The hydrogeological features of the development of the Borok granite quarry, the oldest in Siberia, are considered in the article. It was found that the hydrogeological conditions of the quarry are quite difficult. Two aquifers: alluvial deposits of the Quaternary age and Paleozoic granites were identified according to the geological structure of the quarry, assessing the main hydrogeochemical indicators of the drainage waters of the quarry. The volume of water inflows for the last 70 years has been analyzed. The role of fissure-vein waters of Paleozoic granites, Quaternary aquifer and atmospheric precipitation during the year is substantiated.

Excessive amounts of atmospheric precipitation can cause intense soil erosion, landslides, inundation and floods. Torrential rains have the force to displace and transport soil particles, so the risk of soil erosion becomes real, as many times as atmospheric precipitations have a devastating character. In this context, it is extremely useful to know the particularities of the torrential rains in the current regional climate. At this stage, the Fournier (IF) pluvial aggression index is becoming more and more prevalent. This paper is dedicated to the use of this index with the pluviometric Excess Danger index (IPP) developed at regional level. The results obtained show close concordance between these indices for temporal estimations. Spatial analyzes highlight the role of slopes' orientation in distributing the pluviometric Excess Danger index and slopes' degree of inclination in the case of the Fournier pluvial aggression index. The results obtained are useful in the efficient use of agricultural land and in the elaboration of measures for the improvement of degraded soils.

Solving complex hydrogeological problems often requires a thorough understanding of (hydro-) geological subsurface conditions. This is especially true for sedimentary deposits with complex architecture, where lithology and/or hydraulic properties can significantly vary over short horizontal and vertical distances. At these sites, a traditional, solely sample-based investigation approach is often not applicable due to limited data accuracy, resolution, and efficiency. Instead, an adapted investigation approach is required that combines exploration technologies of different resolution and investigation scales. This paper aims to demonstrate the feasibility of such a multi-scale approach for the characterization of a test site near the city of Löbnitz, Germany, that is comprised of heterogeneous alluvial deposits. Our focus is on site characterization in terms of lithology and hydraulic properties, as well as on the delineation and characterization of an aggradated oxbow as a typical example of a small scale geological structure.

The article presents the concept of petroleum systems modeling in the area with complex fold-thrust belt structure. The aim of the study was to verify the views on the influence of the overtrusting Carpathian orogen on the course of petroleum processes in the basement (Meso-Palaeozoic) formations. The project was implemented in the marginal zone of the Skole Unit (Outer Carpathians) overlapping various structural and tectonic units of the basement. The area of Rzeszów city was selected as it presents adequate complexity of the geological structure to meet assumed methodological objectives of the project and, at the same time, provides relatively vast amount of geological data available which creates a conditions for a comprehensive approach. The study was carried out using the Dynel 2D and PetroMod 2D software. The course of the structural and tectonic evolution of the area was reconstructed in 5 stages, the results of which were subsequently applied in a dynamic modeling of the petroleum systems. The modeling results made it possible to recreate and analyze the course of a complex geological processes, the effects of which are manifested, among others, by the time and amounts of generated hydrocarbons as well as the dynamics of expulsion, migration and accumulation processes. The results show the course of petroleum processes in each stage of the petroleum basin evolution, revealing a special role of thrust tectonic of Outer Carpathians on basement formations. For the adopted assumptions of the structural and tectonic evolution, the generation of hydrocarbons by Lower Palaeozoic source rocks was initiated with the overthrusting of the Carpathians. This increases the chances of their accumulation in reservoir intervals sealed by an overthrusting orogen. This is a positive premise in the context of petroleum exploration in the area.

Abstract Grey Alder (Alnus incana (L.) Moench.) stands are distributed in the Carpathian area on alluvial deposits with sediments of different grain size as galleries along rivers and streams of the sub-montane to the middle montane level. The geological structure (Tertiary sedimentary deposits) in relation to the hydromorphological processes is the base for the structure of the stream valleys, which are in part very deep. Under the special microclimate of these deeper stream stretches with lower temperatures there are favourable conditions for the development of grey alder stands.

Tilt Derivative

<p>Gravity Satellite has been widely used in tectonic studies and regional of geological mapping. The Satellite Gravity data are provided free by Scripps Institution of Oceanography, University of California San Diego. The data are acquired by GEOSAT and ERS-1 satellites with a 1.5 km resolution for one pixel. For a further application, the tilt derivative analytic technique was used in order to enhance linear trends of the geological structure revealed by the Bouguer anomalies. The method is represented by the value of an angle between the total horizontal and vertical derivative from the gravity data. The results show that the tilt derivative calculation has been able to map clearly some geological structures on the north of Sumatra i.e., the Aceh and the Seulimeuem segments, as well as some local faults around them. On the other hand, Banda Aceh as the capital city of Aceh Province and Pidie District is dominated by positive values of the tilt derivative anomalies. The data coincide with geological maps of both areas where they are covered by alluvial deposits. Based on the result, it can be concluded that the tilt derivative method is potentially used for quick interpretation of the satellite gravity data.</p>

Abstract The Miechów Trough and the central part of the Carpathian Foredeep in southern Poland have a highly complex geological structure and numerous fault zones. These features play a significant role in hydrogeological conditions of the area. In this area drinking water, medicinal groundwater or thermal groundwater occur, so recognition of their circulations is basic for reasonable groundwater management. In this note, a hydrogeological conceptual model, created for the purpose of regional scale mathematical modelling, is presented. This conceptual model illustrates the geology of the hydrogeological system modelled, as well as hydrogeological conditions and characteristics of groundwater circulation, as determined by tectonics. Typical of the research area is the wide diversity of geological and hydrogeological conditions. The Busko-Zdrój area, a region with a long history of exploitation of medicinal groundwater, presents the best example.
