The thermal and mineralized waters in the subsurface of Sulejówek, Józefów, and Otwock towns of the Warsaw region have been analyzed. An initial assessment of the utilization of such waters based on deep boreholes and significance of these waters for development of the communities has been considered. The analysis shows that in the area of Sulejówek, Józefów and Otwock communes there are chloride and sodium waters in the aquifer of the Lower Cretaceous and the Jurassic of mineralization from about 10 to over 70 g/dm3, probably characterized by an increased content of specific components desirable in the case of waters used in balneotherapy – iodides (above 1 mg/dm3 in the lower cretaseous and lower jurassic) and divalent iron (over 10 mg/dm3 in the lower jurassic). The values of subsurface temperature in this area at a depth of 1000 m are about 35°C, at a depth of 2000 m the temperature exceeds 50°C. An optimist scenario includes a possibility of future development of touristic attractions in terms of therapeutic resorts in the Warsaw region.

Geotectonic events in the Indochina Peninsula, associatted with the Indosinian orogeny between the Paleozoic and Mesozoic, has created many fold structures and fault areas oin the territory of Laos. Magmatic processes and Earth’s crust deformation enabled arising of rich Cu mineralization. A prospective area for the occurrence of Cu, Ag and Au minerals is the folded region on Muang Xay, northern Laos. The main purpose of geological research of the Muang Xay area was the recognition of chemical and mineralogical composition of rock samples and the evaluation of the area of potential geological resources. During field reconnaissance in 2018, the rock samples were taken from an abandoned mine. It was concluded that primary rocks suffered intense Na-metasomatic processes, preserving primary copper sulphides – bornite, chalcocite and covellite. The content of Cu is up to 49.64% and Ag up to 119.5 ppm. As a result of metasomatism of igneous rocks, diorite or andesite types – albitite was formed. Albitite is composed of medium-grained albite, Mg-chlorite and Cu-carbonates. The prospective research shows that the Muang Xay region has a high potential of metalliferous deposits.

In view of the shrinking reserves of the Bełchatów lignite deposit in the currently exploited Bełchatów and Szczerców fields, the prolongation of the Bełchatów power plant activity, producing about 20% of Polish electricity, requires access to new deposits. The article presents a preliminary analysis of mining opportunities for the Bełchatów – Kamieńsk field deposit, located in close vicinity of the power plant. The assessment of geological parameters of the deposit and the conditions of possible mining exploitation, as well as external (natural and anthropogenic) conditions, is presented. Analyses have shown that despite the favourable quality parameters of coal in the Kamieńsk field, the deposit has no value as a reserve base for the Bełchatów power plant due to its geological conditions and the depth to the deposit. In addition, surface development facilities prevent profitable exploitation of this deposit. In conclusion, it was pointed out that the location of the external dump in the immediate vicinity of the Bełchatów – Kamieńsk field deposit is not the main reason why the profitable exploitation of this deposit is not possible.

Suwałki Anortosite Massif (SAM) occurs in the crystalline basement of NE Poland within 200 km of the magmatic, Mesoproterozoic AMCG (anorthosite–mangerite–charnockite–granite) rock suite terrane called the Mazury Complex. SAM was discovered as a result of the drilling research of the prominent negative magnetic and gravimetric anomalies. There is an extensive negative anomaly of both potential fields related to the anorthosite massif. Gravimetric anomaly is surrounded by the bands of positive anomalies caused by rocks with elevated densities, such as granitoids, monzondiorites and granodiorites. A negative magnetic anomaly is surrounded by the bands of positive anomalies with significant amplitudes, particularly strongly marked from the south, west and north. Positive magnetic anomalies are associated with the presence of rocks with proven strong magnetic susceptibility due to the content of ferrolites (ilmenite-magnetite rocks) with accompanying Fe-Cu-Ni-Co sulphide mineralization. Fe-Ti-(V) ore deposits in the SAM were discovered in the early 1960s, in the region of Krzemianka and Udryn, but also Jeleniewo and Jezioro Okrągłe, under a thick overburden of Phanerozoic sedimentary rocks within small positive magnetic anomalies. These deposits were documented in about 100 deep boreholes to a depth of 2300 m, and the resources in C1 + C2 category were estimated for about 1.5 billion tons of titanium-magnetite ores with vanadium, mainly in the Krzemianka and Udryn ore fields. The model age obtained by the Re-Os NTIMS method for Fe-Ti-V ores and sulphides from the Krzemianka and Jezioro Okrągłe ore deposits was 1559 ±37 Ma with an initial ratio of 187Os/188Os = 1.16 ±0.06. This age was recognized as the age of the entire Suwałki Massif. Despite many years of research, the deep structure and the form of the massif has not been fully recognized. At present, geophysical and geological 3D modelling of borehole data is carried out using the OasisMontaj (Geosoft) software package. The 3D model is generated in the GeoModeller 3D application (Intrepid Geophysics) in order to recognize the geological correctness and interpretation of magnetic-gravity anomalies of the whole massif and its cover.

