In a region of two lithologic units: the Augustów Plane sandr and the Suwałki sands and fluvioglacial gravels, 134 measurements of radon concentrations in dwelling houses were performed. An integral method of solid state nuclear trace detectors (SSNTD) was used in the studies. Statistically significant differences in the radon concentrations in both geological units were obtained. The radon concentration arithmetic mean was 197 Bq m-3, geometric mean - 119 Bq m-3, median - 111 Bq m-3, the maximal value being 1225 Bq m-3 in the region of the Suwałki fluvioglacial sands and gravels. The Augustów Plane sandr revealed arithmetic mean of radon concentration equal to 123 Bq m-3, geometric mean – 80 Bq m-3, and median equal to 67 Bq m-3, maximal value 695 Bq m-3. The annual effective dose of the radon obtained by inhabitants of the Augustów Plane sandr is 1.7 mSv and for inhabitants of the Suwałki fluvioglacial sands and gravels it is 2.5 mSv.

The department of a reservoir engineering of "Ukrainian Oil and Gas Institute" is engaged in creation of constant-operating mathematical models of deposits. The mathematical models have been created for productive formations of approximately 20 deposits of Ukraine. Conditionally process of construction of geologic model can be divided into some stages which are connected among themselves: Creation of structural model of a deposit. Structural constructions are understood as structural surfaces of a roof and a base surface of interlayer and seams. Basic data for construction of structural surfaces are results of geophysical investigations of wells. Seldom, at presence, the seismographic observation are used too. Creation of a three-dimensional grid. Modeling is surveyed on a three-dimensional grid which describes internal volume of a deposit. The reservoir is divided into separate hexagon cells. The organization of seams of a grid displays the structural and tectonic effects which are available in a deposit. Modeling of space distribution of collecting properties. The purpose of this stage is getting a representation about space distribution of reservoir characteristics. Space distribution of parameters is carried out similarly to structural constructions. A small well stock often necessitates an alteration of geologic model of deposits and it happens to come back to the beginning of modeling and reconstruct models.

This paper presents the available pieces of evidence on neotectonic structural evolution of the Polish segment of the Outer Carpathians. During the Late Neogene, structural development was largely controlled by normal faulting and block uplift. However, there are also indications of compressional stress setting, at least during the Pliocene and particularly within the medial and eastern parts of the belt. It follows that during Late Neogene times the stress arrangement could have been differentiated depending on time and the position in the belt. In the Quaternary, in turn, structural development has been mainly controlled by compressional stress arrangement, with q, oriented roughly perpendicular to the belt. Furthermore, the vertical differentiation of the S(Hmx) indicates a two-tier arrangement of the stress fied. On the other hand, in intramontane basins and in frontal parts of nappes and larger slices, localised normal faulting took place. Finally, the intensity of tectonic activity within the belt has been changing throughout the Quaternary. It appears, therefore, that the Quaternary stress pattern within the Polish segment of the Outer Carpathians has been differentiated depending on depth, position in the belt and time.

Applying dynamic reservoir characterization techniques requires integrating the geologic framework of the reservoir, the reservoir processes of manipulating the fluids and pressures within the reservoir and the anticipated seismic response observed over time using surface seismic data. It is useful to gain an appreciation of general seismology in order to relate the seismic measurements to the reservoir under study. In the following sections, we present basic seismic theory, the relation to the reservoir through rock physics, and then increase the complexity of seismic theory to approach a realistic view of the reservoir framework and conditions. Being able to predict, or reservoir processes, the elastic seismic response to a given reservoir state allows us to invert an observed seismic response to the actual reservoir conditions. Repeated measurements over time provide the dynamic aspect of reservoir characterization, allowing prediction of future reservoir performance. In "Multicomponent seismology — part I", we introduce elastic wave propagation, relating the stress and strain of a propagating seismic wave, the stiffness tensor, the wave equation and elastic wave modes in isotropic media. Simple half-space models shows changes in P- and S-wave reflectivity due to changing fluid types in porous sandstone. Generally speaking, many reservoir time-lapse seismic signatures associated with compressibility changes in the bulk rock properties can be modeled using basic, isotropic assumptions. Examples include replacing a compressible fluid with an incompressible fluid such as a reservoir producing high GOR oil with strong water drive or water injection support. A second example would be heavy oil production using steam-assisted gravity drainage. In both of these cases, changes in bulk rock compressibility are the dominant variation over time, observable using P-wave time-lapse seismic data.

