Artificial Intelligence (AI) combines Machine Learning (ML) and Large Language Models (LLM) on which ChatBots, e.g. GPT-4, are based. Itis accepted and appreciated in almost all areas, but in education it still raises many controversies and concerns. The sooner we introduce ourselves and students to it, the less we will fear it and the more successful our students will be. We should introduce AI elements into most courses, first of all teaching students to interact with ChatBots. It would also be good to create courses with the basics of Machine Learning. Various examples of the use of AI in education, in particular in the Earth sciences, are presented, drawing also attention to various problems and threats.

Particle size distribution (PSD) and concentration of mineral-suspended sediment released from melting glaciers are important factors affecting the local marine ecosystem, e.g. affecting the light availability in water columns, thus changing underwater light climate for photosynthetic organisms. We examined the characteristics of various samples of natural mineral assemblages suspended in different glacial bays in Hornsund and Kongsfjord at Spitsbergen. The concentrations of the total mass of particles (TSM) in suspended sediment as well as particular organic matter (POM) and particular inorganic matter mass (PIM) together with mineralogical composition and particular size distribution (PSD) were determined. In this study, we investigated the PSD properties and variability in the front of different tidewater glaciers based, laser diffractometer measurements (LISST-100x), and XRD – techniques to obtain the mineralogical composition of the particles. The sampled sites are under the strong influence of freshwater discharge from the glacier. At each station, inorganic particulate matter contributed up to 98% to total suspended matter with the particle concentration of the particle reaches up to 111 mg/l with mean surface PSD slopes ranging from 3.24 to 3.85. The result provides valuable baseline information on the observed range of variability of the size of suspended particles due to glacial runoff and the presence of particles of different mineral origin in the glacial bays.

This paper presents the results of studies on the level of radon concentration in selected residential buildings located in the area of the Rybnik region. A passive measurement method, using alpha particle trace detectors, was applied for measurements carried out in several campaigns between 2005-2010. A total of 122 measurements were carried out in the basements and ground floors of 61 buildings. The exposure time of the detectors ranged from 3 to 6 months. The range of measured radon concentrations was from 10 to 390 Bq/m³ on the ground floors and from 28 to 740 Bq/m³ in the basements. The arithmetic means of the measured values were respectively: 74 Bq/m³ on the ground floors and 128 Bq/m³ in the basements and were higher than the average values calculated for Poland as a whole, as well as for the Upper Silesian Coal Basin (GZW).

Sulpfur has accompanied us since the dawn of time. Wincenty Kadłubek mentions it for the first time, presenting the legend of the destruction of the Wawel Dragon. According to Dr. A. Wójcik, sulphur could have been one of the reasons for moving the capital from Kraków to Warsaw. The exploitation of this mineral lasted about 500 years. During this time, approximately 700,000 tons of sulphur ore were mined in an area of approximately 5 km, drilling approximately 1,000 shafts and leaving 600 heaps. Following J. Esprinohard, Jan Pazdur quotes a message from 1597 that “when the plague prevails in Kraków, which happens often, most of the citizens leave the city and live for some time near the sulphur mine in Swoszowice and no one is affected by the disease at that time”. Sulphur mining is a niche business, currently as much as 99 percent of this raw material is obtained worldwide in large-scale desulfurization processes of gas, oil and exhaust gases. This was not the case before; sulphur mining in Swoszowice was an important branch of the economy of the Kingdom of Poland and the Austro-Hungarian Empire. Sulphur mining in Swoszowice was finally discontinued over 70 years ago, but it is worth knowing the history of mining in this oldest and longest operating mine in Poland.

Emil Lucjan Habdank Dunikowski - a graduate of the Lviv (Lwów), Munich and Vienna Universities, belongs to the circle of the Polish most significant scientists who specialized in Earth sciences and pursued their careers in the Lviv of the Austrian era. Sociable, diligent, and curious about the world, he devoted his time to discovering the mysteries of geology, actively developing Polish research in Galicia. While performing his research-related tasks in various parts of the globe (for example in North Africa, North America, Europe, and Russian Primorsky Krai), he satisfied his passion for travelling, delivering accurately made descriptions of broadly defined nature. In biographical contexts, the Lvovian scientist is seldom mentioned. Despite his undisputable scientific achievements and extensive travel experiences, there has yet to be a comprehensive biographical and bibliographical study dedicated to him. This article outlines his scientific profile and presents some unknown facts from Emil Dunikowski’s private life and career, based on the documents obtained from the State Archives of Lviv Oblast in Lviv (Ukraine).

