolinite subgroup minerals – vermiform kaolinite and blocky kaolinite and dickite. In a smaller amounts are: fibrous illite, chlorites and illite/smectite mixed-layered mineral. Vermiform kaolinite and chlorite rims were crystallized in eodiagenesis. Blocky kaolinite and dickite, illite/smectite mixed-layered minerals and fibrous illite were formed above 50°C in mezodiagenesis. The transformation of kaolinite to dickite indicates the temperature at about 120°C. Determination of the K-Ar age of crystallization of the diagenetic illite – about 260 My ago suggests that the Carboniferous deposits have reached the maximum temperature of about 160°C in the Early Permian.

Opis:
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.

potential source rock for hydrocarbons
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.