Geologist, a graduate of the Warsaw University, and in the years 1974-2009 Director of the Museum of the Earth of the Polish Academy of Sciences in Warsaw. He was the author of over 250 works in geology, protection of inanimate nature, history of geology and museology. Well-known for his activity in national and international museological organisations, as well as for his work in the history of science. The Museum of the Earth existing in Warsaw since 1932 is a scientifi c-educational institution of geological and nationwide character. It looks after specialised departments of regional (provincial) museums. In recent years, the Museum specialises mainly in research on ambers and its exhibitions (permanent and temporary) have been organised in many countries. The article presents an outline of academic biography of the Museum’s Director, substantiated with a selection of most important publications. It was stressed that due to certain circumstances he quite early dropped his fi eld studies. At that time he became actively involved in the protection of nature (especially the protection of erratic blocks of Scandinavian origin) and published a book Zabytki skalne in this subject, as well as several brochures. Simultaneously, he dealt with the history of geology, using the archives of the collection of the Museum of the Earth. The article aims at presenting a profi le of the Museum of the Earth: of educationalrescue character vs. scientifi c-educational one. Jakubowski preferred the fi rst model. Especially in his last articles he stressed that mostly natural museums exhibiting authentic objects to the visitors are exponents of an idea of “knowledge authentication”.

Since 50 years copper-silver ores have been extracted from the Lubin-Sieroszowice deposit located on the border between the Lower and Upper Permian sediments. It is a world class stratoidal type deposit. In the whole world the Kupferschiefer unit is recognized as a black, clayey organic-rich shale. The Cu-Ag deposit is a part of the Fore-Sudetic Monocline, and is located on the border of the Lower and Upper Permian strata The monocline includes three rock complexes. The first is the basement, which comprises Proterozoic crystalline rocks and Carboniferous sediments. It is overlain by monoclinally dipping Permian and Triassic sedimentary rocks. In this work, study on ore mineralisation of the red variety of the Kupferschiefer are presented. Oxidation of the Kupferschiefer as an epigenetic phenomena.The oxidized zones reveal low concentrations of simple copper sulphides with the dominating chalcopyrite accompanied by bornite, pyrite, covellite, galena, clausthalite, chalcocite, digenite, spioncopite, geerite, native Au, electrum, tetraauricupride, naumannite, native Pb, Pd-arsenides and minerals of mixed composition: Au-Ag-Pb-Bi-Se-Te, Au-Ag-Pb-Te, Bi-Cu, Bi-Pd and Pd-As-O. Most important are natural alloys of precious metals, Pd-arsenides and oxidized phases (mostly Pd ones), which strongly influence the effectiveness of froth flotation. Precious metals form several parageneses: i - clausthalite - native Pb - electrum - AuPb2, ii - Pt-native Au - native Pd - sobolevskite - native Pb, iii - native Au - haematite - bornite - minerals of covellite-chalcocite group, iiii - electrum - tetraauricupride - chalcocite, iiiii - electrum - Pd-arsenides - tellurides - selenides - BiPd and CuBi natural alloys - Pd-oxides. The red Kupferschiefer variety is distinctly lower in carbonates and resembles rather a marl. Average Fe2O3 content is about 5 times higher than that in the grey Kupferschiefer. The average TOC content in the red Kupferschiefer is about 10 times lower than that in the black Kupferschiefer and about 5 times lower than that in the grey Kupferschiefer. Average Cu content is 1,070 ppm at variability coefficient 81% . The grey Kupferschiefer contains 3 times higher contents of Cu and its variability coefficient is 2 times higher, which points out to quantitative changes during the leaching of copper when secondary oxidation of deposit proceeded. Thus, low Cu and TOC values can be indicative for oxidizing environment and, consequently, can be good exploration guides to zones enriched in precious metals. Average Au content in the red Kupferschiefer is high 15.419 ppm, is much higher than that for the grey Kupferschiefer. Comparison of metal contents in samples from the oxidized zones reveal high variability of Au values in the red, which may change from a few ppm to over 100 ppm. Negative Cu-Au correlation supports the hypothesis on the introduction of gold into the red Kupferschiefer during the leaching of copper. Au horizon is continuous and located close to the bottom contour of Cu deposit. It includes the top part of the sandstone and extends down, even beneath 1 m from the top of the sandstone. The average thickness of the high-Au zones is 0.2 m, and various from 0 up to 1.4 meters. The Au and PGE deposit described in this paper fit well in the world criteria for economic-grade accumulations.