The Song Hien Rift basin, located in northeast Vietnam, has been identified as an important region for gold deposits, including the Pac Lang deposit. Several methods like petrographic observations, elemental analyses, and geochemical elements and vertical zoning models of primary halo have been used to describe geological characteristic of this deposit. The investigation focused on examining the geological events that occurred both before and after the formation of the ore. The use of ICP-MS analysis and element concentration contrast enabled an effective assessment of the relative degrees of denudation that occurred at the Pac Lang deposit. The findings of this study were consistent with prior research on ore deposit geology, geochemical primary-halo, and examination of geochemical indicator zoning patterns for gold ore bodies. The study's application of singularity analysis for evaluating the degree of denudation provides important geological information that can aid in data interpretation. The results of the study can also have significant reference value in furthering our understanding of the post-ore deformation of deposits and in the investigation of unknown orebodies in northeast Vietnam. There indicate that, the research's findings suggest that the use of singularity analysis to evaluate the degree of denudation is a valuable tool for exploring potential gold deposits and enhancing our knowledge of gold deposit geology in northeast Vietnam. Overall, this study contributes to the existing body of knowledge on gold deposits in the Song Hien Rift basin and can serve as a useful reference for future research in the area.

Geological history of the NW Indian Plate Tethyan passive margin in the Salt Range, Pakistan

The generally east-west trending Salt Range, located in northern Pakistan, is a part of the foreland zone of the Himalayan Fold and Thrust Belt (HFTB). The 5,000–1,000 m thick Precambrian to Pleistocene sedimentary archives of the Salt Range provide an excellent opportunity for the reconstruction of sedimentation style, palaeoclimatic conditions, and tectonic history of the northwestern margin of the Indian Plate. The Precambrian evaporites of the Salt Range Formation are the oldest rocks in the area and represent the westward extension of the Precambrian evaporitic belt that includes the Hormuz Salt Basin (Iran) and Ara Salt (Arabian Plate). A highly weathered igneous body “Khewrite” occurs in the upper part of the formation and can be correlated with the volcanic record during the Ediacaran-Cambrian transition in the Arabian Plate. The clastic-dominated Lower Cambrian succession in the area is directly overlain by the Permian Tobra Formation and with a gentle angular unconformity. The poorly sorted conglomerates of the Tobra Formation indicate deposition during the Permo-Carboniferous glaciation and the irregular distribution of the Tobra and Dandot formations in the area supports their deposition during the syn-rifting phase of the Neo-Tethys opening. The overlying Upper Permian and Mesozoic strata indicate deposition on the northwestern passive margin of the Indian Plate facing the southern margin of the Neo-Tethys. This represents the drift sequence with multiple phases of passive margin rejuvenation during the Mesozoic. The drift sequence is unconformably overlain by the Paleocene Hangu Formation. Karst bauxites mark this contact and hint at exhumation and exposure in the distal part of the underthrusting plate margin. The Hangu Formation grades upward through the Lockhart Limestone into black shales of the Patala Formation supporting deepening and the possible establishment of a trench setting in the area. The presence of thick evaporites of the Bahadar Khel Salt and Jatta Gypsum in the western part of the area (Kohat Plateau) indicates a restricted lagoonal setting during the closure of the Neo-Tethys during the Eocene. The absence of the Oligocene strata hints at the uplift and exhumation of the area during the Himalayan Orogeny. The Neogene strata of the area consist of fluvial-continental detritus and represent molasse sedimentation. Thermal history modelling based on Apatite Fission Tract (AFT) data indicates three major cooling (uplift) episodes separated by two burial phases in the area. The first cooling event (ca. 520 Ma) coincides with the emplacement of the Mansehra Granite just north of the area (ca. 516 Ma) and supports exhumation correlatable with the Pan-African Orogeny. This was followed by the first burial phase (ca. 500–370 Ma) that supports Late Cambrian–Devonian sedimentation in the area. The second cooling event (ca. 300–280 Ma) coincides with the initial rifting and exhumation associated with the Neo-Tethys opening. Therefore, it appears that the Late Cambrian–Devonian strata were deposited in the Salt Range but were subsequently eroded during the exhumation induced by the Neo-Tethys opening during Permo-Carboniferous. This was followed by Neo-Tethyan passive margin deposition throughout the Mesozoic. An additional cooling episode is observable at around ca. 60 Ma and is supported by the presence of karst bauxites at the base of the Hangu Formation. Provenance analysis of the Paleocene strata suggests that detritus for the Hangu Formation was supplied from the south (Indian Plate). The overlying Patala Formation indicates the onset of sediment supply from the north and hence the uplift of the Himalayan Orogen. The overlying Kuldana Formation supports detritus supply only from the north verifying the Neo-Tethys closure by the end of Eocene. Thus the Paleogene strata represent syn-collisional deposition of the Neo-Tethys in the Salt Range. The second burial event (ca. 20–6 Ma) occurred during the Neogene in response to molasse sedimentation in the foreland of the uplifting Himalayan Orogen that was followed by the final cooling and uplift event (ca. 4 Ma) along the Salt Range Thrust. Thus the stratigraphic successions of the Salt Range provide key information regarding the reconstruction of the northwestern Neo-Tethyan margin of the Indian Plate which can help in the understanding of Neo-Tethyan tectonics in regional and global context.