Based on the discussion on the sources and mechanisms of environmental conflicts (especially those related to mining activities), it was pointed out that the structural model of conflict (the so-called ‘circle of conflict’, introduced by Ch. Moore in 1986) can, and even should be, supplemented with additional, new items. As a result, it forms a spatial solid, i.e. ‘cylinder of conflict’. The authors believe that the addition of supplementary elements will form a solid, with emotions and language codes as the ends, which may be both the cause and the result of the conflict. The authors decided to supplement the ‘circle of conflict’ based on the analysis of the literature and their own experiences. The authors paid attention to the change in the dynamics of the system, in which the remaining causes of the conflict ‘mix’ and collide constantly, overlapping and growing, which may lead to escalation and final disruption of relations between stakeholders. Thus, the discussed model itself takes on an even more dynamic character than the ‘circle of conflict’. According to the authors, it is a good metaphor for the issues discussed, and probably also for any other conflicts.

As part of the research subject of the Polish Geological Survey, funded by NFOŚiGW, a research project was carried out at PGI-NRI in 2015–2018. Its main task was quantitative and qualitative identification of elements accompanying the main ore and associated elements, including critical ones, and mineralogical identification of their main carriers in metallic ore deposits documented after World War II, representing the main metallogenic formations in Poland. The research focused mainly on drill cores from historical survey boreholes, rarely samples from open-pits and deep mines, representing: Mesozoic Zn-Pb ores, Lower Zechstein Cu-Ag ores, Mesoproterozoic Fe-Ti-V ores, Mo-Cu-W porphyry ores, stratiform Sn ores in the Sudetes, Variscan vein and metasomatic Au-As polymetallic ores, and Cenozoic Ni ores. The PIG-PIB Chemical Laboratory performed analytical work (ICP-MS, WD-XRF, GF-ASS), which allowed quantitative identification of approximately 60 chemical elements. In addition, complementary mineralogical and petrographic studies of the trace element carriers were carried out using a polarizing microscope and an electron microprobe (CAMECA SX-100). Before sampling, metal ore-bearing intervals were examined for the content of chemical elements using a portable spectrometer (Olympus XRF Delta). The results indicate the presence of numerous elements in studied deposits, including those currently regarded as critical for the European Union economy. The collected materials allowed both developing detailed geochemical and mineralogical characteristics of ores from individual deposits and identifying critical elements. They show a clear correlation with the main ore metals, and their resources can be a matter of interest in terms of raw materials.

In the hyporheic zone, exchange of surface water and groundwater takes place. During the groundwater drainage and the increase in hydraulic gradient, this zone can be fluidized. The paper presents a mathematical model of hyporheic zone fluidization. It has been obtained from a balance of forces related to the water filtration through the hyporheic zone. The mathematical model makes it possible to predict the occurrence of fluidization depending on the increase in water table position. A series of laboratory tests were carried out, which confirmed the predictions according to the model. The hydrological and hydrogeological influences of hyporheic zone fluidization were also analyzed, namely: the decline of diurnal water level fluctuations in headwaters and the variable rate of decline of water level after rainfall flood.