In the paper, results of year-long measurements of radon levels in dwellings on the premises of Silesian Voivodeship are presented. Track etched detectors with polymer CR-39 foils were used in the investigations. As the studied buildings were located in different regions of Silesian Voivodeship, therefore results of measurements were analysed due to possible influence of geological structure or effect of mining operations in places, where given dwellings were situated. Elevated concentrations of radon were measured mostly in dwellings located in areas, where permeable Triassic limestone and dolomite occur, as it has been predicted. On the other hand, the impact of mining activity such as disintegration of rock-body and activation of faults plays an important role, too, because it enables radon migration and its entry into buildings. Beside the analysis of seasonal variations of radon activity concentration, the impact of temperature and pressure on these fluctuations outdoor and indoor buildings has been analysed.

Omówiono budowę geologiczną jednostek reglowych w Tatrach na zachód od Doliny Suchej Wody. Składają się one z dwóch zasadniczych części: regli zachodnich zbudowanych z monoklinalnej kriżniańskiej jednostki Bobrowca i leżących na niej jednostek płaszczowiny choczańskiej oraz regli zakopiańskich zbudowanych z większej ilości drobnych jednostek tektonicznych płaszczowiny kriżniańskiej. Obie te części kontaktują ze sobą wzdłuż strefy nasunięcia regli zachodnich na zakopiańskie. Strefa ta jest jedną z poprzecznych dyslokacji o kierunku SW-NE przecinających jednostki reglowe i nadległy kompleks eoceński.W strefie reglowej Tatr dyslokacje te mają złożoną budowę i najczęściej charakter nasunięć lub uskoków pochylonych ku NW. Tworzą one system imbrykacyjny, interpretowany tu jako kontrakcyjny dupleks. Przesunięcia na poprzecznych uskokach powodują prawoskrętną rotację poszczególnych bloków jednostek reglowych.

