	abstract = {Advances in sedimentology and basin analysis provide the foundation for a comprehensive basin-fill model and lithostratigraphic framework of Lake Pannon, Central Europe, highlighting the dynamical changes of the depositional environments. The lake's ca. 8 Myr long evolution began with transgression and deepening, followed by normal regression, forming up to 7 km thick sediment fill. Initial coarse-grained coastal deposits are overlain by offshore to deep-water marls, with varying carbonate- and organic-matter content and include both anoxic laminites and sediment gravity-flow deposits. Later confined and unconfined turbidite systems developed due to interactions between basin-floor relief and shelf-slope progradation. Stacked deltaic cycles followed by clayey alluvial plain deposits with anastomosing and meandering sandy channel fills comprise the upper part of the succession. Repeated aggradational to progradational clinothem architectures, thickness and distribution of muddy to sandy delta lobes on the shelf, and distribution of turbidite lobes in the deep basins reflect lake-level fluctuations. While climate primarily controlled lake level, coastal sedimentation is identified as a new factor driving long-term lake-level rise. Therefore, Lake Pannon's stratigraphy demonstrates that, in contrast to marine systems, in supply-dominated endorheic lakes accommodation space is created by sedimentation.},

Leveraging detailed petrophysical datasets from 128 hydrocarbon exploration wells within the Szolnok Formation in southern Hungary, the developed machine-learning workflow—combining XGBoost regression and spatial residual correction—accurately delineated permeable channel systems suitable for thermal energy injection and extraction. The model achieved robust predictive performance (R2 = 0.92; RMSE = 0.24), and correlation analyses confirmed significant relationships between predicted channels and sand content and shale content. Clearly identified high-permeability channel zones facilitated strategic well placement, significantly reducing the risk of premature thermal breakthrough and enhancing the reliability and efficiency of UTES operations.},

	abstract = {The geological conditions of the Villány Thermal Karst (VTK) area in southwestern Hungary provide an excellent opportunity for hydrogeological research on hypogene cave formation along the boundaries between the unconfined and adjacent confined carbonate regions. The aim of this study was to investigate the hypogene caves of the VTK area from a hydrogeological perspective to identify the effects of waters flowing upward and downward and the related speleothems. Special attention was paid to evaluating the current hydrogeological conditions and their potential for cave formation. Therefore, an in situ experiment was conducted in the largest cave situated at the karst water table. Based on these results, the karst development of the area was reconstructed, integrating the results of the regional groundwater flow system evaluation with the geological evolution history. The results showed that all the caves of the VTK region show the effects of upwelling thermal waters. However, features directly related to the infiltration of precipitation are also abundant. During the in situ experiment, microscale dissolution and significant carbonate precipitation were observed in the cave, primarily near the water table, indicating that active cave formation is not currently occurring. The development of the hypogene caves in the area was initiated by the inversion of the Pannonian Basin, during which compression-driven overpressured fluids could have interacted with the topography-driven flow systems recharged through the exhumed surfaces. However, the topography-driven flow systems have recently overwhelmed the overpressured system, and karst development is now governed by epigene processes.},

	abstract = {S-wave seismic data are unaffected by natural gas trapped in strata, making them a valuable tool to study evaporite facies comparing to P-wave data. S-wave seismic data were utilized to construct an isochronous framework and analyze evaporite facies by seismic sedimentology methods in the Quaternary biogenic gas-bearing Taidong area, Sanhu Depression, Qaidam Basin, NW China, with calibration from wireline logs, geochemical evidences, and modern analogs. Techniques of phase rotation, frequency decomposition, R (Red), G (Green), B (Blue) fusion, and stratal slices were integrated to reconstruct seismic geomorphological features. Linear and sub-circular morphologies, resembling those observed in modern saline pans such as Lake Chad, were identified. Observations from Upper Pleistocene outcrops of anhydrite and halite at Yanshan (east of the Taidong area), along with lithological and paleo-environmental records from boreholes SG-5, SG-1, and SG-1b (northwest of the Taidong area), support the seismic findings. The slices generated from the S-wave seismic data indicate a progressive increase in the occurrence of evaporite features from the K2 standard zone upwards. The vertical occurrence of evaporite facies in the Taidong area increases, which coincides with the contemporary regional and global arid paleo-environmental changes. The interpretation of Quaternary stratal slices reveals a transition from a freshwater lake to brackish, saline, and finally, a dry saline pan, overlaid by silt. This analysis provides valuable insights into locating evaporites as cap rocks for biogenic gas accumulation and also into mining the evaporite mineral resources in shallow layers of the Taidong area.},

	abstract = {Formation of commercial microbial gas accumulations requires specific migration and accumulation conditions which can be effectively provided by groundwater flow systems. Namely, if microbial methane can be gathered and transported in aqueous solution over large lateral distances, great amount of free gas can be exsolved where flows turn upward causing a decrease in solubility. Based on this concept and the flow pattern of regional scale topography-driven groundwater flow systems, the present study built a simplistic 2D model in MS Excel including a methane solubility database with 32000 data. The model can calculate the required flow pathway length to saturate groundwater with methane, the amount of free gas that can be released in a potential accumulation zone, and the necessary time interval for the whole process. Application of the model was demonstrated based on the geological and hydrogeological conditions of a study area in the Central Pannonian Basin (Hungary) focusing on the Hajdúszoboszló gas field. In light of the upscaled results of the 2D model, the known microbial gas accumulations of the study area could be charged according to the model. In addition, parameter sensitivity analysis also provided valuable insights into the complex mechanisms of microbial gas migration.},

	abstract = {Climate change and increasing human impacts are more emphasised in recharge regions, where the main flow direction is downward, resulting in negative water balance. Two wetlands located in the recharge position of regional groundwater flow systems were investigated in the Nyírség region, Hungary, as pilot areas for representing wetlands in similar hydraulic positions. Hydraulic data processes, chemical data evaluations, and numerical simulations revealed that the wetlands are fed via local flow systems, superimposing regional-scale recharge conditions in the area. The wetlands are discharge and flow-through types in connection with local flow systems. Nevertheless, in the case of significant regional water table decline—due to the high vulnerability of recharge areas to climate change—local flows are degraded, so they are not able to sustain the wetlands. To preserve the groundwater-dependent ecosystems in the areas, water retention at the local recharge areas of the wetlands may help in the mitigation of water level decline under present-day conditions. If the regional water table continues to decline, comprehensive water retention solutions are needed in the whole region. The results highlight that understanding the natural wetland–groundwater interactions at different scales is crucial for the preservation of wetlands and for successful water retention planning.},