This article presents results for the development of new methods of inserting discontinuity lines into the numerical model of the deposit in CAD systems. The main problem in creating a numerical model of the deposit is usually a very small number, as well as low reliability of the source data. Hence, the authors developed new algorithms for inputting discontinuities, which can be used in particular for conditions when a large number of discontinuities are present. The article offers algorithms for inputting discontinuities into the entire deposit model. The method of transferring faults from the higher seam to subsequent seams and determining the course of the fault in the entire rock mass has been described. The fault can be represented as a spatial mesh of triangles, just like the seam floor. Then the fault can be extended until it intersects with the next seam (with the next triangle mesh) using geostatistical methods. As a result, we determine the exact position of the discontinuity line in the next seam. The paper also presents several algorithms for checking the deposit model made using the methods developed by the authors, including the analysis of outliers (in terms of elevation and inclination), testing the variability of the fault throw, checking the distance between adjacent seams, and verifying the position of the deposit in relation to the existing workings and boreholes. It should be noted that the key issue while building a deposit model is a checking of the model, removal of the assumptions and, obviously, incorrect data in order to obtain the highest possible accuracy.

The largest problem that we encounter when creating a numerical model of a hard coal deposit is to insert discontinuity lines representing faults, seams junction lines, wedging, etc. The faults introduced on the map of the seam are mostly flat polylines, while we do not know the altitude ordinate. In order to determine the spatial position of the faults, authoring methods have been developed and implemented in the Geolisp software and in the CAD system. This article presents the method based on calculating the spatial position of the fault with respect to the existing contours, which arrive at it from both sides, the method based on the assumption that the inclination of the seam in front of and behind the fault is constant, the procedure involving the performing of independent surfaces of the upthrow and downthrow side with extrapolation by the Kriging method, and the procedure requiring the transfer of the fault from the above-lying seam or a Carboniferous roof. The solutions given in the article are successfully used in most mines in Poland. The correct introduction of the fault course is important for the accuracy of forecasting the impact of the mining operations on the rock mass and the surface area.

The article refers to the ongoing discussion around the idea of geological heritage protection. In this context, the genesis, course and results of the activities of the Commission for Nature Conservation of the Polish Geological Institute, operating in 1926–1934, have been recalled. This commission, acting on the initiative of S. Małkowski, contributed to the recognition, implementation and dissemination of the idea of protection of geological features. It also made a significant contribution to the theoretical and practical achievements in this area. Due to many publications, the results of commission's activity were disseminated in the country and abroad. In 1928, the “Zabytki Przyrody Nieożywionej Rzeczpospolitej Polskiej” (Eng. “Monuments of Geological Features of the Republic of Poland”, Fr. “Monuments de la Nature Inanimée de la République Polonaise”) was the only journal in the world that specialized exclusively on the geological features.

Młodsze holoceńskie osady datowano z wykorzystaniem optycznie stymulowanej luminescencji (OSL). Na przykładzie osadów mineralnych zawierających kwarc wyjaśniono podstawy obu technik datowania. Często są one stosowane naprzemiennie, w zależności od materiału i jego szacowanego wieku. Metoda OSL rekomendowana jest do badania próbek na stanowiskach archeologicznych. W obu technikach analitycznych mierzy się wielkości dawek pochłoniętych naturalnego promieniowania jonizującego. Zwrócono uwagę na znaczenie laboratoryjnych źródeł promieniowania gamma w wyznaczaniu krzywych kalibracji.

The article discusses the results of several interdisciplinary studies on the dating of geological sediments with optical methods. The age of older sediments, mainly Pleistocene ones, was determined by thermoluminescence (TL). Younger Holocene sediments were dated using optically stimulated luminescence (OSL). The basics of both methods of dating sediments containing quartz are explained. The OSL method is successfully used to determine the age of mineral sediment in archaeological sites. The basis of both analytical techniques is the measurement of the amount of absorbed doses of natural ionizing radiation. Also the importance of laboratory gamma radiation sources used for the determination of calibration curves has been emphasized.