The Subtatric zone makes up a longitudinal belt along northern edge of the High Tatra Mts (Fig. 1). It is represented by the Križna nad the Choč nappes of the Inner Carpathians. The western subtatric zone. West of the Kościeliska Valley, the Bobrowiec unit makes up the main subtatric mass (Fig. 2). It consists of monoclinal Triassic, Jurassic and Lower Cretaceous units in the typical Križna nappe development. Its Middle Triassic competent dolostones are split into smaller blocks. Amplitude of fault displacement between these block dimnishes upward. The entire zone is cut by a large Siodło dislocation in its central part. Enrichment in iron and manganese ores (Krajewski & Myszka, 1958), is associated wit the dislocation (Fig. 7). The tectonic sole of the Bobrowiec unit is thrust onto the Hightatric zone along a shear plane (Fig. 6). The Bobrowiec unit is overlain by a higher nappe showing lithostratigraphic characteristics of the Choč nappe (Nemčok et al., 1996). In the western part of the Tatra Mts, it consists of Triassic formations, but in the Kościeliska Valley - of Lower Jurassic ones (Fig. 3). The whole nappe structure had been peneplenised during early Paleogene, being then covered with clastic sediments of Middle Eocene age (Fig. 4). At the Siodło dislocation, and the one that terminates the western Subtaric zone in the east (between the Kościeliska and Mała Łąka Valleys), changes occur in the composition and thickness of the basal Eocene beds (Bac, 1971). The Zakopane Subtatric zone. The Zakopane Subtatric zone makes up a complicated tectonic structure consisting of several nappe units composed of Triassic and Lower Jurassic formations in the Križna nappe development (Fig. 8). The zone consists of two belts of Middle Triassic dolostones with the so-called Czerwona Przełęcz syncline inbetween. The latter is built of Upper Triassic and Lower Jurassic shaly beds. Knowledge of the Subtatric Triassic lithostratigraphy (Kotański, 1963) allowed to state that this part of the Subtatric zone is composed of isoclinal slice elements usually in tectonically normal position (Guzik & Kotański, 1963). Tectonic model of the western Subtatric zone in the Western Tatra Mts. The set of tectonic scales in the Zakopane Subtatric zone makes a form of duplexes in the sense of contraction tectonics (see Boyer & Elliott, 1982; Mitra, 1986). It is proved by isoclinal, normal position of the majority of the scales, with shearing planes cutting horizons of incompetent Lower Triassic and Keuper shales, with passing of overthrust planes into shearing planes. The cross-sections (Fig. 10) are limited to structural elements visible in the field. They show a distinct imbrication of tectonic units in the Zakopane Subtatric zone. One must, however, subtract the effect of postorogenic tectonic processes and, first of all, of a rotational post-nappe tilt of the Tatra massif which caused the nothward dip of the Mesozoic Subtatric sequence that primarily was nearly flat or only slightly tilted toward the south (Bac-Moszaszwili et al., 1982). Within the Zakopane Subtatric zone, the duplexing process had embraced the sequence from the Triassic to the Lower Jurassic. Younger formations are unknown from that zone. Such a process did not take place in the Western Tatra Mts where the Lower Subtatric nappe include sedimentary formations from Middle Triassic through the Lower Cretaceous inclusively. The two above mentioned Subtatric zones namely the Zakopane and the western one, contact with each other in a tectonically complicated area of Upłaz Miętusi. It was argued (Bac, 1971) that there is no superposition of these two zones as supposed earlier by Rabowski (1954) and Kotański (1965). The tectonic structure of Upłaz Miętusi is best explained by an en bloc thrust of the western Subtatric zone onto the Zakopane one (Figs 2-5, 8, 9). The basal Eocene beds also take part in this thrust (Bac-Moszaszwili et al., 1979), and reverse folds so common in the Bobrowiec unit (Bac, 1971; Piotrowski, 1987) are associated with it. Displacement of an upper part of the Bobrowiec unit, recognized in the Chochołowska Valley, also shows a reverse character (Figs 2, 5). Folds in the Zakopane subtatric zone are of similar character (Fig. 11). The Subtatric units of the Zakopane zone are cut in several places by transverse, rather broad dislocations (Figs 8, 9), of fault overthrust character. As follows from studies by Iwanow (1965), and Bac-Moszaszwili & Rudnicki (1979), the above mentioned thrust zones are tilted toward NW, similarly as it is the case with the thrust of the western subtatric zone over the Zakopane one. They separate units differing in structure (Fig. 9) and are accompanied by small retrofolds usually of drag fold type (Fig. 11). The amplitudes of displacements vary in particular units. They are largest in the lowermost Suchy Wierch unit and smallest within the basal Eocene. This suggests a gradual development of this zone that started already during the nappe process, and was subsequently rejuvenated. The development of reverse structures, and transformation of the transverse dislocation zones into flat overthrusts dipping from NW toward SE, may have been caused by the formation of the Parnica Sigmoide at the western termination of the Tatra Mts (Bac-Moszaszwili, 1993) as well as by other tectonic phenomena that took place at the Inner/Outer Carpathian boundary. The last post-Paleogene stage of displacements along the mentioned transverse dislocations, shown in fig. 12, was a clockwise rotation of the Subtatric blocks. This may be one of effects of transpression and block displacements at the Inner/Outer Carpathian boundary. This direction agrees well with results of palaeomagnetic (Grabowski, 1995) and geotectonic studies (Birkenmajer, 1985). The morphological observations done by the authoress (1995) in the Subtatric units led to acceptation of such direction of recent rotation along the north-Tatra lineament.