Due to the planned exploitation of the Gubin lignite deposit by opencast method, a numerical hydrogeological model was built. The main goal of the model was to forecast the development of the cone of depression caused by the future mine dewatering. Due to the location of the mine near the Nysa Łużycka River, a drainage system will be developed. The main task of this system is to eliminate the development of the cone of depression in the upper Quaternary aquifer in Germany, as well as to protect the Natura 2000 areas located in the immediate vicinity of the mine against harmful effects on groundwater-dependent ecosystems. The modelling studies allowed analyzing the efficiency of slurry walls, deep barriers of recharge wells, and shallow soakaway systems for water from the future mine dewatering. It has been shown that in case of dewatering of a multi-layer aquifer complex with many hydraulic contacts, the use of slurry walls may be insufficient to limit the development of the cone of depression. However, the combination of slurry walls with the systems recharging the aquifers enables effective counteracting the negative impact of dewatering on the environment.

The article presents the results of research on the renewal of a hydrogeological system that is characterized by a significant discrepancy of the location of groundwater and surface watersheds. The area of the hydrological and hydrogeological studies is part of the P-IX balance region (Warta River from the Prosna to the Mosiński Canal) located south of the Warta River. The evaluation of groundwater renewability has been made using a hydrological method and mathematical modelling. When using the hydrological method, which is a commonly used control method for water balance calculations, it is assumed that the surface and groundwater watersheds are identical. Comparison of the results of water balance calculations obtained with both methods required the assessment of the compatibility of the groundwater catchment and morphological boundaries. This was done by calculating the difference between the quantities of renewable resources determined by two variants of the hydrological method. In the first (standard) variant, renewable resources were determined based on data from water-gauge and hydrometric profiles closing the catchments of the Warta tributaries draining the analyzed water-management regions. In the second (extended) method, they were determined based on data from water gauges controlling the Warta sub-basin. Enlargement of the balanced unit as far as the boundaries of the Warta basin was consistent with the principle that the reliability of calculations of groundwater resources increases proportionally to the analyzed catchment area and the significance of its drainage zone in the regional groundwater circulation (Toth, 1963). The quantity of renewable resources determined by the standard and extended variants of the hydrological method amounted to 107,100 m3/day and 184,000 m3/day, respectively.

The area of the hydrological and hydrogeological studies is part of the P-IX balance region (Warta River from the Prosna to the Mosiński Canal) located south of the Warta River. The evaluation of groundwater renewability has been made using a hydrological method and mathematical modelling. When using the hydrological method, which is a commonly used control method for water balance calculations, it is assumed that the surface and groundwater watersheds are identical. Comparison of the results of water balance calculations obtained with both methods required the assessment of the compatibility of the groundwater catchment and morphological boundaries. This was done by calculating the difference between the quantities of renewable resources determined by two variants of the hydrological method. In the first (standard) variant, renewable resources were determined based on data from water-gauge and hydrometric profiles closing the catchments of the Warta tributaries draining the analyzed water-management regions. In the second (extended) method, they were determined based on data from water gauges controlling the Warta sub-basin. Enlargement of the balanced unit as far as the boundaries of the Warta basin was consistent with the principle that the reliability of calculations of groundwater resources increases proportionally to the analyzed catchment area and the significance of its drainage zone in the regional groundwater circulation (Toth, 1963). The quantity of renewable resources determined by the standard and extended variants of the hydrological method amounted to 107,100 m3/day and 184,000 m3/day, respectively.

Regional models, covering several thousand km2, are usually implemented to reflect the functioning of hydrogeological systems, whose internal conditions exert an influence over long distances. These include rivers (a model of a catchment), groundwater basins (models covering recharge areas), large intakes and mines (models covering capture zones). Due to the manner of formulating the hydrogeological task and accuracy dictated by the scale, such models are forgotten immediately after verifying, archiving and introducing the results into planning documents and studies. A numerical model with an area of approx. 3 thousand km2 is presented, which is subject to updates and successfully solves subsequent tasks from 2010. It shows how the solutions can be approached on a local scale, on the order of several tens – several hundred metres, using a 400-metre discretization grid. The construction of the regional model requires a high amount of documentation, field and computer work. Therefore, we should aim to use regional models in the long-term, as permanent, with the involvement of people who participated in their creation.