We provide an update of engineering geological and geotechnical conditions at Gediminas Hill in Vilnius (Lithuania) from 1955 till 2020, which allows evaluation of the stability of its slopes. Active geological processes are still observed on Gediminas Hill. The latest landslides appeared on March 22, 2004 and on March 8, 2008 on the eastern slope above the hiking trail, as well on February 11, 2016 and February 13, 2016 on the northern part of the slope. The latest landslide (involving ~40 m3 of soil) took place on March 7, 2017 between the eastern and southern slopes. Eight hydrogeological units were distinguished in 2017. During 2019-2020 many engineering geological and geotechnical investigations have allowed determination of the possibilities and methods of slope stabilization.

The primary objective of the case study is to improve monitoring, controlling, planning and managing the extraction processes in surface lignite mining. Under the North Bohemian Lignite Basin (also Most Basin) conditions and the Sokolov Basin, wheeled excavators are deployed as the main technology for extracting coal and overlying rock. Their real-time spatial position can be tracked based on data from GNSS technology, inclinometers, and incremental rotary encoders. The measured data is sent to a remote server and stored in the database. It also serves to calculate volumes of extracted masses. Volume calculation, space position visualisation, and wheel boom movements are performed in KVASoftware. It is a program designed for modelling and designing quarries. Knowing the position of the wheel against the digital terrain (quarry), the model is essential for the implementation of many risk-elimination applications, namely with respect to the geological conditions, occupational safety, observance of the profile grade line, the area of extraction, qualitative parameters of the raw material, etc. The mathematical model of backfilling extracted materials is also an integral part of the above-mentioned system.

Traditional methods of mineral exploration are mainly based on very expensive drilling and seismic methods. The proposed approach assumes the preliminary recognition of prospecting areas using satellite remote sensing methods. Maps of mineral groups created using Landsat 8 images can narrow the search area, thereby reducing the costs of geological exploration during mineral prospecting. This study focuses on the identification of mineralized zones located in the southeastern part of Europe (Kosovo, area of Selac) where hydrothermal mineralization and alterations can be found. The article describes all the stages of research, from collecting in-situ rock samples, obtaining spectral characteristics with laboratory measurements, preprocessing and analysis of satellite images, to the validation of results through field reconnaissance in detail. The authors introduce a curve-index fitting technique to determine the degree of similarity of a rock sample to a given pixel of satellite imagery. A comparison of the reflectance of rock samples against surface reflectance obtained from satellite images allows the places where the related type of rock can be found to be determined. Finally, the results were compared with geological and mineral maps to confirm the effectiveness of the method. It was shown that the free multispectral data obtained by the Landsat 8 satellite, even with a resolution of 30 meters, can be considered as a valuable source of information that helps narrow down the exploration areas.

Tradycyjne metody poszukiwania surowców mineralnych opierają się głównie na bardzo kosztownych metodach, takich jak wiercenia oraz metody sejsmiczne. Proponowane przez autorów podejście zakłada wstępne rozpoznanie obszarów perspektywicznych z wykorzystaniem metod teledetekcji satelitarnej. Mapy grup minerałów stworzone przy użyciu zobrazowań dostarczonych przez satelitę Landsat 8 mogą zawęzić obszar poszukiwań, a przez to doprowadzić do redukcji kosztów rozpoznania geologicznego podczas poszukiwania surowców mineralnych. Niniejsze badanie skupia się na identyfikacji stref zmineralizowanych znajdujących się w południowo-wschodniej Europie (Kosowo, rejon Selac) gdzie znajdują się mineralizacje hydrotermalne oraz strefy alteracji. Artykuł opisuje szczegółowo wszystkie etapy badań, od pozyskania próbek terenowych, badań laboratoryjnych mających na celu pozyskanie charakterystyk spektralnych, przez wstępne przetwarzanie oraz analizę zobrazowań satelitarnych do walidacji wyników poprzez rozpoznanie terenowe. Autorzy przedstawili technikę wykorzystującą wskaźnik dopasowania krzywej pozwalający na określenie stopnia podobieństwa próbki do piksela zobrazowania satelitarnego. Porównanie współczynnika odbicia dla próbek względem współczynnika odbicia zarejestrowanego przez satelitę pozwala na określenie miejsc, gdzie mogą występować określone typy skał. W celu określenia skuteczności metody wyniki zostały porównane z mapami geologicznymi. Wykazano, że darmowe dane multispektralne dostarczone przez satelitę Landsat 8, nawet z rozdzielczością 30 m, mogą stanowić cenne źródło informacji, które pozwala na zawężenie obszaru poszukiwań.
